Features to know about

Keep Your Truck Level When Towing: 11,000-lb Rear Suspension Support

An example of sag on a vehicle's rear axle under a heavy load

Nothing throws off your ride like a sagging truck when you hitch up a loaded trailer. These 11,000-lb capacity rear suspension springs provide strong support, keeping your truck level and improving handling so you can tow with confidence.

No More Squat When Loading Up: Strong Load Support for Your Truck Bed

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.

Stay in Control on the Road: Improved Towing Stability

An example of a trailers swaying

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.

Smooth Out Rough Roads: Absorbs Bumps and Shocks

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.

Better Handling Around Turns: Independent Suspension Action

Timbren suspension system works to prevent body roll

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.

No Airbags to Maintain: Simple, Maintenance-Free Support

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.

Video Transcript for Review of Timbren Vehicle Suspension - Rear Axle Suspension Enhancement System - T35AV

Hi, everybody, Andy here with etrailer.com. Let's take a real quick look together at this Timbren Rear Axle Suspension Enhancement System. Now this system has been designed to fit your 2007 to 2009 Dodge Sprinter 3500. Then your 2007 to 2015 Freightliner Sprinter 3500, then your 2010 to 2015 Mercedes-Benz Sprinter 3500. Then your 2016 to 2021 Freightliner Sprinter 3500, both the two and four-wheel drive, and then finally, the 2016 and newer Mercedes-Benz Sprinter, the 3500, both again, two and four-wheel drive. Now, on custom-fit parts such as this suspension system, I would recommend taking advantage of our Vehicle Fit Guide here at etrailer.com.

Simply input the year, make and model of your vehicle and our Fit Guide will confirm if this kit will work for you or if we have something comparable that will work for you. Now, these hollow rubber springs have a capacity of 11,000 pounds, and they're gonna mount to existing attachment points on your Sprinter to give you strong rear axle support to reduce sag and improve handling. These springs are also going to provide additional support as needed, so you always have a smooth, comfortable ride, allowing the leaf spring ample movement while cushioning loads, and these are going to ride just as smoothly when you're not hauling a load. They become more rigid the more weight that is added for greater performance when you're hauling a heavier load, so that's gonna increase the stability and reduce the vehicle sag on your Sprinter. Now, these are also going to work independently, adjusting side to side, helping to compensate for off-center loads, and it's also going to help reduce body roll when swerving or turning corners, and these springs also act as shock absorbers, taking the brunt of bumps and rough roads, extending the life of your Sprinter's suspension.

So, I do kinda have them loosely assembled here as to how they're going to mount underneath your Sprinter. As you can see, these springs are hollow, so you are going to get these two hollow rubber springs, and then the vehicle-specific brackets that you see here, and then the hardware for a pretty simple, straightforward installation, and instructions are included to guide you through that installation process. No drilling's gonna be required, which is nice. And again, the capacity is 11,000 pounds, but I do wanna point out that these Timbren springs do not actually increase your Sprinter's weight-carrying capacity, so you do wanna make sure that you're not exceeding your manufacturer's recommended weight limit. And if you do decide to pick these up, we would love to hear back from you regarding the installation and how these are working out for you, so 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 share some photos with us as well in regards to the installation process and what the finished product looks like underneath your Sprinter.

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.

I have not fully loaded my Odyssey yet BUT compare to original “pacifiers” which are made from kinda tough popcorn, those timbers are looking reliable.



by:

Easy installation. Good quality.



by:

Easy to install. Works as advertised. Etrailer rocks!



by:

Installed this on my 2001 Explorer. Install is easy (assemble unit, bolt on in place of existing bump stop). Annoyed to find it doesn't fit. Specs are gap 1/2"-1-1/2"; there was a gap of 2-3/4". Yeah, they sell spacers for $27 each, but it's really annoying to buy a $225 product that says it fits your truck, only to find that you have to spend 50% more to actually adapt it to your truck!



by:

Very easy to install. I got the product in two days. Love etrailer products. THANKS.



by:

Very easy to install took about 30 minutes. If it manages the weight of my trailer I will be more impressed with your product.



by:

Install was a breeze, can't wait to tow our camper with these babies on the Tundra



by:

Fast shipping would definitely recommend



by:

Quick delivery and exactly as described!



by:

Very easy installation!



by:

Very poor packaging. The box is coming apart and USPS reinforced it. Found out this product doesn,t work on a 2018 Winnebago Intent. It will cost me almost $[XX] to return it.



by:

Shipping was fast, product looks to be well made.



by:

Customer service was great. Fast delivery. Very easy to install. 35 minutes it was done.



by:

Easy installation and perfect fit!



by:

Perfect fit for my 2024 Toyota Tundra rear suspension. I tow a trailer every weekend and after installing this rear suspension suppport upgrade, no more squat or swag on truck bed



by:

easy to install, Solved my trailer bouncing over bumps problem.



by:

Very quick delivery, earlier than I expected. Easy to install. Just what was needed for rear weight support when pulling a trailer.



by:

Great job. Will use etrailer again.



by:

Great product there leveled the load and made tow way better.

Thanks



by:

Got them a day ago and installed the next day. Super easy installation.



by:

What a great product. This has made a night and day difference pulling a 5th wheel.



by:

Really not sure it's doing anything. No noticeable difference when towing my camper.



by:

Part was reasonably priced and arrived early. Very happy with the process.



by:

Service is great and product appears to function as advertised. For what it is seems like product is priced a little high. I'd be very surprised if it costs more than $20 to make them.



by:

I bought a set for my F250 and like them so much that I bought a set for my F350. It prevents the vehicle from sagging in the rear when hauling towing heavy objects. Makes for a smoother and more stable riding experience.
