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.
Install was easy. Raised our Thor Gemini up as product said it would. Great job etrailer!
They definitely reduced sway and lean when driving. But also seems like you really feel every bump and increase road noise?
I assume since vibration from axle can now travel directly to frame?
Might need to upgrade shocks?
Might soften liitle over time?
Might need to get softer onesv
Only have gone 80 miles with them so far.
Will give it another few hundred miles and see what feel then.
Overall pretty happy So far.
2017 Thor Gemini TX
had this product before. left it on my old truck when I traded. Now I have to replace it, really like what it does for my towing a travel trailer. just have to find time to put it on. speedy delivery arrived undamaged, which is nice.
Works great on my 2016 town and country for hauling my pop up camper.
Strainer/basket is holding up well after one year of use in our RV, no issues.
Fast delivery. Disappointed with the instructions. Sense the item was ordered vehicle specific. The instructions said tighten bolts to manufactures specifications.
Works great on my Honda odessey !! Great customer service as always!
Very fast shipping, had product in 2 days! Very easy to install. Hardest part was lifting the RV.
The product first arrived in a damaged box with one of the washers missing, but ETrailer did resupply that. The hardest part was finding a shop able (needs the right tools to depress coil springs) and willing (a potential liability issue messing with suspension) to replace it for a reasonable cost. Eventually a local tire shop agreed to. This was for a 2014 Honda Odyssey, especially for pulling a pop-up. Took two camping trips last summer, one before and one after installation, and I have been pleased with the added stiffness in the rear suspension. It made about 1 to 1.5 inch of difference in resting position when fully loaded and towing and has helped smooth out bumps and humps in the road - both when towing and not.
Have not driven yet, just installed. Added Monroe coil-overs as well, thanks etrailer.
Customer service is exceptional and any questions were answered immediately
Delivery was fast, instal was quick & easy. Later today I will see how they work when I hook up to the 5th wheel. By all indications right now I believe they exceed my expectations.
Good product, I’ve attached a couple photos. The last one is a before and after
I put this product on my Trooper. The install was easy is you take the back wheels off. I towed this weekend and I did not bottom out. If they hold up over time, this is a great product.
I would recommend this product to anyone. I pull trailers with a 1/2 ton truck and will never have another one without this product on it.
Price was good compared to other sites. Shipped very fast. Installation was very easy.
Put them on and it is exactly what I need to keep truck level when hauling fifth wheel. Easy to install too
Excellent quality, good prices and great shipping ! Thanks
Fit and functions as described. Installation was simple on my '05 Silverado.
Did my due diligence researching this product, including other customer reviews.
Can't wait to install them, but the Winnebago has been put to sleep for the season. I'll submit a performance report in the spring.
BIG difference in handling a load or trailer ... what a great product!!!
Great fitment
15 mins to install and what a difference…. Went from a few inches of sag in the rear to only an inch and over 1000lbs tongue weight didn’t know the trailer was attached to the truck
This product was delivered quickly and efficiently. The quality of the product is excellent and look forward to seeing how they work when we are towing our trailer.
Very easy to install
