Installed a set of Timbren on our '01 F250 7.3 back in 2008. We just sold the truck two days ago (July of 2021) and they are still on there. Worked from day one with zero maintenance. We towed bumper pull campers, 5th wheel RVs, and my wife's heavy 3-horse trailer with LQ for years with them. Very happy with the Timbren product.

I installed timbren on my 2002 Silverado and sumo springs on my 2002 Tahoe. Theres alot of bounce in the timbren. The sumo springs are alot smoother.

[@Granturry98]

I have a 2003 Tahoe. It sags considerably when we hook the boat up to it. My Tahoe is leveled in the front and on 33's, which makes the rear sag appear even worse. With the sumo springs on your Tahoe, how much sag does it allow, before making contact with the axle?

[@richarde1355]

When you say 'smooth', do you mean the Sumo Springs dampen/recover more quickly than the Timbren? Which model Timbren and which model Sumo did you install? Thanks!

[@RMRMatt09]

How does it rife when not towing and under a normal load?

[@mlaugh3]

@@RMRMatt09 It rides just like stock suspension because the Timbren has not been contacted yet. Once the Timbren reaches a certain load then it will start is job supporting the load. The video explains it pretty good.

[@e.a.r.9155]

Used Timbrens on my RAM1500 towing my 28' trailer from Inland area over Mountains down into Desert n back (San Diego County). They work excellent under lots of weight (even w/ weight distribution bars on trailer would still sink my 1500) and now in Oregon hauling 1ton pallets of wood Pellets home.. Would be impossible for light duty truck without Tembrens. *BUT.. under No Load they are like Concrete bump stops over every speed bump (hurts my kids' rears even in back seat..!) every pot hole, bump, etc. AND makes my truck skip to the side sometimes with such stiff suspension.. (because they only work as suspension under extreme weight, Otherwise THEY DO NOT GIVE..!) So I switch between stock bumps back n forth when hauling or not. Stock bumps pop off, Timbrens will snap in (no bolt) but usually you have to jack up the axle to get them to pop in, I tried a crowbar, couldn't do it..!

Very informative video. I recently installed the black solo Sumo Springs on my 2018 ZR2 because with my camper shell, BedSlide and a full load of camping equipment including water I was near GVRW. At the same time I put on 1” leveling kit in front and upgraded to LT tires with E load rating. Overall the truck still drives very well and I don’t see much difference from stock. The Sumo Springs definitely help with rear sag particularly when carrying a full load.

[@dmmak2678]

Thanks for the great video. Nice job. I have a 1991 F-250 4x4 extended cab, with helper springs installed in the rear only. The truck is used to plow snow and haul water. Winter temperatures can get down to -50F. The truck sags in front (when the 850 lb snowplow is mounted), and sags in the rear (when hauling 2,800 lbs water), even with the helper springs in the rear. I don't want to lose the nice, soft ride that this truck currently has, but I would like to get rid of the front and rear sag, when under load. I would like a system that is reliable and not that difficult to install. It would be nice if it were just a bolt-in application, with no modifications needed. What would you recommend? Thanks.

[@vernlochtefeld1626]

To the point informative & accurate video 👍. I have a small transport business taking travel trailers & boats from Mfgs to dealerships. 5 to 9k often around 6,500 pounds dry. Tongue weights 500 to 1,150 pounds plus sometimes a motorcycle or snowmobile in the bed. Truck is 14 Ram 1500 Ecodiesel so soft coil suspension in the rear. (but great mileage). Anyway to compliment a WDH, plus provide suspension dampening control & support is quality axle to frame air bags. Fixing sag if not using a WDH is actually a side benefit though many newbs buy them for that purpose. Since summer of 14 & 765,000 on the truck only had trouble with air leaks requiring line replacement once but I don’t live in a cold climate here in mid Ohio. Anyway I have a friend & fellow transporter and a son in law both with the same truck. The Sumos in one & Timbrens in the other. Have spent seat time towing with both. I have towed son in laws 8k travel trailer with my truck as well as his same except I have axle to frame air bags sumos on his. Mine rides smoother with better suspension control on rough pavement but otherwise is the same. The black Sumos still much better than friends Timbrens IE not not harsh or jumpy with the wrong load over wash board, expansion joints, or speed bumps like with the Timbrens. No sway with either truck. In short if you don’t want air the Sumos are much better than Timbrens for certain loads and the same ish with other loads.

