Timbren Vehicle Suspension - TABSJRJK

Highlights

  • Custom Fit for Your Vehicle: Mounts to existing attachment points
  • Smoother Off-Road Ride: Progressive rubber springs absorb harsh jolts for steady control on rugged terrain.
  • 3,500-lb Load Support: Helps the rear suspension handle weight smoothly while maintaining better stability.
  • Stronger Than OEM Bumpstops: Natural rubber compound resists wear and keeps working after years of off-road use.
  • Quieter Suspension Travel: Cushions axle engagement and disengagement for a calm, predictable ride.
  • Quick DIY Install: Bolts on easily with included hardware for a fast upgrade to rear suspension performance.

Features to know about

Smooth Out the Rough Stuff: Progressive Spring Rate for Off-Road Control

When trails get rough or the suspension reaches full travel, a hard stop can jolt the whole ride. The Timbren Active Off-Road Bumpstops use a progressive spring rate that absorbs energy at the end of axle travel instead of slamming to a stop. Axle engagement and disengagement stay smooth and predictable, so you keep better control without harsh impacts when bottoming out.

Take the Hit, Not the Damage: Strong Natural Rubber Construction

Factory bumpstops can compress too easily or crack under abuse. These bumpstops are built from a superior natural rubber compound that holds up through years of off-road hits and suspension flex. The material cushions road shocks, so your suspension components take less strain while still feeling controlled and responsive.

Built to Last Every Mile: Laser-Cut Steel Brackets and Powder Coat Finish

Off-road conditions beat up metal parts fast, but these mounts are designed to last. The steel brackets and disks are laser cut for precision fit and then painted with a durable powder coat finish to resist wear and corrosion. They’re ready for long-term use without giving in to rust or rough terrain.

Simple Setup That Fits Right: Hardware Included for Easy Installation

Getting better suspension performance shouldn’t take all weekend. The Active Off-Road Bumpstops come with all necessary hardware, so installation is straightforward. Once bolted up, you’ve got 3,500 lbs of standard weight capacity with bump load support up to 9,500 lbs, giving your suspension a serious upgrade while keeping setup simple.

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.

I'm glad you were able to make it work even with the zip ties being too close together when trying to relocate them to make space for the bracket. What are you planning on towing with your Maverick?

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.

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.
by:
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
by:
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.

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.

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)

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.

I have them on my 4th Gen Toyota. Have an Wedge Camper and can go backcountry with 600 lbs or more in the back. The Timbren Active Off-Road Bumpstops helped tons just last weekend while 4x4ing grinding out up old minning roads and camping in eastern CaliforniaNevada. Saved use numerous times form bottomming out hard. Very satisfied.

@Tb Sounds like a great time Tb! The last time I was out in California visiting friends and family, my buddies and I took an old Suburban out in the Mojave desert, after driving in the ice and snow here in Missouri I did not hold back, it was a blast! Glad to hear we had the right fit for you not to bottom out. Where are you headed for the next adventure?

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.

No issues. Bump stops were easy to install. 10 minutes tops. Etrailer is a great company to order from.

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

I pull a 20 ft car hauler with the Tundra and recently hauled a car to Arizona then hauled another back. The frame just touches the top of the Timbren when loaded. After 3,000 miles of driving I am even more convinced that this is a great product. The truck never squats from trailer load and the Timbren also keeps the ride smooth straight and steady when pulling a load. When unloaded there is about a one inch gap between the frame and the Timbren so it drives like stock when lightly loaded or unloaded.

by:
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.

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.

These work really well. Hold a load and still allows for the flex. Perfect combination!

2013 Toyota 4Runner
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.

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!

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.

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.

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.

  • Recommendation to Reduce Rear Sag on 2018 Jeep JL Wrangler When Towing Trailer
    The Timbren Active Off-Road Bumpstops # TABSJRJK referenced in your question are confirmed to fit your 2018 Jeep JL Wrangler Unlimited. These are designed to replace the factory bump stops on your Jeep and will provide a stronger unit that will do a better job of supporting the rear suspension and absorbing energy and cushioning road shock. These should definitely help a bit with the rear sag on your Jeep when hooking up to a trailer, but it's not your best option. When rear sag on a vehicle...

    The Timbren Active Off-Road Bumpstops - Rear Suspension - 2,000 lbs # TABSTORSEQ are not designed for your 2016 Jeep Wrangler Unlimited. You will instead want the Timbren Active Off-Road Bumpstops - Rear Suspension - 2,400 lbs # TABSJRJK which are a confirmed fit for your vehicle. They measure 3-5/8 inches tall as you can see in the attached photo.

  • Recommended Timbren Rear Suspension Enhancement for 2015 Jeep Wrangler Unlimited with 4
    We have spacers that you can add to accommodate a 4" lift on your 2015 Jeep Wrangler Unlimited, but there are no Timbren kits available that come preset for a 4" lift. If your Wrangler Unlimited is a 4WD then I recommend going with the Timbren Rear Suspension Enhancement System # TJRJK. If you have a 2WD then you will want the part # TABSJRJK instead. You can accommodate your lift by choosing a combination of the following spacers for raised frame vehicles: 3/8" Bushing 1/2" Spacer -...

  • Recommended Suspension Enhancement to Reduce Sag on 2018 Jeep Wrangler JL
    For the rear sag on your 2018 Jeep Wrangler JL, I recommend the Timbren Active Off-Road Bumpstops - Rear Suspension - 2,400 lbs # TABSJRJK does not allow for spacers so it won't reduce your sag much. My recommendation that will allow adjustment to fill the space and reduce sag is the Air Lift AirLift 1000 Air Helper Springs for Coil Springs - Rear # AL60829. If you want the compressor for adjustability at anytime you can use # AL25980.

  • Compatibility of AirLift 1000 Air Helper Springs on 2017 Jeep Wrangler Unlimited with 2 Inch Lift
    The Air Lift AirLift 1000 Air Helper Springs for Coil Springs # AL60817 are not a fit for a 2 inch lift if it included aftermarket springs. I reached out to the manufacturer and they would need to know the inner diameter and length of your springs to fit with another air bag system. However, if your height has not been altered by replacing the springs or mounts and instead has been lifted in another way, then the Air Lift kit listed above will work. Another option is the Timbren Active...

  • Jounce Spring Suspension Recommendation for Off-Road Towing with a 2023 Jeep Wrangler
    Hey Wade, thanks for reaching out! I recommend checking out the Timbren Active Off-Road Bumpstops # TABSJRJK for your daughter's 2023 Jeep Wrangler. The overall height of this kit is 3-1/2" according to Timbren, and although they may not be significantly longer than your OEM bumpstop, these are definitely more rigid so you'll get more help there.

  • 2018 Jeep Rubicon Unlimited Suspension Enhancement Recommendation
    The Timbren suspension kit part # TABSJRJK that you referenced would be the correct enhancement kit for your 2018 Jeep Rubicon Unlimited but since you also have a lift kit you'll need spacers: 1/2" Spacer - # TA25722-90F00 1" Spacer - # TA25723-90AD00 Since you have a 2.5 inch lift you'll need 2 one inch spacers and a 1/2 inch spacer per side.
