Timbren Industries FERSDLB SES Suspension Enhancement System Helper Springs

The Timbren Industries FERSDLB SES (Suspension Enhancement System) provides a progressive suspension upgrade for Ford E-Series vans. This hollow rubber spring system replaces factory bump stops to deliver superior load support and ride quality when towing or hauling heavy loads.

Key Features:

• Aeon hollow rubber spring technology provides progressive rate support that engages smoothly under load
• Eliminates squat, sway, and body roll when carrying cargo or towing trailers
• No air lines, compressors, or maintenance required—100% mechanical operation
• Installs in approximately one hour with basic hand tools, no drilling required
• Works with existing suspension system to increase load capacity and improve stability
• Durable rubber construction withstands harsh weather and road conditions
• Maintains factory ride quality when unloaded, activates progressively as weight increases

The SES system is ideal for contractors, fleet operators, and recreational users who need consistent performance whether driving empty or fully loaded. Timbren's hollow rubber spring design compresses progressively, providing just the right amount of support based on actual load weight.
