Timbren SES (Suspension Enhancement System) for Sprinter 2500, 3500

The Timbren SES (Suspension Enhancement System) is a high-performance alternative to air bags, designed to eliminate rear-end sag, sway, and bottoming out. These systems feature Aeon® hollow rubber springs that replace the factory bump stops. Unlike air-filled systems, Timbren SES units are "progressive," meaning they stay soft when the vehicle is empty but become increasingly firm as you add more weight.

This "set-it-and-forget-it" solution is a favorite for trucks, vans, and SUVs used for heavy towing or hauling. Because they contain no air, they are immune to leaks and require zero maintenance or monitoring.

Features of the Timbren SES:

• Aeon® Hollow Rubber Springs: Engineered to deliver a progressive spring rate, providing more support as the load increases.
• Maintenance-Free Design: No air lines, no compressors, and no manual pressure checks; it cannot leak.
• Durable Construction: Built to withstand extreme temperatures and road salts, lasting the life of the vehicle.
• Easy Installation: Most kits are a direct bolt-on replacement for factory bump stops, requiring only basic hand tools and about 30–60 minutes.
• Lifetime Warranty: Backed by a lifetime warranty on the rubber springs and a "Satisfaction Guarantee."

Benefits of the Timbren SES:

• Eliminates Sag and Squat: Keeps the vehicle level while towing trailers or hauling heavy payloads, restoring proper steering and braking geometry.
• Reduces Body Roll and Sway: Dramatically increases stability, especially for top-heavy campers or during high-speed highway maneuvers.
• Prevents Bottoming Out: Protects the suspension and frame from harsh metal-on-metal contact when encountering large bumps or dips.
• Improves Ride Quality: The rubber springs act as a cushion, absorbing road shock and reducing the jarring sensation of heavy loads.
• Enhances Empty Ride: Designed with a small gap between the spring and the axle so it does not affect the ride when the vehicle is unloaded.
