Features to know about
Stay Level and Confident Under Heavy Loads: 8,600-lb Rear Support
Heavy trailers, campers, or bed cargo can make the rear sag and the front rise, throwing off handling and braking. The Timbren Rear Suspension Enhancement System adds up to 8,600 lbs of rear support to keep your vehicle level and stable when hauling or towing. Each hollow rubber spring mounts above the axle to share the load with your factory suspension, improving traction and steering control when the weight is on.
Smooth Out Rough Roads: Progressive, Shock-Absorbing Rubber Springs
Empty or loaded, road shock can make every bump feel harsh. These Aeon hollow rubber springs flex easily over light bumps but get progressively stiffer as more weight is added. The barrel-stack design cushions the ride on rough roads and helps prevent bottoming out, taking strain off your leaf springs and extending suspension life.
Stay Steady in Crosswinds and Turns: Independent Side-to-Side Action
When you haul an off-center load or turn sharply, body roll can make the vehicle feel unsteady. Each Timbren spring works on its own side of the axle to counter sway and roll, keeping you more stable through corners and crosswinds. The improved balance also helps reduce trailer sway so everything behind you tracks straighter.
Install It Once and Get to Work: Bolt-On Design with No Air Lines
You don’t need compressors, hoses, or gauges to get reliable load support. This system bolts in place using vehicle-specific brackets and replaces your factory bump stops—no drilling required. Once installed, it automatically adjusts with load weight for a level ride every time without any maintenance or air pressure checks.

After one year still working like day one. Probably one of the best modifications I’ve ever done to this truck. Won’t have a hauling truck without them going forward.
