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.

Provides additional support as needed, so you always have a nice, smooth, comfortable ride. And it'll allow the leaf spring ample movement while cushioning light loads, does not affect the empty ride of the vehicle. And these will become more rigid as more weight is added.
Does increase stability, provides great performance for hauling heavy loads and it will reduce vehicle sag. What's nice about these, they do work independently, side to side, so they will help compensate for any off center loads and they'll reduce body roll when you're swerving or turning corners. They'll even act as shock absorbers, taking the brunt of any bumps and rough roads, helps extend the life of your vehicle's suspension. Now it will include everything shown here. It does include the, let me just take these parts off.
These are the two Aeon Hollow Rubber Springs, the four vehicle specific mounted brackets, the two bottom ones, the two top ones. Here's your two top ones right here. And it does also include these four spacers that'll be installed with the hardware. Comes with the hardware for a nice, simple installation. These do replace the bump stops on the frame.
There's no drilling required. Capacity on the ski is 11,000 pounds and these Timbern Springs will not increase your vehicle's weight carrying capacity.

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.

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
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.

Seamlessly easy
Just what my truck needed to stop the sag when I hook up to my 5th wheel.
Sorry to report that the Timbren package arrived in original box that looked as though it had been ripped open and the carefully taped shut with clear packing tape. I thought at first that shipper had damaged it but all parts were there so I started install. Half way thru I discovered two of the lock nuts were stripped and threads on the right axle pad were burred at the start. We live 14 miles round trip from the closest ace hardware. I used a die to repair the axle pad threads but had to stop for the day to purchase new lock nuts. Feel like I got a used set for new price.
Very quick delivery, earlier than I expected. Easy to install. Just what was needed for rear weight support when pulling a trailer.
Easy to install and does not affect the ride till you have a load, then they help support the load. Good product!
Great Product, arrived quickly and packaged well.
Will be buying from them in the future.
Product arrived sooner than expected, yea!!! All components were easily installed thanks to your videos. A test drive today revealed that all is in good working order. Thanks so much for the prompt delivery and very descriptive videos.
