Timbren Industries JFTJ SES Suspension Enhancement System

The Timbren Industries JFTJ SES (Suspension Enhancement System) is a progressive suspension upgrade designed to improve ride quality, stability, and load-carrying capacity for trucks and commercial vehicles. This innovative system uses hollow rubber springs made from Aeon® hollow rubber technology that activates progressively under load, providing support exactly when and where you need it.

Key Features:

• Hollow rubber spring design provides progressive load support without air bags or hydraulics
• Eliminates squat when towing trailers or hauling heavy cargo
• Reduces body roll and sway for improved handling and safety
• Maintenance-free operation with no air lines, compressors, or leaks to worry about
• Easy bolt-on installation with no drilling required
• Works independently of existing suspension for seamless integration
• Lifetime warranty against defects in materials and workmanship

Unlike air bag systems that require constant monitoring and maintenance, the Timbren SES system is completely self-contained and activates automatically when weight is applied. The hollow rubber springs compress gradually, becoming firmer as load increases, providing optimal support throughout the entire weight range. When unloaded, the vehicle returns to its normal factory ride quality. Ideal for contractors, RV owners, and anyone who regularly tows or hauls heavy loads.