Thank you for this informative video! I own a Class B Mercedes Sprinter RV (2016 chassis / 3500 Model) dually. With the SumoSprings set up to decrease body sway over bumps and higher winds while driving, would the "black" colored choice be used for both front and rear axles as the ultimate set up? ...or I wasn't sure if one would use the blue in the front and the black in the rear. Thank you kindly for your advice and expertise!!

[@Truckspring]

On the Sprinter model motor-homes the most benefit for sway resistance will be gained with a higher capacity kit, but depending on the load for that axle you are free to use different density kits. On the front the SSF-106-47 is the more popular option and the highest capacity for the 2wd models. On the rear, a Maxim style kit that is attached on both the top and the bottom will help the most with sway issues. The heavier capacity will give the most benefit. The SSR-336-54-1 is yellow in color and it is the heaviest for the 2wd. On Sprinter vans you must check for a rear axle spacer under the factory bump stop. If your motor-home is equipped with the axle block you will not be able to use the Maxim rear kit. Instead, a solo type kit will need to be used.

[@Truckspring]

Typically, The SumoSprings are the more popular option on motorhomes as ride quality is the priority. If very heavy loads or a trailer is to be used the Timbrens may be a better option for the rear. Please feel free to give us a call and we can go over options with you.

[@guygravel4804]

Great video, my question..

[@Truckspring]

On some applications SuperSprings produces SumoSpring kits for specific GVWR and GAWR. This may be based on the weight that the vehicle is designed to carry or is may be based on differences in the chassis or suspension between the different weight ratings. If there is a specific kit for your F53 based on the GVWR you should always stick to that kit to ensure proper fitment.

[@Will-bp2yc]

I tow a 15,000 lb. Fifth wheel (aprrox. 3-4K tongue weight) The ride and handling is great! Timbren's 's are great but, when empty with around 500lb. in your truck the Timbrens come into contact with the frame. (This will give you a hard ride) . Having previously owned air bags, ( can be adjusted for weight) also a great ride loaded. The problem with air bags is even when you aired down to 5lbs. they still ride horrible empty. (its because both ends are attached to frame and axle). The answer to Timbrens empty ride problem: Re arc leaf spring or go with Roadmaster Active Suspension. I chose the latter.

[@Truckspring]

SumoSprings tend to give the best results on motorhome applications. Since you will be carrying extra weight in the back a heavier set of SumoSprings will benefit you more since they will be able to assist with supporting the extra weight and helping with sway.

[@Truckspring]

Unfortunately, the options are limited on the Expedition due to their suspension design. The only helper option that we offer is a Coil SumoSpring and the rear coils will need to be measured for fitment. With the vehicle sitting on the ground we would need to know the gap between two twists at the center of the coil. Coil SumoSprings will provide a 30% boost in coil by resisting compression.

[@jaymackay4303]

I have a specific SumoSprings question: On an F-150 4x4 single cab SWB with a 2" front level on Snow Plow/medium duty front suspension, which color/weight would you use for a 1300 lb camper that transfers a little weight forward and being used off road?

[@Truckspring]

With a front leveling kit you may not see any benefit from a front fixed load support kit. A fixed load support kit like the SumoSprings may not even contact until sag has already occurred past the 2" leveling kit and by then the benefits may not be noticeable.

[@Mr_brut3]

Great video .. I have a 2008 Toyota Sequoia springs are sagging should I replace the springs then add some sumo ?? Or add helper bags ?? I tow a travel trailer when we go camping .. what should I do

[@Truckspring]

If the stock springs are sagging it is always best to address issues with the base suspension system before adding additional load support kits, the truck and the kit will work better if everything is healthy. For a truck that hauls infrequently I would recommend using a fixed load support like the SumoSprings so they will always be ready when you need them. An air spring kit works great for trucks that haul often but it is easy to forget to check pressure when you only use it a few times a year.

