Off-road trails can punish your suspension when the axle hits its limit. These Timbren Active Off-Road Bumpstops use progressive-rate rubber springs that absorb energy instead of delivering a harsh stop. As the axle approaches full travel, the springs engage smoothly to cushion impacts and keep the ride predictable and quiet, even when bottoming out.
When you’re loaded up or hitting uneven terrain, these bumpstops add support that your factory setup can’t match. Rated for 2,000 lbs with a bump load of 4,800 lbs, they keep the rear end steady and soak up road shocks before they reach the chassis. The result is a controlled, stable feel whether you’re crawling over rocks or driving washboard roads.
Factory bumpstops can crumble under repeated off-road stress. Timbren’s design uses a natural rubber compound that stays flexible and tough after years of hard use. The steel brackets and disks are laser cut and finished with a durable powder coat for long-lasting protection against dirt, moisture, and corrosion.
Getting extra suspension control doesn’t require a shop visit. The kit comes with hardware for straightforward installation so you can bolt it up and get back to exploring faster. Once installed, the system works automatically—no maintenance or adjustments needed to keep your suspension working at its best.

Hi everyone. Aiden here with etrailer. Today we're gonna be taking a look at the line of Timbren Active Off-Road Bumpstops. These are gonna have a variety of different vehicle fits and the ones we're looking at today are gonna be for the rear. They also make some fits for the front on certain vehicles so be sure to put your vehicle information into our Fit Guide and get the right set for you because they are gonna have special brackets to fit a variety of different vehicles and be designed specifically for those, but functionally, they're all gonna work in a very similar way. Let's check it out.
Whichever kit you end up going with, generally, this is going to be a very large upgrade to your factory bumpstops. They're typically going to be quite a bit bigger but they're also gonna be stronger. So as you are going off-road or you have a heavy load in the hitch and you need some extra support, this is either going to reduce the movement that your axle has and just help cushion any shock that you're experiencing going down the road, over some bumps or it's just going to provide some extra support so you're not getting such a harsh hit whenever you're going over bumps and don't feel so much shock going down the road. So these are designed with off-road use in mind so it doesn't have to be just towing or with carrying something really heavy in the hitch. Just going off-road and having some extra travel in your suspension going over bumps, these are gonna help provide support and not put so much stress on suspension.
These are gonna have a progressive spring rate and what that really means is the more it compresses the harder it's going to work to help return your vehicle back to its natural ride height. The compound rubber material here is going to be maintenance free, so once they're on you really don't have to worry about them. It's just going to give you some extra support and you don't have to think about airing them up like you would airbags, they're just going to be these. The install process is gonna differ depending on the vehicle you're putting them on. We just did them on this 4Runner and it was really easy.
Overall, they're designed to be a bolt-on installation and will feature brackets to fit your different vehicles and get you the right fit for your own. Now whether you're gonna be using these while towing or with a heavy load in the hitch or just some extra support when you're going off-road to help cushion that axle when it's going up and down and make a smoother ride quality overall, I think it's gonna be a really great addition to the vehicle. For me it's great that they don't have to worry about any maintenance with these. Once they're on, they're good to go and it's gonna give you a lot of upgraded help over your factory bumpstops. And that'll do it for our look at the line of Timbren Active Off-Road Bumpstops.
Thanks for watching.
Ratings & Reviews
Been using the front and rear Timbrens on MY 2020 Nissan Frontier King Cab SV 4x4
Disappointed to find the bracket paint was chipped off in several places. Easy installation. Hopefully performs as advertised.
These do what they're built to do. I overland a lot so when the truck gets weighed down with gear she tends to squat a little and when I go through bumpy areas the factory stops would slam the frame. No any more with these Active Bump Stops. A much smoother ride and less body roll when cornering.
I had no problems with the installation. It only took about 15 minutes to put these on! There is adjustment space on the brackets to let u be able to center product over rear axles. The pictures below show the product installed while my 4 runner is both raised up for installation and after lowering it down. When lowered down and jack removed I have about an inch clearance.
The Product should work out well I think.
Very nice to have somewhat personal service.
Thank you!
Great after sales service , took care of my problem right away without any hassle, very friendly staff
Installation was a breeze! Followed the instructions and lifted the truck up using a jack under my hitch, loosened the u-bolts, removed the factory bump stops and installed the timbrens! Took 5 minutes for each side, and 5 minutes to setup and take down setup. 15 minutes max. Very easy to do. I believe I am going to need a 1” spacer as I have 1.5” Icon add-a-leaf packs in order to get them to engage while towing.
Perfect fit, good quality. Highly recom mend.
I’ve been running the ActiveOffRoad bumpstops on my vehicles for several years and have installed several sets on friends and customers vehicles as well. I highly recommend them as the finishing touch to any performance suspension upgrade, as they reduce any hash bottom-out situations to virtually nothing. Also the SES models greatly improve ride and load capabilities on stock vehicles, also with a much improved ride. Wonderful products!
My 2013 4runner was squatting in the rear when I coupled my 6X12 motorcycle trailer. I was very happy to have found the Timbren bump stop to simply bolt on and fix the problem. However.....during the installation I noticed I had to use ALL of the adjustment slot on the unit to TRY to center on the rear axle. I oriented the units as far towards the rear as the adjustment would allow.
When I coupled my trailer to the 4runner it correctly forced the Timbren bump stop to contact the axle and this is where the problem is.
