When you’re towing or hauling, sag in the rear end can throw off steering and braking. The Timbren Rear Suspension Enhancement System adds up to 6,000 lbs of extra support above the axle to keep your vehicle level and stable under load. Each hollow rubber spring stiffens progressively as weight increases, so the truck stays steady whether you’re hauling gear in the bed or pulling a trailer down the highway.
Bumpy roads and uneven pavement don’t have to beat up your suspension. These Aeon hollow rubber springs act like extra shock absorbers, taking the hit from potholes and rough surfaces before it reaches the frame. They cushion light loads while allowing normal leaf spring movement, keeping the ride comfortable when empty and steady when loaded.
When curves or crosswinds push your setup around, each Timbren spring works independently to support its side of the vehicle. That independent action helps cut down on sway and body roll when turning corners or hauling off-center loads. With better roll stability, your vehicle feels planted and trailers track straighter behind you.
No air lines, compressors, or gauges—just a straightforward install that replaces your factory bump stops. The custom brackets bolt directly to the frame above the axle with no drilling required. Once installed, there’s no air pressure to monitor or parts to adjust—just reliable support that works automatically every time you load up.

Excursion factory springs seem underrated. Timbren’s recommended spacing still allows to much rear end squat. I added more spacers for No gap. Actually helped with body roll when unloaded. This spacing was discussed with Timbren representative beforehand. Timbren has lifetime warranty

There should be a sizeable gap between the Timbren springs and the vehicle axle. The Timbren kit should only engage the axle when the vehicle is bearing a hefty load. This is to prevent un-loaded ride quality from being altered, but provide extra support when a heavy load is in the mix.
