Timbren Rear Spring Suspension Enhancement System Ram Promaster Vans

Eliminate rear-end sag, improve ride quality, and gain control—without complicated installs.
The Timbren SES (Suspension Enhancement System) is the ideal upgrade for any Ram Promaster carrying heavy gear, towing trailers, or built out for van life. Designed to replace your factory bump stops, the Timbren FPR001 kit installs easily using existing holes—no drilling or modifications required.

Built with Aeon® hollow rubber springs, this system cushions heavy loads, prevents bottoming out, and reduces body roll during cornering. Whether you’re navigating rough roads, driving cross-country, or simply adding extra weight with a conversion, Timbren delivers a safer, smoother ride.
