Features to know about

Tackle Rough Trails with Confidence: Progressive Rubber Springs Absorb the Hits

Off-road driving can punish your suspension with hard bottom-outs and bone-rattling jolts. Timbren Active Off-Road Bumpstops use a progressive spring rate that absorbs axle energy instead of stopping it dead. This smooth, predictable engagement cushions road shocks and keeps your ride controlled even when the terrain gets rough. You get the benefit of gentle axle movement without losing traction or composure when the suspension is fully compressed.

Smooth Out Axle Travel: Designed for Maximum Suspension Control

Uneven trails and steep dips can cause harsh impacts that upset steering and handling. These bumpstops are designed to maximize axle travel and provide smooth axle engagement and disengagement. The natural rubber compound cushions each hit, keeping your suspension moving freely while maintaining control. It’s a simple way to keep your rig stable and predictable through every off-road challenge.

Built Strong for Real Off-Road Abuse: Durable Construction That Lasts

Factory bumpstops just can’t handle repeated off-road slams, but these are built tougher. Timbren’s Active Off-Road Bumpstops are made from a superior natural rubber compound that continues to perform after years of trail use. Steel brackets and disks are laser cut and finished with a durable powder coat, giving them lasting protection against dirt, debris, and corrosion. Every component is made to handle the kind of punishment factory parts simply can’t survive.

Quick to Install, Easy to Trust: Hardware Included for Straightforward Setup

Getting better suspension control shouldn’t mean a full day in the garage. The kit includes all required hardware for easy installation, letting you replace your stock bumpstops without extra parts or special tools. Once installed, you’ll have 2,000 lbs of standard weight capacity with a 7,000-lb bump load rating, giving you reliable performance every time you hit the trail.

Video Transcript for All You Need to Know About the Timbren Active Off-Road Bumpstops

Hi everybody, Andy here with etrailer.com. Let's take a brief look together at these Timbren Active Off-Road Bumpstops for your rear axle. Now, these bumpstops have been designed to fit your 2015 and newer Ford F-150, both two and four wheel drive models, and on custom fit parts such as these bumpstops, I do recommend taking advantage of our vehicle fit guide. Simply input the year, make, and model of your vehicle and our fit guide will confirm if this kit will work for you or if we have something comfortable that will work for you. Now, these off-road bumpstops have a capacity of 7,000 pounds and they are going to give you greater control over your Ford's suspension travel. Using progressive rate springs means that instead of a hard stop at the end of the axle travel, the axle energy will be absorbed when bottoming out, giving you a smooth, predictable, and quiet axle engagement and disengagement.

The progressive rubber springs actually absorb the harsh jolt at the end of axle travel, giving you a gentle ride the whole time. So, unlike your factory bumpstops, these Timbren bumpstops are constructed of superior natural rubber compound, ensuring that these bumpstops will continue to operate, even after a lifetime of off-road abuse. And the steel brackets and discs are laser cut before they are painted with a durable, long lasting powder coat finish that's going to ensure protection and a long life. So this is going to be a relatively easy installation. As you can see, the hardware is included.

Everything that you are going to need to install this kit is going to be provided here for you, along with a set of instructions to guide you through that installation process. Now these do have a lifetime warranty from Timbren, and again, as I mentioned at the beginning of our time together, the capacity is up to 7,000 pounds. However, these bumpstops will not increase your Ford's weight carrying capacity. So you wanna make sure that you're not exceeding the manufacturer's recommended weight limit for your vehicle. Well, that's gonna wrap up our brief look today.

I do hope that our time together was helpful for you. Again, my name is Andy. Thank you for joining me.

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.

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:
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.

2024 Toyota Tacoma
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.
by:
2012 Toyota Tundra
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.

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.
by:
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!
by:
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.

by:
2019 Toyota 4Runner
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.

  • Will Timbren Suspension Kit # T28GR Fit 2022 Ford F-150 with Max Tow Package

  • Best SumoSpring Option For 2019 Ford F-150 With 2,000 lb ATV In Bed
    Hello Ron, thanks for reaching out. A 1,500 lb Timbren or SumoSpring would not be enough to support a 2,000 lb ATV in the bed. You would be overloading the springs and would not get the results you want. A really good option for that are the SumoSprings Rebel Custom Helper Springs # SS95QR. These are 3,000 lb capacity which is enough for your ATV. Plus they have a 2-piece design so they don't create a rough ride when you aren't loaded down. The Timbren # TFR1504E would also work for...

    Hey Michael, thanks for reaching out! The Timbren Active Off-Road Bumpstops # T28GR you installed on your 2018 Ford F-150 unfortunately have that reputation among users (although Timbren claims their systems provide a smooth ride). Because of this we typically recommend using the SumoSprings like part # SS95QR instead. The SumoSprings kits do a much better job at providing a comfortable traveling experience. For an air bag kit I do normally prefer the Firestone kits over the Air Lift...