[@Mr_brut3]

Michigan Truck Spring thanks I will do that

[@jimmiller4608]

I have a half ton truck and pull travel trailer. Which application would you recommend?

[@Truckspring]

The best kit will depend on the weights that are being carried by the truck. What is the weight of the trailer when it is being towed or the hitch weight?

[@franki5506]

I have an 08 Tundra TRD. I use it as a work tuck and occasionally carry heavy loads. Would either option help with sag and protect my truck from damage?

[@Truckspring]

Both a Timbren or a SumpSpring could be used to help minimize sag when your truck is loaded. The kit that you use should be based on the weight that you carry and keep in mind that the kits will need to allow a set amount of sag before they begin to carry weight so there will always be a bit of sag when loaded.

[@lj5245]

YES I WOULD GO WITH THE SUMO FOR A BETTER RIDE THE TIMBRENS ARE GOOD BUT THEY WILL JAR YOUR TEETH LOOSE.

[@JL-qf3hq]

Do these products shift the load onto the Timbrens/sumo springs instead of the leaf springs, essentially doing the work of the original suspension system? Seems like Timbrens don’t compress enough to activate leaf springs or am I missing something?

[@TheNetcase]

Your springs will sag first then the Timbrens take over. Timbrens are suspension enhancements not a suspension replacement.

[@mondoalvarez2486]

Should I change my shocks before installing any application?

[@Truckspring]

Replacing shocks is not required but if you are upgrading a truck that has seen some miles, replacing the shocks while adding a load support option can improve the stability of the truck when hauling. We recommend considering Bilstein shocks.

[@swervinsearles2315]

Would sumo be better suited for an 18 f150 that occasionally hauls a 6000lb camper (ball hitch) and sometimes has dirt bikes in the back? I’d prefer a smoother ride when unloaded.

[@Truckspring]

Both the Timbren and Sumo offer a smooth unloaded ride as they do not contact the axle when unloaded. If you want to avoid the possibility of a harsh contact on big bumps the Sumo is preferable as the softer material is not as jarring on sudden axle contact.

[@Truckspring]

SumoSprings are recommended on most motorhome applications due to their more forgiving ride quality. The Sumos will offer some extra load support without being too stiff. The SSR-181-54-1 SumoSprings Maxim will fit the rear of a 2002 F53 with a 22,000 GVWR and the SSF-172-40-2 will fit the front.

Do both of these add to towing capabilities vs getting a bigger truck ?

[@Truckspring]

Both Timbren and SumoSprings will help you support more weight and prevent the rear of your truck from sagging when under a heavy load. No load assist, helper spring type product will increase your towing capabilities. There are many factors such as braking, transmission, tires, etc that are used when determining towing capacity.

[@jacaughron55]

[@Truckspring]

Currently, SuperSprings does not produce a SumoSpring product for your truck. Timbren would be the way to go for your application but we will need to know if it is a 2WD or 4X4 and how heavy the travel trailer is to make an exact kit recommendation.

[@richardmartin4608]

Thanks for the insight. Just for confirmation, you recommend the small Timbrens for a plow. I am putting a Western Unimount onto a 2005 Explorer and the smaller Timbrens would be the correct installation. Is this correct. Thanks.

[@Truckspring]

Depending on the front suspension there may not be a Timbren kit available. For the 2005 Explorer the only Timbren kit that is available will only work if it is equipped with the Twin I beam style front suspension. If your Explorer has a strut type suspension there is no Timbren kit available but there are coil sumo kits available for the strut style suspension that will help with the load carrying ability of the coils.

