Rough trails can bottom out your suspension fast. Timbren Active Off-Road Bumpstops use a progressive spring rate to absorb axle energy smoothly instead of hitting a hard stop. The natural rubber compound cushions road shocks and softens the jolt at full compression, giving you predictable, quiet axle engagement and disengagement through dips and ruts.
Extra clearance makes all the difference off road. This kit comes with a U-bolt flip setup that moves hardware out of harm’s way for better ground clearance beneath the axle. It’s a clean way to toughen up your rear suspension without hanging low or catching obstacles when climbing over rocks or uneven terrain.
Hauling gear or bouncing through washouts puts stress on your rear suspension. Rated for a standard 2,000 lbs with a 4,800-lb bump load, these bumpstops help manage weight transfer and keep the rear end in control. The stronger-than-OEM rubber construction adds stability when the axle bottoms out so your ride stays composed even with extra gear on board.
You don’t need special tools or a lift to get these on. The Timbren kit installs easily with included hardware and is built from laser-cut steel brackets and powder-coated discs for long life. Once in place, it’s ready for years of off-road use without constant adjustment or maintenance.

Hey guys, it's Jake here with etrailer. Today we've got John with us from Timbren. He's gonna tell us a little bit more about what separates Timbren from the competitors. I appreciate it, I'm glad to be here. Timbren is a suspension specialist. We're based in Whitby, Ontario, so we are a true manufacturer in Canada and we offer a wide range of suspension products from light duty, from commercial all the way up to Overlander, Sprinter applications and trailers.
Now we've talked about a few of the options you guys have and we have plenty of options on our website. Right. We've got the SES kits. We've got the axle-less suspension. Right.
We've got your new coil inserts that just came out recently. But what would you say is your bread-and-butter at Timbren Yeah, no, our SES, suspension enhancement system, is definitely our bread-and-butter. Came out in 2011, won a SEMA New Product Award for best truck suspension. And really, the evolution you just mentioned here, you know, starting in 1968 all the way through now, 2024. But the SES kits are really the core of who we are.
And if you, if you would say at, in the level of stiffness on the market, what would you, would you put yourself in more in a heavy duty side for the SES kits or is it more of a lighter duty Yeah, great question. Lighter duty, we certainly can have a product for commercial and heavy duty, but in '82 when SES was introduced, it was purposely introduced for that, that light duty market. So we start with 1500 and again, go all the way up, but by far really popular with that 1500, 2500 crowd. That kinda leads me into my next question. So we talked about, your specialty is kind of in the lighter duty, but do you have an option for the heavier duty for your sprinter vans and maybe for your truck bed campers Yeah, absolutely.
We do have SES kits for truck beds, truck campers with a higher center of gravity. That creates a new kind of set of problems with the sway side to side. So we have severe duty kits for those. And it uses a single convoluted AON versus a double convoluted to tackle that problem of side to side. And the same thing with the sprinter van. It uses a rectangular shape Aon, but it's there to do the same deal that side to side sway because they're so top heavy, it'll eliminate that. Okay. And then we've had an instance here at etrailer that we had a van that was very, very heavy on the one side. Is there anything that you guys can do personally to help, I would say, I guess customize that kit for that particular user Yeah, by all means we would want that individual to contact us. We would ask a couple questions, see where that weight is distributed and we can actually produce an AON with either a stiffer hardness or durometer or a softer durometer and that will help level it out. So yes, we can take care of that for 'em. And I think that'll really, really help people to get their rigs dialed in because who knows what they're putting in the campers afterwards, after they buy 'em. They come from the manufacturer already heavy on that side and they're trying to load stuff on the other side to try to even it out. But knowing that there's a solution that you can customize for your rig no matter what the weight is on either side is really, really cool. Yeah, absolutely. We're happy to take care of 'em and again, there's no charge for that. Awesome. Now to kind of wrap things up, what sets Timbren apart from a lot of other manufacturers out there Well, I think there's a couple things. We're a family run company and our longevity, you can't deny, 1968 to 2024 and our warranty, we have a lifetime warranty regardless of how old it is. We will take care of it, replace it, limited lifetime warranty, and the hundred day money back guarantee. Very cool. And that's whether or not you're the first owner Right. And yeah, we're not asking for receipt, who'd you buy it from It'll be taken care of. Just give us a ring and we'll take care of it for you. Very cool. Well thank you again for meeting with us. Appreciate it. It was a pleasure to work with you. Thank you.

was advised these would help with sag from load. they make no difference. metal brackets are all chipped up and will be rusty in no tie
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.
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.
Helps keep the truck from squatting when towing my trailer, very easy installation
Great product bolstering the towing capability of the new softer rear coil spring suspension on the Gen 4 Tacoma. BTW, my 2024 Off Road rides great compared to my previous Tacomas.
Bought these for Dad's Toyota TRD off-road to pull his new 3500# camper. They work to soften the load and lessen the squat but there's no space between them and the frame, so they are constantly providing resistance and not letting suspension work before engaging. He's only done short towa with it since, so we'll see how it works over time and when unloaded.
Been using the front and rear Timbrens on MY 2020 Nissan Frontier King Cab SV 4x4
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.
Disappointed to find the bracket paint was chipped off in several places. Easy installation. Hopefully performs as advertised.
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.
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!
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.
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.
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
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.
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.
No issues. Bump stops were easy to install. 10 minutes tops. Etrailer is a great company to order from.
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 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)
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.
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.
