Here's The Difference Between Bilstein 5100 And Bilstein 4600!!

[@MegaHowtoMan]

4600 are amazing on my 03 Tahoe. Ride on highway is like a modern vehicle. LOVE the reliability of these Tahoes and Suburbans.

[@GOD719]

Yup. I put them on my old k2500 and noticed the difference. I liked them so much i plan on putting bilsteins on my ram. But i want 5100s because i have 35s and a 6" lift

[@shawnwinters4327]

Crapp I just put 5100 on mine they are kind stiff at low speeds but high speed ride good

[@rza380.]

I have a 01 denali a 07 tahoe and a 07 escalade and my 01 denali with 323,000 miles on it and it rides better than both 07 escalade and tahoe

[@TonicofSonic]

I confirmed on the phone with bilstien there is no difference from the 5100 to the 4600 except the 5100 can work on a truck lifted up to 2 inches. Otherwise they perform exactly the same and the 5100 works the same at stock ride height.

[@oldgm8056]

I remember your 5100 installation video like it happened yesterday! 4600 is amazing installed on 2002 Crown Victoria lowred for 4 years and still ride like a new while another brands not stand for more 1 year!

[@ED-ti5tc]

I think 4600 came stock on my 98. When they wore out, i put yellow Monroe on. They were ok. About 10 yr ago i found out AutoZone sold Bilstein. I bought a set for the rear and love them. If i remember correctly, going through AutoZone they have a limited life time warranty. But i love my Bilstein shocks. When i get my front end rebuilt, im putting new Bilstein all the way around.

[@Roberto-gp3yx]

Bc this is not a paid sponsored review … people need to understand that when it comes to a vehicle and its maintenance… no one pays attention to the suspension until they have a catastrophic failure let alone will they pay attention to oil changes and other fluid maintenance So it’s good to see a review based on how one feels their vehicle should be running and the mileage one puts on certain components of their vehicle

[@Green_Leaf]

Great Video. I use the 5100 on my 4WD Frontier with a 2” leveling kit. So far I notice the truck is more reactive to the road.

[@ALMX5DP]

I believe there are some minor valving differences between the 4600 and 5100s. I'm also on a set of mixed and matched Bilsteins 4600s up front and 5100s in the rear (mostly because retailers were out of the 5100s when I was buying the fronts). But they seem to work well together anyways so happy with it as is.

[@RedBeardDevelopment]

A lot of people run 5100s in the rear for towing, you've got a good combo there.

[@blackericdenice]

I have a 2004 Trailblazer 256 with 196k miles. I bought it used in 2008 with 65k miles. It still has the Bilstein shocks it came with. I think it's time for new shocks. You video has been very helpful.

[@DirtE30]

Both fantastic shocks. Different valveving slightly. The other issue is the stock ride height of a lift capable shock. May have been bottoming the 5100’s at times.

[@zachprice3279]

Yes the 5100's have slightly stiffer damping from what I've read. As far as bottoming out it would at least depend on the vehicle I believe. I just put 5100s on my truck 2 days ago. Its a stock height 2016 Ram 2500. The collapsed length of the 5100 is only like 0.13" longer so I'm certain it would still hit bump stops before bottoming the shock. Very pleased with the ride improvement on bigger bumps on the highway and speed bumps in parking lots.

[@JoshDurston]

Both the 4600 and 5100 come in a variety of lengths. Big plus for the 4600 is the paint is much more rust resistant than the zinc coating on the 5100. Note that OEM Bilsteins are not the same as aftermarket even if they have the same looks and yellow paint. OEM shocks have the vendors' specific valving (probably softer), aftermarket has the Bilstein (probably stiffer) valving.

[@warrenlucier5796]

The 5100's are more for off road, like out on a ranch etc. . The 4600's are made for paved roads and I had them on my 1996 Ford F150 with a towing package and my current Toyota Tacoma.

[@steviegenoski9977]

yep

[@stickbeard]

Nope. Call Bilstein and talk to them. The 4600 and the 5100 are the exact same on the inside with the exception that the 5100 are make for up to 2 inches of lift. If you are stock height, save your money and just get the 4600s. The 5100s will also work, but you are paying for something you won't be using. And the 5100s look different on the outside. I think the shocks were just worn out on the vehicle.

