      Description

      Progressive Suspension Enhancement. The Timbren Rear Axle SES Suspension Enhancement System improves stability and ride comfort for trucks carrying top-heavy loads such as truck campers. It works by progressively increasing spring resistance as load weight increases, reducing squat, sway, and roll for safer, more controlled handling on the road.

      Construction and Appearance. This system features patented Aeon hollow rubber springs paired with durable mounting brackets and spacers. The components are engineered to withstand severe service conditions, providing a strong, weather-resistant assembly that maintains performance over time without requiring maintenance.

      Installation. Installation is straightforward and typically takes under 30 minutes using standard tools. No drilling or special modifications to the vehicle’s frame are necessary, allowing for a simple, do-it-yourself setup in the driveway.

      Warranty. A lifetime warranty covers defects in materials and workmanship under normal use for the life of the vehicle on which the system is installed.

      Application. Specifically engineered to fit 1999 through 2004 F-250 Super Duty models, this severe service kit ensures maximum stability for hauling heavy, top-heavy loads without affecting the unloaded ride height.
