Timbren Industries FFF53B SES Suspension Enhancement System

The Timbren Industries FFF53B SES (Suspension Enhancement System) provides a reliable suspension upgrade designed to improve your vehicle's load-carrying capability and towing performance. This system uses hollow rubber springs made from Aeon® rubber that act as progressive rate bump stops, engaging when you add weight or encounter rough terrain.

Key Features:

• No-maintenance hollow rubber spring design requires no air lines, compressors, or adjustments
• Progressive spring rate increases support as load increases
• Reduces body roll, sway, and rear-end squat when towing or hauling
• Helps maintain proper headlight aim and improves steering control under load
• Installs in place of factory bump stops with basic hand tools
• Durable Aeon® rubber construction resists weathering, oils, and road chemicals
• Lifetime warranty from Timbren Industries

The FFF53B SES system installs between the frame and axle, providing additional support exactly when you need it. When your vehicle is empty, the Timbren springs remain dormant. As you add cargo weight or attach a trailer, the suspension compresses and engages the SES springs, providing progressive support that increases with load. This simple, mechanical system eliminates the complexity of air bags while delivering consistent performance in all weather conditions.
