Upgrade your vehicle's suspension with hollow rubber springs that absorb shock, minimize sag, and boost stability. Whether hauling gear or towing a trailer, enjoy better handling and a smoother ride with zero maintenance.


A full truck bed shouldn't mean poor handling and bottoming out. These springs reduce sag, making sure your truck stays level while improving steering and braking, whether you're hauling lumber, tools, or gear for your next trip.

Towing a fully loaded trailer can make your vehicle feel like its floating. These suspension springs help keep everything steady by minimizing sway and keeping your vehicle level, so you stay in control when hauling campers, boats, or work trailers.

Uneven terrain and bumpy roads can make for a rough ride, especially when towing or hauling. These rubber springs absorb road shock, reducing the impact on your truck and trailer for a more stable and comfortable drive. By cushioning the jolts and vibrations, they also help protect your trucks suspension components from excessive wear and tear, extending the life of your shocks and leaf springs.

When you're taking a sharp turn or carrying uneven loads, these springs work independently to keep your truck stable. Whether swerving to avoid an obstacle or hauling an off-center load, you'll feel more secure behind the wheel.

Airbags need constant monitoring and adjustments. These rubber springs just install and do their job - no compressors, hoses, or pressure checks required. You get consistent, hassle-free suspension support every time you tow or haul.

Hi everybody. Andy here with etrailer.com. Let's take a real quick look at this Timbren rear axle suspension enhancement system. Now, these springs have been designed to fit your 2017 and newer Chevrolet Colorado 4 wheel drive and on custom fit parts such as these springs, I do recommend taking advantage of our Vehicle Fit Guide here at etrailer.com. Simply input the year, make, and model of your vehicle and any other questions that it might have, and our Fit Guide will confirm if this will work for you or if we have something comparable that will work for you. These hollow rubber springs have a capacity of 6,000 pounds and they're gonna mount to existing attachment points on your Colorado to give you strong rear axle support, to help reduce sag and improve handling.
Now, these springs are also going to give you additional support as needed, so you always have a smooth, comfortable ride allowing your leaf springs ample movement while cushioning light loads. And they're going to ride just as smoothly when you're not hauling a load. They become more rigid as more weight is added for greater performance when you're hauling a heavy load, increasing stability and reducing vehicle sag. They work independently, adjusting side-to-side, helping to compensate for off-center loads and reducing body roll when swerving and turning corners. These springs also act as shock absorbers, taking the brunt of bumps on rough roads, extending the life of your vehicle suspension.
So this kit does include everything that you see here. You're gonna get these two hollow rubber springs, vehicle specific brackets that, again, are designed for your Colorado. And then the bolts here are going to run through the springs to mount through the spacer and the heart, the bracket, here. So everything that you're gonna need to get these installed in place, along with instructions to guide you through that installation process. Again, the capacity is 6,000 pounds, but it is important to note that these Timbren springs do not actually increase your Colorado's weight carrying capacity, so you wanna be sure that you don't exceed the manufacturer's recommended weight limit.
Now if you do decide that these are going to be exactly what you need, that's great. Once you get these installed, we would love to hear back from you regarding your experience with them, and you can share your experience with us by dropping a comment or leaving a review on this product page. And if you leave a review, you can also send us some photos as well, showing us these in operation and letting us know how they're working out for you. We'd love to hear back from you. Well, I think that's gonna wrap up our look today.
I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me.

Got them in yesterday took about 30 minutes to install hook up my travel trailer it help a lot I'm very please. Troy
Very easy to install. I got the product in two days. Love etrailer products. THANKS.
Always great experience.
Product does not help rear swag with fifth wheel camper but a half inch. On brand new truck as well. Not happy with product. Called to return them and want me to pay 27.00 shipping and stated in email that was sent to me I couldn’t return if installed. I’m not understanding this ? Do not buy ! I won’t be doing any more business with etrailer . Not helpful at all
Just installed on 2008 Hyundai Entorouge seems to work well. Only problem was that I had buy new hardware because the supplied hardware was standard not metric.
Works like expected. Keeps the truck looking level even under heavy loads.
I recently purchased a 2024 tundra hybrid platinum. With this being the luxury addition the rear suspension is lacking when in comes to towing when I would hook to my 7x16 enclosed trailer my truck really saved.
I purchased and installed the timbren ses stops and no more sag. The ride of my truck remains smooth when unloaded and the timbrens also stopef the side to side rocking. Will post another after I tow a few times.
Installed in about 15 minutes,very easy.I pick up my new truck camper next week so I do not know how it works yet,but looks like it will work like its suppose too
I received my order within days. It was exactly as I expected. The product works as advertised. I am a now a lifelong customer of etrailer.com.
Very easy to install, well made product but the instructions are minimal.
Yes about one year ago i installed this product with excellent results so far.
Simple installation and the cost is gre at.
Very efficient and great to work with. Will definitely use your company again. Thanks
Product arrived on time and does exactly what it describes. Little stiffer ride without a load but with a load it made my truck handle so much better at low and high speed.
Just as overtired , they stiffened up the ride , plus no more sag in rear ended of truck .
Just what my truck needed to stop the sag when I hook up to my 5th wheel.
Just received them just install them looks like they work great etrailer is always right on spot
Fast delivery and easy installation
Product arrived and installed as advertised. Great Shipping
Easy to install and does not affect the ride till you have a load, then they help support the load. Good product!
As always amazing customer service and products to match.
Very quick delivery, earlier than I expected. Easy to install. Just what was needed for rear weight support when pulling a trailer.
