RAS active Suspension Install & Review! Tow With Confidence

[@larsstrong3426]

Although the RAS raised the unloaded height and the loaded height the drop was exactly the same, 2-1/8" I expected an increased spring rate and less drop after installation.

[@40delux]

Observed the same thing. I don't see the benefit over bags other than price.

[@larsstrong3426]

The benefit I see over bags is unrestricted travel. Huge benefit. @@40delux

For this load that would be correct, we set it on the lighter setting because Austin does not tow very heavy with this truck. He did report that the real world when towing an 18ft car trailer it did help out but we are also not here to sell you anything, we want these tests to be transparent and that is why we published these results. The sag could have been improved if we went up to the black spacer, we are working on doing a follow-up video on that.

[@pat14lang]

I’d like to see how this helps with pulling a 36’ 9500lb bumper pull camper

[@elcucuygarage]

Same here.

[@stopbeingstagnant]

So moral of the story... spend 500+ and it still sags lol. 🤷‍♂️

[@damiengarrett6545]

Yeah I’d like to see what the max 40% looks like, I’m on the edge on buying this but this video did not give me confidence

[@666joe13]

@@damiengarrett6545 have bags on my ‘16 1500. Bought an ‘03 2500 HD with 3500 leaf springs. I have a trailer that has a significant amount of tongue weight. The RAS + 3500 leaf+ heavy trailer was almost the same as no RAS. About 3+ inches of squat. 1500 with bags. Same trailer. I can get it to level out no problem. I’d say RAS is probably only good for people occasionally hauling about 1k lbs of payload or tongue weight. Anything more, bag it. (Buy a train horn tooooo)

[@piesareround]

Same when i spent $10k on my girls 🍈🍈

[@irvinsalazar4477]

I think the second time you loaded the truck the load wasnt as far inside the bed as the first time, im pretty sure that could mess up the readings somehow

[@jerryberkel8421]

What model is it?

[@juanpabloruizgonzalez4857]

Does it helps with the unload ride?

[@Dmaxstore]

Yes it does!

[@GrantFawson]

Would these plus Timbren SES bump stops be cancelling each other out or would they pair well together?

[@Dmaxstore]

They both accomplish the same task, we have seen the Timbrens cause harshness in ride quality, unlike the RAS. They can be used together as they work in different areas, RAS on top of the leaf spring and Timbren in place of the bump stops. If you need that much load support, I would highly recommend airbags, they will be adjustable and allow you to compensate for whatever trailer you have in tow. The ReadyAir airbag kits are the top of the line if you have a newer truck, otherwise pacbrake offers some really good kits.

[@jacobdaniels6182]

Another thing to note on these they sell a Light Duty and a Heavy Duty version. Wondering what ones we saw in the video.

[@shawndale1552]

The light duty one's. The heavy duty one's will raise the back a inch and half. So you'll have to get the adjustable 6112 bilstein coilovers for the front to level it out.

[@capnmorgandarts]

I'm curious as to how the rear hook stays tight to the rear eye when the leaf spring compresses... it just seems like the hook would loosen from the tension on the coil spring

[@Dmaxstore]

You set it to be very tight when the spring has no load and when the spring compresses it makes the RAS tighter and the leaf spring flattens out as it compresses which means the RAS will only get tighter as it is set to be tight at the smallest point of compression.

[@NSWvet83]

The point of this wasn't to avoid sag. It was for the stability, bounce/rebound.

[@goat165]

They don’t make a model for the Ford expedition. Would the Ford F150 fit on the expedition?

[@ronmason8490]

Why did you leave the forklift once ras was installed, looks a little fishy that way

[@tonytaylor1277]

If camera angle to truck was exactly the same, it appears the load was about 3-4 inches further out of the truck. That would increase leverage, thus skewing results.

[@jerryberkel8421]

I bought a truck that only has 1 side installed. Should I buy another for the other side or is it ok to only have 1?

[@Dmaxstore]

That is definitely not okay to just run one side as the spring rate will be different from one side to another. I would recommend contacting RAS directly to see if they can get you one for the other side.

[@jasondmers6791]

0r take that one off

[@PatrickBaptist]

I'd just take it off and take it to a local scrap yard, that looks like a mistake. All I can think of is it putting extra stress on shackles in a way they were not designed for, I'd rather have none on stock than truck this thing, specially not on one side. The other side prob fell out when the other owner was driving.

[@Merica7617]

Need to put some traction bars on that rear axle help out the driveline and differential.

[@Dmaxstore]

This actually helps reduce axle wrap

[@peters.3375]

Helped with my ride and payload on my Tacoma when it had stock shocks. The only problem is when I upgraded to 2 inch diameter shocks, which is the norm for people to do when replacing Tacomas shocks, it would rub against the shock so I was unable to use my RAS anymore. So anyone with a Tacoma beware. P.S. they would also hit the frame when you bottom out so you would need taller bump stops as well.