[@steviegenoski9977]

@@stickbeard I'm maxing out the 5100s to the 7th ring position in front and adding a 1 inch spring lift in the rear. I'm shooting for 3 inches of lift. I won't be running 35s but I will be close at 34 inch tires. This is more for a lift than anything, I just don't want to use spacers. I'll change the control arms and linkage also.

[@rondogwil]

I had a full set of 4600s on my 97 F250 HD for about 20 years before I noticed a rear leaking. I replaced the rears with new 4600s. Then I noticed the front bouncing down the road with my slide in truck camper on the back. So I replaced the fronts with new 4600s. I figured if the first set lasted 20 years, that was reason enough to buy them again.

[@SuperDuty23XL]

Plan on replacing my stock shocks on my F350 with 4600s. great video.

[@toyotabrony]

@1ROAD there’s nothing wrong of swapping g from 5100 to 4600. It’s still an upgrade monotube shock absorbers. Honestly Bilstein B6/4600 is still a must have shocks. 2: When are u gonna upgrade ur front 3157 turn signals, ur rear 3156 turn signals with sylvania zevo amber , and a Novita - LED flasher relay, and a Sylvania - zevo 3157 red led bulbs for ur 03’ Chevy suburban?

[@douglasdever6134]

The 5100s are used more in the front with the spring perch, that has a coil spring mounted, allowing for adjustablity to give a 1-2" (or more) lift to the vehicle. Your system uses torsion bars so adjustable shocks are not needed. Honestly, should have gone with the 4600 the first time around and would have save a few bucks. Like you said, internally, basically the same single tube, gas filled, digressive valve shock. The 5100s are zinc coated steel, while the 4600s are painted. And the paint can wear off just as quick as the zinc can look dirty. Also, the 5100s are longer since they tend to be used with vehicles that have been lifted. If you crank your torsion bars to lift the front end, you might have needed the 5100s; not having lifted the front end makes the 5100 appear to be too long. But in some cases, length only matters at certain times.

[@aportilla007]

I recently put 4600 on a 99 Jeep TJ. I also put in an OME steering stabilizer. The Jeep rides awesome.

[@corail53]

they are the exact same shock - the 5100 is designed for slightly lifted vehicles while the 4600 is designed for oem spec. Internally they are the exact same.

The 5100s are meant to be less stiff. My truck came stock with the 4600s. I was off-road a lot so I wanted something with a little bit more cush. So I swapped to the 5100s and it helped a lot.

Same with a 84 1 ton Chevrolet van put Monroe Magnums on it(again money problems but it cost me more in the long run), yeah they were just barely better than the blown ones, 30 ft Class c motorhome on a Ford chassis that was the biggest difference right there. So when I'm getting at is save your money and get the Bilsteins from the get-go.

[@jewllake]

I think the blue AC Delco shocks are the best. I replaced mine on my 2006 GMC Yukon 4x4 with over 140K miles a few months back. They felt very stiff when pushing down and came back up smoothly. I sold them of facebook market place for 60.00. I used the 4600 and I opted to buy the bushings from GM as they are beefier and include a heavy nylon sleeve to help eat up that very large hole on the top frame mount. I still have the stock Nivomat self leveling shocks in the rear. I do have the 5100 on my 2018 Z71 Crew Cab Sierra.

Great stuff Jimmy! I'm at that point with my Suburban. I've replaced the fronts before but not with the original Billsteins. The rear are still original if you can believe that and still have that iconic blue and yellow look to them. I remember when you put those 5100's on and thought I needed to also but, thanks to this video (like many others) I think I'll stick with the 4600's. Thanks for sharing and I can't wait to see what's next.

[@omorin34]

I run my 2018 ram 2500 with 2" lift Thuren springs and 2007 4600 shocks. The previous version ran longer shocks, well in the front. The spring shock combo is like butter.

