Timbren Industries FRETRAHD SES Rear Suspension Enhancement System 8600 lb Capacity

The Timbren Industries FRETRAHD SES (Suspension Enhancement System) is a heavy-duty rear suspension upgrade designed to eliminate sag, sway, and roll when towing and hauling. Featuring patented Aeon hollow rubber spring technology, this system provides progressive load support with an 8,600 lb capacity, automatically adjusting to changing loads without requiring any maintenance or adjustments.

Key Features:

• 8,600 lb load capacity for heavy-duty towing and hauling applications
• Patented Aeon hollow rubber springs provide progressive spring rates that increase resistance as load increases
• Zero maintenance design—no air lines, fittings, compressors, or leak concerns unlike air bag systems
• Maintains factory ride height when unloaded, engaging only when weight is applied
• Simple bolt-on installation using included powder-coated steel mounting brackets—typically installs in under 30 minutes with basic hand tools
• Self-damping rubber springs act like shock absorbers, providing superior ride quality loaded or unloaded
• Cannot be punctured—hollow open-cell design eliminates air bag vulnerabilities
• Backed by Timbren's lifetime warranty against defects in materials and workmanship

Unlike add-a-leaf springs that negatively affect unloaded ride quality, the FRETRAHD SES system only engages when weight compresses the suspension, ensuring your vehicle rides comfortably whether loaded or empty. The progressive spring rate technology provides increased stability and control, reducing dangerous suspension bottoming out on rough roads. Built from natural rubber and precision-engineered steel components, this system delivers reliable performance in extreme temperatures from sub-freezing winters to desert heat.

Note: This suspension enhancement system does not increase your vehicle's GVWR (Gross Vehicle Weight Rating). Always ensure loads do not exceed manufacturer specifications.