[@DonaldTrumpIceCream]

I have a regular cab 2017 Silverado with 2 inch blocks in the rear for a lift. My reason to getting summosprings is only to soften the ride quality, not for towing. Is this a good idea? And is there a way to have the springs constantly touching the frame even with the lift? Thanks in advance

[@Truckspring]

Both the SumoSprings and Timbrens are meant primarily for load support and the Sumosprings may not provide the ride smoothing you are looking for in this situation. The brackets that are included will not support the extra space left by the lift and you may have to fabricate taller brackets to get the spacing that you want. In this situation I would not recommend one of the fixed load support options. It may be better to look into upgraded shocks depending on what is causing the rough ride.

[@HILDEBRANDimage]

I have a 2017 F150 4x4 and haul a pull behind RV trailer, which when attached does sag a bit. Which brand would you recommend to eliminate the sag. Thanks.

[@Truckspring]

Both the Timbren and the Sumo Spring will help limit sag but they do need the suspension to compress some before they make contact and begin to carry the weight. On a full size pickup I would recommend use of the Timbrens for the rear when pulling an RV camper. If you want the truck to sit at a stock height with the the camper loaded you will need an air spring kit to actually raise the truck back to stock height with a load.

[@Truckspring]

A Timbren it may be the better option when towing your travel trailer. The Timbren kit GMRCK15S will add support and prevent sag and when the truck is unloaded the Timbren Aeons will not touch the axle so the ride quality will remain the same. The SumoSprings may be a little on the light side as far as load support is concerned so they may not completely eliminate sag.

They are designed to improve the ride when loaded and not impact the ride with no load. If you suspension is in good condition they will not improve the ride with no load. We recommend Bilstein shocks to improve the ride when not loaded.

Just bought a set for my ram 1500 installed in five minutes easy set up. Quick question they look like the will hit the beam before the go flat on the load support is this a normal ? Thank you any help or thoughts

[@josepires4345]

That’s great!…you had what installed?

[@infomillcroftlawncareco.lt1739]

Timbers on my 1500 works great should be mandatory for all trucks

[@timalfrey1874]

You make these for orvs Ranger1000xp?

[@Truckspring]

They currently do not make anything for ORV's.

[@marioalvarezvilla2464]

Timbren is rated for 5k+lbs since its hallow, sumo is rated from 900 to 1500 lbs since it has air but its more Cushion

[@wotysgtb4348]

Exactly. The people that have a harsh ride with the Timbren's have them too close to the axle. 1 3/4 to 2" gap is perfect. great ride but has the firmness when needed to tow heavy tongue weighted trailers.

I have a 2017 Ram 2500 (off road pkge) that is used 20-25% of the time to haul a 5th wheel . I get a little sag, what do you recommend?

[@Truckspring]

For your application and usage I would recommend a Timbren kit. You are towing frequently and the 5th wheel is squatting your Ram 2500 so a kit with higher capacity like the Timbrens will give you more benefit. For a 2017 Ram 2500 the recommended kit is a DR2500D. Both will work for your application, but the Timbren kit will give you some extra support.

I have a 1993 D250 Dodge which I tow my 12,000 pound fifth wheel with..weighed at scale the rear end carries 6000 pounds with extra 50 gallon fuel tank etc, the axle is rated for 7500 and the 2 tires are rated for 7000 pounds but the thing sags and wondering WHICH system would give me a better option, interested in the 5000 pound Timbren but it seems they only make the 3000..the bracket seems to be the only difference as far as dimensions of the actual rubber damper...which would you recommend for my application?

[@Truckspring]

For your application Timbren only shows the 3000 LB kit and for the weight you are carrying you may benefit from something with a higher capacity. In this case you may want to look into 5000 LB air spring helper kits to better handle the weight. The 3000 LB Timbren kit may be a benefit but if the axle is carrying 6000 LBS it may still allow too much sag when fully loaded.

[@MrFrodo1111]

@@Truckspring yea..in looking at it further the part that bolts to the truck itself is the same for the D250 or the D350..the only difference is the actual rubber thing..1/2 inch taller but carries 6000 for $100 dolars more or the F2 50 setup with the exact same rubber piece for $214 rather then the $314 for the D350...it seems Timbren has all the parts but does not list for the D250 even though it would fit just fine but it is more ...NOW IF we could buy the metal attachment separate then we can make it work just fine

[@Truckspring]

@@MrFrodo1111 We do not typically recommend using a kit that is not assigned to your vehicle application. It may be best to speak with Timbren directly if you would like a stronger kit for your application. Timbren is open to customizing kits to suit customer's requirements and having them verify fitment will ensure the kit will work as designed.