[@AbdiasGarcia21]

The 5100's are valved with softer compression and rebound curves for offroad comfort and less wheel hop on grave, dirt, or wash board surfaces. Compared to the 4600's valved with higher compression and rebound curves for on-road and highway driving that requires more overall damping response to control the springs and bounce at high speeds. This is a great video with real life samples. I wish modern Chevy's Z71 package was built on the 4600's not the Ranchos as they are even softer than a 5100.

[@charliedee9276]

5100's on my 4" lifted Grand Cherokee, great shocks!

Fronts have the engine sitting on them, so they'll wear more. Bilstein makes a great shock. I have 4600s.

The 5100s on my 13 F150 are adjustable by moving a snap ring. I used them to level my truck and handle an A/T tire. Even they I went up 2" plus a bigger tire, bory roll was reduced.

[@cowboybootshatsandwesternl9663]

I have my 2015 jeep grand Cherokee that is lifted with the aid of the 5100 leveling shocks and they have been great. I also have a 2003 Dodge Ram 3500 Dually that is leveled with 2 inch springs in the front and I have skyjacker shocks that are doing fine in the rear but are leaking in the front after only 6 months. Unfortunately they do not have the 5100s available for my truck but was wondering if the 4600 would be ok even if the front is leveled.

[@artm6723]

Easiest way to figure out if you need new shocks is the bounce test. Just push down on the front (or rear) of your vehicle a few times then step back. If it continues to bounce up and down more than a couple of times you probably need new shocks. Good shocks should be able to stabilize your vehicle rather quickly. Worn shocks won't.

[@nastysoda9212]

that's what my trd-offroad tacoma has stock. they do great off-road and great on road. I have another tacoma with 6112's and 5160's in the rear. And prefer driving on the 4600

[@ElectricBlueIX]

I removed the mag ride shocks on my 17 Yukon and went with a pretty cheap set and have not been happy with them at all. The ride is very floaty and doesn’t feel under control, especially when we are loaded down with all our gear for a trip. The other thing I can’t stand is that they don’t feel like they soak up any of the bumps. Everything transfers into the truck. One last thing, the ride height. In the front it was a strut assembly and the company said the ride height would be basically level but it’s not. The front springs never settled so it’s squatting while driving, which I hate. After watching this video I’ll be swapping out to the 4600’s in the front and going back with air ride in the rear.

[@JacobZwerner]

Do you have the torsion keys in with the 4600’s? Did you need a spacer on the front?

[@rototiller78]

Love my 5100s on my '07 Lincoln Mark LT in which the 4600s would fit too. Also, the Bilstein company recommends the "boot" side bolted to the wheel side.

[@WalterMelons]

Wonder if it’s because gravity would help keep debris from working into the cylinder if the boot failed.

[@stephenmonroe7541]

Front shocks on those GMs only install one way.

[@TurtlDrip]

You can't flip the shocks to the boot side down on the front of this truck. Different mounts on each end

[@rototiller78]

Well, thanks @stephenmonroe7541 @don_moody for the GM clarification as I am familiar with Ford and Honda. Why would Bilstein want their shocks installed boot side down if they couldn't be? 🤔🤦‍♂️

[@jmackinjersey1]

Front suspension and brake components always take more of a beating when compared to the rear components due to the heavy engine as well as braking process as well as hitting holes and other issues with the pavement harder than the rear.

[@JG-yd8so]

Are your coil springs the same age on both vehicles? They do start to sag over time, transferring more work load to shocks, thus reducing efficiency/longevity. 5100s have a lifetime expectancy of 50K miles

One more bit of info, when an OEM has a name brand component on their vehicle, like a Rancho, Bilstein or even Fox shocks or say an upgraded brake system, those components are not the same that you will buy from an aftermarket dealer with the same name on the side of the box, even if it has the same number/nomenclature on the product or box. Typically the aftermarket is even better than the one from the assembly line.

[@DanBrando]

Are you sure with these?? What about Toyota tacomas wit these? Do you know for sure?

[@sirhcmi3]

I'm pretty sure the 4600's have a different loading profile. It's been a while but I went through the same journey years ago. The 4600's have a soft start and damp progressively firmer as they compress (progressive?). The 5600's have a firm start then soften a bit (digressive?)... Regardless of why. I like the 4600's more also. (02 Avalanche 1500)

[@eugeneshackelford9112]

The two is designed for two very different ride and control. You can't make a judgment on pushing in on them because of course they are going to react differently.

