When the terrain gets rough and the suspension reaches full travel, these Timbren Active Off-Road Bumpstops step in to take the hit. The progressive spring rate absorbs energy instead of slamming to a hard stop, keeping axle engagement and disengagement smooth and predictable. With up to 1,000 lbs of front suspension support and a bump load rating of 1,800 lbs, they cushion harsh impacts so you can stay in control through ruts, rocks, and washboard trails.
Factory bumpstops can wear out fast under constant off-road use. Timbren’s Active Off-Road Bumpstops are built from a superior natural rubber compound that holds up after years of abuse. The rubber’s flexibility lets it absorb repeated hits without breaking down, so your front suspension keeps its performance and protection even after miles of tough terrain.
Durability starts with solid hardware. Each steel bracket and disk is laser cut for precision, then finished with a long-lasting powder coat to fight corrosion and wear. That combination gives you a setup that’s strong enough for off-road punishment while staying protected against rust and road debris.
You don’t need special tools or a lift to get these working. The kit includes all the hardware you need for easy bolt-on installation. Once mounted, they’re always ready—no air lines or adjustments required—just smooth suspension control every time your shocks bottom out.

Hi everyone, Aidan here at etrailer. Today, we're gonna be taking a look at these Timbren Active Off-Road Suspension Enhancement System Bumpstops. These are gonna come in a variety of different fits and kits for various different vehicles, so be sure to check the fit guide and find the right kit for you. But let's check out the whole line and see how they work. So these bumpstops are designed to be a custom fit application for the front end of whatever vehicle you put them on. We just finished installing them on the 4Runner here, and it just dropped in place where the original factory bumpstops were.
These ones are a fair bit bigger, not completely huge, but still an upgrade from the factory ones, giving us enough room for some movement and travel, but offering more support for off-road applications and increased support for things like body roll. Now, depending on what you're looking for, you might consider a set of these for the rear. Those are often used for towing applications or we've got tongue weight on the vehicle or a load in our truck bed where there's maybe some sag back there. So if that's more what you're looking for, use our fit guide to find the right kit for you on the rear axle, but for the front end, this is what you can expect, and it's mainly going to be targeting the driving performance. These are going to be constructed with a natural rubber compound and come with all the pieces you need to get set up.
Pretty much all of them are gonna be designed to be a custom bolt-on application with little to no drilling required. Now, obviously, that's going to depend based on whatever kit you go with, the installation process will be a little bit different. For the 4Runner ones here, it was really just threading it directly into a factory weld nut, and in the case of that factory weld nut being broken or not operational anymore, they do include a nut with the kit in case you need it. And while Timbren does offer these Active Off-Road Bumpstops that are designed to give you a little bit more travel and maybe be better for off-road applications, they do offer other kits that are just their standard suspension enhancement system. Now, again, depending on what kit and vehicle fit you go for, it might be a little bit different, but for the most part, it should be a little bit bigger and be more targeted towards just increasing the overall ride quality of your vehicle when you're driving.
So in the case of these 4Runner ones, they make quicker contact and help a lot more with body roll. Even though they don't give as much room for travel, they will offer a great amount of support, especially over the factory bumpstops. And with these springs, I do wanna mention, it uses a progressive spring rate, so the more that they compress, the more they're going to push back and try to return the vehicle to its natural driving state. So as it compresses more, it is going to offer more support where it's needed. And that's really all there is to it, it really just comes down to finding the right kit for your vehicle, and then, getting them installed.
That installation process is gonna vary depending on which kit you go with, so be sure to check our website, see if they have any install videos to follow along with, but for the most part, they're very straightforward, it's just a bolt on installation. But that'll do it for a look at this line of Timbren Active Off-Road Bumpstops. Thanks for watching.
Ratings & Reviews
Easy install, work great.
the bumpstops are good
but the real winner is Etrailer.com fantastic customer service.
I installed these on my 2016 Colorado to cushion/limit front end squat with my snow plow installed. Work perfect with plow weight, don't touch when plow is off.
My 100 series 2001 Toyota Land cruiser uses four of these bump stops though the build quality of this product is excellent I am only giving it an average rating because 2 of the metal housing that the rubber sits in widens up at the bottom edge. I had to cut that edge back so that they would not scrape one on each side.
Disappointed in this item TABSTOF. They look and feel almost exactly like the factory bump stops, except with a hole drilled in the center. I can't imagine these would make much of any difference in rebound cushioning as there is just not much to them. There is another part which is more appropriate TOFTAC4A, which are larger and would actually have a benefit whether in a standard or lifted suspension.
I like the way they worked ,, but unfortunely I traded that vehicle in , hope somebody is enjoying the comfort ride
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
These are way better than the stock rocks!! I’m glad I invested in these. No regrets!
can not say that they made a change in my over all suspension handling so i would say that to me it was not worth it but then some one else may like them
Bought these in lieu of airbags for my Nissan Frontier. I overland in the desert, taking Astro pictures. I put in Bilstein shocks, raised it about an inch (I’m 5’2, so any higher and I can’t get in my truck!). . Even going as light as possible with my RTT, rack, and other equipment, I was still bottoming out in larger ruts. Everyone suggested airbags but I didn’t want to have to maintain and adjust them. These are perfect and have fixed that problem.
These bumpstops are excellent! they look better in person than they do in the picture. Because I have a 2" spacer lift on my Frontier Pro4X, I needed to Timbren 1/2" spacers & longer 2" bolts. I tested these under full flex and they work perfectly.

The front bumpstops required a 12 spacer to compensate for the 2 lift on my truck. These have been working great! Much improved ride quality when suspension bottoms out.
