Timbren Industries FRTT350E SES Suspension Enhancement System

The Timbren Industries FRTT350E SES (Suspension Enhancement System) is engineered to improve your truck's suspension performance when towing trailers or hauling heavy loads. This innovative system uses hollow rubber springs that activate progressively as weight increases, providing automatic load support without the need for air lines, compressors, or manual adjustments.

Key Features:

• Hollow rubber spring design eliminates metal-to-metal contact and harsh ride quality
• Progressive engagement provides support only when needed, maintaining factory ride when unloaded
• Maintenance-free operation with no air bags, compressors, or leak-prone components
• Reduces body roll, sway, and rear-end squat during towing and hauling
• Simple bolt-on installation typically completed in under an hour
• Increases load-leveling capability and overall suspension stability
• Durable Aeon hollow rubber construction resists weather, road salt, and UV damage
• Designed specifically for Ford F-350 trucks

The FRTT350E system installs between the frame and axle, acting as a supplemental spring that engages when your suspension compresses under load. This design preserves your vehicle's factory ride characteristics during everyday driving while providing critical support when you need it most. Ideal for contractors, RV towers, and anyone who regularly pushes their truck's payload capacity.
