The Timbren Suspension Enhancement System for 2011 International TerraStar rear suspensions adds rubber cushions that absorb shocks and automatically adjust to uneven loads to reduce sag while towing. The bolt-on kit installs without drilling or airlines and fits applications with more than 5 inches of clearance. Rated to support up to 11,000 lbs, it improves handling and stability for hauling and carries Timbren’s low-maintenance rubber‑spring design and lifetime warranty.
