Timbren SES Rear Suspension Enhancement System for Select Ford F-250/F-350 1970-2004 (FRTT350E)

Fits select 1970-2004 Ford F-250 and F-350 trucks, including F-250 HD and Super Duty variants. This Timbren Suspension Enhancement System (SES) is engineered to eliminate vehicle squatting, sagging, and trailer sway by providing a progressive spring rate that adjusts to the load.

Instead of relying on complex air systems, the FRTT350E utilizes high-performance hollow rubber cushions that absorb road shocks and improve overall handling. This kit replaces the factory bump stops, providing additional support that remains out of the way when the vehicle is unloaded, maintaining your factory ride quality. Under load, the rubber springs compress to provide the stability and leveled stance needed for safe towing and hauling.

• Eliminates Sag and Sway: Automatically adjusts to uneven loads for a level, stable ride.

• Heavy-Duty Construction: Built from high-grade rubber to withstand harsh road conditions.
