Product Description

1. Advanced Functions
   Eliminate suspension sag, cushion road impacts, reduce swaying, and improve roll stability.
2. Compatible Vehicle Models
   This air - assisted spring kit is a direct OEM replacement for the GMRCK25D Timbren Rear Suspension Enhancement System. It is suitable for 2011 - 2023 Chevrolet Silverado / GMC Sierra 2500 HD and 3500 HD two - wheel - drive and four - wheel - drive pickup trucks.
3. Loading and Unloading
   There should be a clearance of 1/2" to 1 1/2" between the rubber spring and the axle to ensure the driving quality when the vehicle is unloaded.
4. Maximum Load
   The rated weight of this kit is 8000 pounds. It does not increase the vehicle's Gross Vehicle Weight Rating (GVWR). It provides progressive spring stiffness. When loaded, the suspension automatically adjusts to maintain vehicle balance. By reducing the friction between the leaves, it enhances the driving experience, contributes to steering control and braking efficiency. It softens the contact between the axle and the frame to reduce bottoming - out.

   No drilling or wiring is required. The SES kit can be installed within a few minutes using basic hand - held tools.