How does each type hold up in -30°C

[@grantandjanice]

I have blue Sumosprings on my Nissan Frontier (Alberta, Canada) and have used from -35C to +30C I love them. I was so tired of just a few sandbags in the bed slamming the factory bumpstops. Just a tiny bit on the stiff side with an empty bed, but with any load they are perfect.

[@xSILENTNEMESISx]

So im lifting my truck 3 in.. chevy tahoe 02..which is the rec??

[@Truckspring]

A Timbren kit is the recommended option with a lift. They are able to modify kits with spacers or taller aeons to accommodate the extra space created by the lift.

[@Icutmetal]

I just purchased a 2018 GMC 2500HD 4x4 CCSB; I won’t be loading it heavy 75% of the time, but would like to be able to utilize a snowmobile sled deck without any excess sag or sway, which I’d estimate to weigh about 1,500lb. Would you suggest a Timbren/Sumospring over an airbag kit for my application?

[@Truckspring]

If you are only loading periodically I would recommend the Timbren or Sumospring over an air bag system. If an airbag system is not used regularly it is easier to forget to check and maintain the minimum pressures and if the kit becomes damaged due to running on no pressure it will not be ready when you need it. With a Timbren or SumoSpring if you only use it a few times a year or only during one part of the year they will always be ready.

[@stirv6462]

With that light of a load on a 3/4 ton its just getting to the point where it starts to drive the way it should. They're meant to be used the way they are, they ride rougher than crap when empty and only get better when you get some weight on them. 1500 lbs is nothing, it won't even sag enough to touch the timbren thing.

[@Icutmetal]

Stirv I appreciate your feedback. My last truck was a super clean 1997 F350 standard cab; this new 2500HD rides like a couch in a Cadillac in comparison.

[@Icutmetal]

Michigan Truck Spring Thanks for your reply. I like how the SumoSpring “Solo” mounts the same way as the Timbren; they are rated differently, but for less capacity in any case. I’m most concerned with maintaining stability with the weigh up off the bed fairly high, more so than the amount of weight itself. I’m thinking the SumoSpring option will probably be the better option for my needs since I imagine it will also ride a little softer once engaged. Your thoughts?

[@Icutmetal]

I ended up purchasing the SumoSpring Solo SSR-207-47; they sit off my rear axle about 1” or so when unloaded, and maybe a little less than 3/4” with 600lb of snowmobile & cargo in the bed. I don’t think I have noticed them all since installation, and have not loaded the truck any heavier yet. They were extremely simple to install. Wondering what I’ll end up doing if I go with 1.5” blocks in the rear; I know Timbren offers added spacers.

[@qouavang3646]

Damn... Im so stuck.. I do as much offroading as i do hauling... I have a 2015 tundra trd pro... Which should i get..HELP

[@Truckspring]

A SumoSpring kit may be the best option in your case depending on how much weight you are hauling. The Sumos will be much more forgiving when bottoming out off road and they will still support a respectable amount of weight. The SumoSpring SSR-610-54 kit will support 2800 LBS at 50% compression if that much is needed. There are also 1000 lbs and 1500 lbs kits for the rear if you do not need as much extra support.

[@ferasal-khayyat3688]

Which one do you recommend installing for a 2010 Nissan Xterra?

[@davekozbial]

I installed the blue light-duty SumoSprings in my 2014 XTerra. HUGE improvement towing my 1800 lb tent trailer. However, unloaded, there is very little free space, which means the leaf springs don't get to flex much before the SumoSprings start to engage. This makes the empty ride a bit stiff and bouncy, which I hope will improve after I install new shocks.

[@BrockOhhhh]

Considering that sumos aren't available for my truck, I guess I'll go with timbrens.

[@KG7BYT]

Do you grease the 2 piece sumo where they contact?
