Timbren Industries FR250SDJ-P4 SES Suspension Enhancement System Kit 2017-2019 Ford F-250 Super Duty 4WD

The Timbren Industries FR250SDJ-P4 Suspension Enhancement System (SES) is engineered specifically for 2017-2019 Ford F-250 Super Duty 4WD trucks to provide progressive load support and eliminate suspension sag. This hollow rubber spring system mounts directly to your existing suspension using the factory jounce bumper mounting locations, requiring no drilling or modifications.

Key Features:

• Aeon hollow rubber spring technology provides progressive rate support that engages automatically under load
• Eliminates suspension sag when hauling heavy cargo or towing trailers
• No air lines, compressors, or maintenance required—completely self-contained system
• Quick installation using OEM jounce bumper mounting points
• Improves vehicle stability, reduces body roll, and enhances braking performance under load
• Does not affect unloaded ride quality—activates only when needed
• Backed by Timbren's lifetime warranty

The SES kit provides up to 6,000 lbs of additional load support capacity, making it ideal for work trucks, RVs with heavy equipment, and vehicles frequently used for towing. Unlike air bags or hydraulic systems, Timbren's rubber spring technology is maintenance-free and won't leak or fail over time. Installation typically takes 30 minutes or less with basic hand tools.
