Features to know about
Keep the Front End Level Under Heavy Weight: 14,000-lb Load Support
When you hang serious weight up front, like a plow or heavy equipment, the front end can sag and throw off steering and braking. The Timbren Front Suspension Enhancement System uses a pair of Aeon hollow rubber springs rated for 14,000 lbs to keep the front end level and stable. They mount directly above the axle to take on heavy loads, working with your factory suspension to keep traction, steering, and headlight aim right where they should be.
Smooth Out Rough Roads: Rubber Springs That Absorb Shock
Rough pavement and bumps can wear out a suspension fast. These hollow rubber springs soak up road shock and vibration before it reaches the cab. The progressive, convoluted design collapses smoothly under load to cushion impacts, improve roll stability, and prevent bottoming out. The result is a more comfortable and controlled ride when you’re loaded down or driving over rough ground.
Stay Steady in Crosswinds and Turns: Independent Spring Action
Each rubber spring works on its own to support either side of your front suspension. When you corner or hit an uneven surface, they respond independently to cut down on body roll and sway. Even with an off-center load or a plow extension hanging out front, the truck stays balanced and predictable through turns or crosswinds.
No Air Lines or Adjustments Needed: Simple Bolt-On Design
There’s no compressor, air hose, or gauge to mess with here. This kit replaces your factory bump stops and bolts straight to the frame using the included vehicle-specific brackets and hardware—no drilling required. Once installed, the springs automatically engage when needed and don’t require any maintenance or manual adjustment. It’s a straightforward setup that gives long-term support without extra equipment or tuning.

The timbren springs are working out better than expected. I installled new Monroe matic RV shocks front and rear on my 2006 Chevy Silverado 1500 just prior to putting the timbrens on the front and the sumo springs on the rear and the ride is great especially with a load or hauling my travel trailer and the ride is just as smooth empty. I highly recommend the timbren and sumo springs because they fit by application and there is nothing additional to buy. Thanks etrailer.
