  • Timbren

Replace your rear factory bumpstops and enjoy greater control over your vehicle suspension when travelling off-road.

  • Progressive spring rate

Timbren's Active Off-Road Bumpstops provide off-road enthusiasts with greater control over their vehicle's suspension travel. Using progressive-rate springs means that instead of a hard stop at the end of axle travel, the axle energy will be absorbed when bottoming out, producing smooth, predictable, and quiet axle engagement and disengagement. The progressive rubber springs absorb the harsh jolt at the end of axle travel, giving you a gentle ride the whole time.


Unlike your factory bumpstops, Timbren's bumpstops are constructed of a superior natural rubber compound, ensuring the bumpstops will continue to operate even after a lifetime of off-road abuse. And the steel brackets and disks are lazer cut before they are painted with a durable, long-lasting powder coat finish to ensure protection and long life.

Video Transcript for Review of Timbren Vehicle Suspension - Active Off Road Bumpstops Rear Axle - T28GR

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.

These definitely do the job in my xterra whether it’s hooking up a heavy trailer or just stopping the bottoming out these vehicles can experience. Easy install would recommend 100%



by:

Can't wait to pull my RV trailer again and see less squat in the backend of my Raptor!! These are going to make a difference.



by:

Ordered for my 2010 Toyota Tundra. Parts came quickly and had them installed in about 20 minutes. Just needed a good vehicle jack and impact wrench and was very easy. These have greatly reduced the sag when pulling my camper and very satisfied.



by:

The factory bump stops were harsh. These engage sooner and while firm they do not crash like the OEM.
Easy install.



by:

Very easy to install, haven't traveled with trailer yet but will be traveling in April.



by:

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.

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.



by:

Easy install, Nissan Xterra. Love that it came with all the hardware because I had to knock all existing hardware out with a hammer and chisel. I used four additional washers I had so I could put one inside the frame and one on the bumpstop mount. Etrailer shipped fast and free, bumpstops arrived ahead of schedule. Highly recommend these mounts, night and day difference.



by:

They work well towing a heavey trailer.



by:

Well after used the Chat online with Carol I ordered. Paid for 2 day shipping. Got it in 2 days.

Total install time 1 hour.



by:

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



by:

They seem to perform just fine, absorbing bumps and impacts etc. However they collect water like little buckets and the bolts are clearly corroding on the inside of the bumpstops since they have no drainage. Adding a way for water to escape faster than evaporation would be a good improvement to the product!



by:

Work great, save my air bags from getting pinched if I let them get deflated.



by:

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:

Fit was well, but had some paint chipped off from transit.



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:

easy to install - might want to let installers know you don't need to remove rear tires or jack the vehicle up (safety first!) on the Tundra. Just remove the 3 oem 12mm bolts on each side and replace the itty-bitty oem bump stops with your nice Timbren's (17mm bolt head and nut).



by:

I Install this product on the front and back of my 1994 toyota land cruiser ,I realy like them , we explore the Baja peninsula in MEXICO the off road land is very ruff , this bumpstop realy work . the don't crash in to my diferencial any more



by:

I have had Timbrens on several trucks! I always thought they worked great! I plan on putting these on a new Tacoma, which I will not yet until the end of September so I hope they fit! They are a very good product otherwise I would not use them!



by:

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.



by:

Very effective upgrade and install wasn’t to bad either. Highly recommended! 2003 Toyota Tundra.



by:

Very easy to install.



by:

It only took less then 30 minutes to install, What a big improvement!! Installed on a 2022 Toyota Tacoma Off Road, towing a 2018 Coachman Ultra Lite, 5900 lbs.



by:

These bump stops are amazing, the ensure any contact made with the axle is hardly noticeable. I highly recommend these if your stock bump stops are just rubber covered steel blocks like the ones on my Xterra were.



by:

Fast shipping! Product as described.

  • Air Bag Kit Recommendation for 5th Wheel Towing with a 2018 Ford F-150
    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...