U get what u paid for. Remember. Quality isn’t cheap, and cheap isn’t quality.

[@r0ckworthy]

Do automotive shocks generally have a stack of shims inside? Like a dirt bike shock does. For instance are automotive shocks like the Bilstein 4600 a "cartridge type" shock or are they all the old-school type with just a damping rod with oil holes in it? Because on a dirt bike the old damping rod shocks are absolutely terrible and once you feel the difference of the cartridge design, the difference is obvious.

its because the 4600s are a higher pressure shock, so less shockfade but also a stiffer ride quality, the 4600s also have less hydrolic fluid so if your going off-road and flexing the suspension a whole lot, the 4600s could overheat and wear out faster on the trails

[@mikemcf9189]

You keep talking about FADE. I do not think you know what this means. "Fade" is from heat during heavy use and is why high-end off-road trucks have shocks with external reservoirs and baja truck shocks have radiators. Sure, they'll wear out over time but that has nothing to do with the "Fade" that you read about on the 4600 brochure.

[@cgriebel1]

Correct. Fade also corresponds with stroke/frequency. Short stroke shock shafts, as in the case of a auto/truck shock, don't really heat up the shock like a full-on off road vehicle (think trophy truck or motocross), where the stroke can be as much as a few inches both ways for mx or wayyy more for a trophy truck. Hence the piggy-back reservoirs to store more fluid and aid in cooling. The fluid in those shocks takes a beating, and is changed out regularly.

[@GutterCleanerResourceUSA]

Great video . I think the 4600 is for trucks that are not lifted.

[@jameshall4385]

The longer shocks are designed for a taller vehicle. They are probably compressed to much and not able to work as they are designed to for a suspension with more travel

Aren't the 4600s for stock lift height and 5100s require 2-4 inch lift rear and 4-6 inch front. That's how they are for my 1997 suburban.

Clear coating when they are new will keep the nice

[@KG5DGO]

I thought the Bilstein shocks were lifetime warranty?

[@jmackinjersey1]

5100s are Zinc coated as opposed to paint on the 4600s. Zinc tends to last longer where salt/sand/mud is prevalent. Yes, the 5100s are typically used on trucks or Jeeps with an aftermarket lift. They are also valved just a slight but stiffer to handle the lift and weight of the taller tires/wheels/lift kit etc. The 4600s are what OEMs use when they choose a stock ride height, but want to add Bilsteins to a package, and are the same as a stock shock when it comes to ride and comfort.

Excellent !

[@alanmerritt860]

For the price of them they should last a lot longer than 2 years. Also try sos pads on the other shocks to shine them up

[@toyotabrony]

Maybe he was on stock height with 5100, and overtime that can compress a bit too soon.

It’s been 5yrs. I’m happy with that length of time. 🤙

[@stephenmras8519]

5100s are for a 2” lift. They are longer and will bottom out on a truck that is not lifted. Been there and done that. Have a set of 5100s with 3K miles on them for sale.

[@brandonbanuelos953]

Damn i just bought the 5100 for my suburban thinking they were better but now im regretting my choice

[@NiteHawk861]

Nice Tahoe!

[@autoshaman4319]

Here's what I. Will say bill steins are awesome.I love them but As far as the back goes throw a set of nivomats on there and you will never look back. They are self-adjusting and they hold the back of a suburban planted like no other shock, not even a bilstein, will compare.

[@bullheimer]

those are supposed to be matched to nivomat springs. did you do this. and, they are coil springs. anybody have any idea if these shocks would work with a leaf spring rear vehicle?

[@autoshaman4319]

@@bullheimer I used precision HD 1/2 ton springs and nivomat shocks.

[@autoshaman4319]

Also Arnott makes a front replacment shock that is stouter than the bilstiens

[@trooperpol]

Maybe if you don’t cranked up the torsion bar the 5100 works shorter than they must. If you lift the suspension the story will be different

[@blakeharden4528]

anyone know where i can buy 5100’s?
