When a load or trailer drags your front or rear end down, these 3,500-lb-capacity Timbren Active Off-Road Bumpstops keep things level. The hollow rubber springs sit right above the axle to stabilize and support your suspension so sag and sway are kept in check. They take the brunt of the weight and help your steering, braking, and headlight aim stay consistent even when the load gets serious.
Rough pavement and washboard backroads can rattle everything loose. Timbren’s Aeon hollow rubber springs absorb road shock to give a smoother, more stable ride when loaded. The progressive design collapses along its folds as weight builds, then stiffens to provide extra resistance right when you need it. That cushioning protects your suspension from bottoming out and cuts down on bounce over uneven ground.
Each hollow rubber spring works on its own side of the vehicle, which means better control through turns or when carrying uneven loads. When one side compresses, the other stays steady, reducing body roll and keeping you planted whether you’re swerving around a curve or hauling something off balance.
These bumpstops bolt directly onto the frame using the included vehicle-specific brackets and hardware—no air hoses, compressors, or manual adjustments needed. Once installed, they immediately start working with your factory suspension to add support every time you hit the road. It’s an easy way to extend suspension life and keep your ride level without worrying about leaks or upkeep.

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.
