Heavy gear, a camper, or a plow can bring your front or rear end down and throw your handling off. The Timbren Front or Rear Suspension Enhancement System adds up to 2,000 lbs of load support by using hollow rubber springs that sit above the axle. They work with your factory suspension to keep your vehicle level and stable, improving steering and braking control even when you’re hauling or towing. No air hoses or compressors are needed—just simple bolt-on support that starts working as soon as it’s installed.
Bumpy roads and uneven loads don’t have to mean a rough ride. Each Timbren Aeon spring compresses progressively—the folds collapse first for a soft start, then the stacked shape stiffens as weight increases. This design absorbs road shock and cushions your suspension so you get a smoother, more controlled ride whether you’re loaded heavy or running light. The rubber construction also helps prevent bottoming out on rough terrain, extending the life of your factory suspension.
When curves or crosswinds try to push your ride around, these hollow rubber springs work independently on each side to keep things level. That means less body roll and sway when cornering, swerving, or carrying an off-center load. You’ll feel the difference when the vehicle stays planted through turns and uneven ground.
Installing real load support doesn’t have to be complicated. The Timbren system replaces the factory bump stops with vehicle-specific brackets and includes all the hardware for a clean bolt-on fit—no drilling required. Once mounted above the axle, the springs engage right away to cushion and support your suspension. With durable rubber construction designed for long-term use and a limited lifetime warranty, it’s a straightforward upgrade built for real-world hauling.

Hi everyone. Aiden here with etrailer. Today we're gonna be taking a look at the Timbren Front Suspension Enhancement System. This is going to be an upgraded bump stop for the front end of your vehicle, whether it be a car like the 4Runner here or a motor home. These are gonna come in a variety of different kits and fits with different capacities and help stabilize the front end of your vehicle. Let's check it out.
So why would you be looking for something on the front end of the suspension enhancement side A lot of people are pretty familiar with airbags on the rear axle, and a lot of those suspension enhancement components are used in towing applications or maybe truck beds where you've got really heavy loads in the bed and you need extra support at the back of the vehicle. Now what the front end can do is stabilize that front end, if you do have something like a front mounted hitch, maybe a plow on a truck, or on a larger vehicle or even a smaller vehicle like this, it does help stabilize body roll a lot because these are going to be a lot beefier than the factory suspension and the factory bump stops, that is, and help limit that side to side movement as we're taking turns or driving down in like really windy conditions on the highway. So this will give a significant upgrade for those applications. As far as the construction for these goes it's going to be a hollow Aeon rubber material with a progressive spring rate. Now, what the progressive spring rate means is the more this compresses, the more pressure it has, the more it's going to work at returning the vehicle to its natural position.
So it's just going to resist more and more as it gets further compressed. As for the installation process, this particular one that I've been holding is for the 4Runner, and this one is a very basic kit. It really just has a threaded end with a bolt and a plate on the inside, but this just spreads into a factory weld done on the 4Runner. Very straightforward install. But for all the other different fits and kits, those are gonna have custom brackets and their own hardware that come with it.
So no matter what one you end up going with, if it's a fit for your vehicle, it's going to be custom fit. So the installation should be just a straightforward bolt on process. Now obviously that can vary depending on the kit and what vehicle you're putting it on, especially on the motor home side of things. But for the most part, you should be able to have a very straightforward install process with any of these kits you pick out. And to make sure you find the right kit for you, be sure to enter your vehicle information into our fit guide and use that to narrow down for the custom fit options available for your vehicle.
If you're considering some front suspension enhancement, I do think that these bump stops from Timbren are a really solid option. From the testing we did in installation on our 4Runner, they performed great. They reduced a ton of the body roll and really helped when we're going over speed bumps and just aggressive driving conditions where we need that extra support. Whether you've got a truck with a plow on it, or a motor home that you're trying to reduce body roll on, something like this can be be a huge help and it's a very straightforward solution. But that'll do it for a look at the Timbren Front Suspension Enhancement System Bump Stops. Thanks for watching.

Easy install, great service.
Seams to work fine I have not had any problems with them
One year later, still happy with my Timbrin bump stops. Made some adjustments to my explorer to get the best ride quality , and although I didn't install them for extra load capacity, the Timbrins allow my truck to ride and handle closer to how I want it. Of course, if i do decide to tow or haul something heavy, I've already got it covered.
Thank you
The Timbren springs made a world of difference on my Jeep Wrangler when carrying the plow. No more down in the front or wandering on highway. Great product.
The package arrived in only a few days, sooner than I had expected. I was impressed with Etrailer, the vendor. Opening the brown shipping box however, I was somewhat set off by seeing the Timbren SES box taped up like it went through WW3. It looked like a box that someone had opened once before and someone made an attempt to reseal it with another yard of tape. Opening the SES box confirmed my suspicions that someone had indeed attempted to install these once before and returned them as the 1 paragraph's directions were covered with greasy fingerprints . The parts looked OK so rather than wait for a second pair I just installed them. I have to say that the Timbren supplied written directions left a lot to be desired. I consider myself an above average home mechanic and I had difficulty understanding how to dissassemble the Jeeps front suspension. At the price I paid for these devices, Timbren should at least have made a better effort to create clearer directions. There was no directions on how to get the old bumpers off their perches (they are pressed in . They will only come out using some heat and a lever) , nor how to get the old cups off their perchs (there is one bolts holding each one into the perch, but bolts were so rusty I had to torch them off. I doubt the average Joe would have the knwledge, tools and determination to ge the old ones off). Don't try to do this job without using spring compressors to get the springs out. You'll never do it ! I had to google Timbren installation instructions on the internet to get peoples installation tricks off of a Jeep site. The customer who had this box before me likely gave up due to the complexity of the removal of the old units and likely sent these back to Etrailer (not Etrailer's fault).
I had these installed on my 2013 Jeep Wrangler prior to installing a plow. These fill the gap that would allow the front end to dip when the plow is lifted. I also had them in my 2004 Chevy, they stabilize the front end when the heavy load is added.