[@SM0R3S]

3:40 you make it sound like this increase your ability to carry more weight. This is a dangerous lie. The RAS helps stiffen the leaf spring when carrying a load OR towing to lessen the squat and propoising when you go over bumps and humps.

[@Axeltiguere1976]

Yes, from what I’ve been informed it does not increase payload. It does help to tow it better 👍🏽👍🏽

[@MyCarsandProjects]

The problem with this system is the cost, nearly $600 and it appears to do nothing more than what my heavy duty shock (with helper springs integrated) does for my truck and they were a fraction of the cost. Now, it's possible I'm missing something, but the rate of change seemed very similar before and after the install. I mean whether stock or with the RAS helpers, the sag was still 3/8" either way. Maybe they help ride comfort a lot.

[@DretheDriver]

Difference is you can combine these with the helper shock and yellow sumosprings and watch it ride like magic. 1 twig breaks a bundle wont

[@Justin-il8ij]

​@DretheDriver, at that point, why not purchase airbags and be done with the it. Yea, maybe maintaining bags can be a hassle, but man, for all the money you spend why not.

[@MyCarsandProjects]

@@Justin-il8ij I agree, while they are a cool little feature that provides some benefit, I just can't see spending that kind of money on such a simple items.

[@TheOMEGANOX]

But not available for 3500’s with helper springs?

[@Dmaxstore]

That is correct, you would need to take out the overloads if you wanted to use RAS. Depending on your use case, another type of helper spring may work better for you.

[@jasondmers6791]

Great video fellas very helpful. It did look like to me it could have taken the black shim. Would like to have seen the difference. Follow up video?

[@Dmaxstore]

It could have taken the black shim but Austin does tow very heavy or very often so he opted to keep the smaller shim so it doesn't raise the rear too much unloaded. Maybe we can do a follow up video showing the black shim versus the other.

[@jjsemperfi]

I installed the RAS on my F-150 and wasn’t impressed. Sold the truck and have an F-350 now.

[@christophercarr8717]

Sales guys… we will see if it works 😜 lots of confidence. The mullet helped some but overall just not enough confidence from a couple guys in their 20s.

[@jamesvolpe2186]

Ready Air bags with their air IQ compressor is the way to go.

[@Dmaxstore]

That is also a good set up, we have that on one of our other trucks.

[@leeting8590]

So explain how it works? You haven't mentioned this once. Looks like bad leverage to me.

[@PatrickBaptist]

Thanks for convincing me to just save my money and bag it, there is a reason big trucks run bags and not something like this.

[@BadSSBowtie]

Well, seeing how it didn't change the height difference, I'm out. A lot of money to not buy an add a leaf instead

[@kickapoohiace8747]

Am i the only one here surprised this channel is not sponsored by hair products?

[@Dmaxstore]

Haha! This is too good.

[@adventure_power]

lol you didn't even gave a closer look to let us see. that looked exactly the same

[@michaelcobb1015]

I saw no difference I'm confused

[@AoSC.Arbiter]

Thank you for the effort but, maybe a different video of much less talking and more showing each step of installation instead of just glossing over the steps. Also be more consistent with what you are measuring. Show the measurements before and after. Show different weights too would be nice. Thank you and keep doing what you do.

[@joshuaw2988]

I like how they showed a close up of the tape measure when loaded without their product, but didn’t when installed…….. suspicious

[@davidschlarp1606]

Zero benefit in this. Sag was the same and barely raised it at all. Should of just got a spacer block of ebay for 20 bucks

[@bmahar]

I thought this was a fine and helpful video. Was just about to order this product to reduce sag when towing a camper...but after watching, this product will be a hard pass for me.

[@VulcanAvenger]

Of course the guy who got the suspension for free likes them. Experienced people whom have installed these on several types of trucks and vans would have given a broader viewpoint of benefit of adding these units. An explanation of how overall handling improved, if it did, would have been useful. You have obviously not won people over with this video. Try Harder next time.

[@Lorrieboi]

Gimmick if you’re hauling any notable weight

[@OHVLife]

Well, I just ordered a set of these and then watched this video. I just spent $500 for nothing! This demonstration was not very impressive at all, you gained little to nothing with those things. I guess they could improve the ride while towing but I really need to reduce the squat of a heavy trailer.

[@Dmaxstore]

You can set it onto the heavy setting and it will definitely help. We are doing a follow up video soon. It does improve the ride while unloaded and loaded though even on the light setting.

[@hectorarbelo9965]

I’m not impressed

[@adampark8341]

Typical Chevy droop

[@dojadr4702]

Still got 2.125” of sag…… don’t see how it helped …..

[@Dmaxstore]

We are testing their product and this was on the light load setting, working on a follow up video now for the heavy setting, but it does improve the ride qaulity and control of the load.

[@dojadr4702]

I’m trying to eliminate my wheel camber change when I tow to prevent uneven tire wear so….

[@Dmaxstore]

Send me some more info on your set up and we can probably figure out what’s causing this. [e-mail]