The Timbren bump stop CAN NOT be adjusted far enough towards the rear to accomplish a centering on the axle. There is a 25% overhang of the bump stop on the axle front. When I communicated with Timbren about this they said" it's a good installation and it's ok". It is not ok.
Imagine that all of the force of a fully loaded truck will be negotiating curves, potholes, swoops and other hazards of the road at highway speeds. All of this stress is distributed on 75% of the product. It can't work as well as if it was 100% distribution. I felt the product was overpriced to begin with. After paying a premium price I expected a custom proper fit.
I can't recommend this product for Toyota 4runner owners.
While towing my boat (2021 Tracker Pro Guide V-175/Mercury 115 ProXS, ~3,200lbs) in my 2021 Toyota 4Runner SR5 Premium, I noticed a significant rear squat. Additionally, fellow motorists would flag me for “high beaming” when I was not. This squatting in the rear raised the front end and subsequent headlight alignment. After much research and review, I purchased the Timbren SES and installed it. With the vehicle hitch unloaded, the SES rides approximately 1.250” above the rear axel. With the boat loaded onto the hitch, the Timbren SES contacts the axel and holds the load firmly, maintaining a level vehicle. I was pleasantly surprised to see that the ride was not greatly effected. Matter of fact, the vehicle rides much better while towing than before installing the SES. With the 3rd row seating in use, and the vehicle full of passengers, the rear passengers complained of a very bumpy ride and I noticed a very rough feel with hard bumps from the rear. After installing the Timbren SES, even with the boat on the hitch and the vehicle fully loaded, my 4Runner remains level and the ride is substantially improved. If you have 3rd row seating and/or plan on towing ANYTHING with your 4Runner, you absolutely need the Timbren SES. Installation is a breeze. Easiest accessory you’ll ever upgrade.
These work really well. Hold a load and still allows for the flex. Perfect combination!
It was easy to install. I will pull a heavy trailer next week for about 500 miles and know better then how well it works.
These installed just like the instructions on your website. I think they will help with hauling loads to the landfill for me. That’s about as off road as I go.
I had these on my Tacoma and liked the way they worked so much that I got a set for my new to me Tundra. You don't notice anything until you put a load on the truck. Then you feel more stable under load and don't have to worry as much about the leaf springs. The install was done in 15 minutes
No issues. Bump stops were easy to install. 10 minutes tops. Etrailer is a great company to order from.
Install on a 2025 Toyota Tacoma TRD Off Road was simple and quick. Transformed the ride quality over large bumps and works great for towing! I’ve run airbags and heavier springs on trucks before and the bump stops are an excellent alternative to both.
So far, they’re excellent. I have a 24’ Taco w/ SuperPacific X1 camper. The bumpstops even out the ride when the rig is full. Great addition. Great Quality. Easy install.
Easy install (2024 Toyota Tacoma TRD Sport 4X4) of the quality Timbren bump stops. Took about 30 minutes, taking my time. Just raises the rear end about six inches with a floor jack and a block of wood, six bolts total. I have not tried towing my camper yet but I did buy some heavy windows and there was no sag. The bump stops are crazily overbuilt compared to the factory (see picture) and are a simple upgrade if you have sag when towing or carry heavy loads in the bed (for reference, the Timbren stops are roughly one inch above my axle when unloaded.)
Makes me want to go hook up my camper just to see where she sits, but I have no doubt that the Timbrens will eliminate any dip in the back. Recommended for build quality, ease of install and economy (compared to air bags or other alternatives)
Made a huge difference on my 5th gen. Have king suspension on it and used with toytec drop kit. Smoothed it out. Should have done this upgrade years ago. Pictures show oem, and timbren compressed on a curb. Even though they are active off-road I’m sure it will help with towing as well. Easy install.
Not sure how I would rate these Timbrens the application would not work on my truck. When installed on my truck, there was not enough clearance brake and other lines on drives side axle to feel comfortable with. Also, the temperance sat approximately 3 1/2 inches off of the axle when truck is in unloaded Did not look like it was going to sit on Timbrens axle flat plate. I believe this is a good product just not a product that’s going to work for me.
I returned the product back to etrailer as of now I have no issues for my refund. Customer service was great to work with no complaints there. Still not decided if I’m going to try something else for pulling our travel trailer.
Super easy to install and they definitely helped with my RV and it's tongue weight. However when I was hauling a load of wood in the back, they were just bump stops, fully compressed. I broke down and replaced them with air bags which are a huge pain to install with all the brackets but they work much better for heavy loads
For the vanilla review but five stars I don't notice the Timbren Off Road Bump Stops since they seem to be doing their job! I have been in the woods and towed our travel trailer with them with zero issues. I went with these verses the the overload type to mimick the OEM stops on my 2019 Ford Ranger. I didn't want to sacrifice rear axle articulation off road so I opted for the shorter stops. All works as it should. My truck doesn't squat any different from the OEMs with the trailer attached and loaded and the ride quality is the same which is what I was going for. Also much cheaper than the OEM replacements and better materials.
If you remove your tire, it's extremely easy to access and install (at least on my 2026 4runner). I took a measurement to my hitch, with no load. It was 19 1/2". Then I attached my rv and with the factory bumpstops, it was 17 1/8". Then after the Timbren install, same load, it was 18 1/8". It reduced the "sag" by 1". Plus, I think the 4runner handles better on bumpy roads and turns.
Install is straight forward. I would note that on my 2025 hybrid I had to cut the tie wraps from the remove wire clip and use my own zip ties. The spacing between tie wraps was far too short to simply move the clip to the new location on the timbren bracket.
