Timbren Industries FRETRA Rear Suspension Enhancement System for Ford E-Transit

The Timbren Industries FRETRA SES Suspension Enhancement System is a rear suspension upgrade specifically engineered for 2022-present Ford E-Transit vans and motorhomes. This maintenance-free system eliminates rear sag, sway, and roll when towing or hauling heavy loads, providing a safer and more controlled driving experience.

Key Features:

• Features patented Aeon® hollow rubber springs with progressive spring rate technology
• 5,600 lbs. load capacity per pair
• Installs in under 30 minutes with basic hand tools - no drilling, no air lines required
• Automatically engages under load while maintaining factory ride quality when unloaded
• Maintenance-free design with no airlines, fittings, or leaks to monitor
• Eliminates vehicle squatting, rear sag, and trailer sway
• Improves handling stability and reduces crosswind drift
• Absorbs road shocks and cushions bumps for improved ride quality
• Backed by lifetime warranty

What's Included:

• (2) Mounting plates
• (2) Patented Aeon® hollow rubber springs
• All necessary installation hardware

The progressive spring rate design means the Aeon® rubber springs push back harder as load increases, automatically adjusting to varying weight conditions. After installation, a ½" to 1½" gap between the rubber spring and vehicle axle ensures comfortable unloaded ride quality. Unlike air bag systems, Timbren SES kits require zero post-installation maintenance and work in conjunction with your existing suspension to protect against overloading, bottoming out, and suspension damage.
