Fabtech’s 4-inch crossmember lift kit for 2011–2019 GM 3500HD (2WD/4WD) is a performance-oriented system that balances durability with factory-like fitment. It uses 1/4" thick high-arched crossmembers, ductile iron steering knuckles to keep the track width near stock, and a front differential skid plate. Rear lift is handled by block and u-bolt hardware, and this version includes Stealth shocks for refined damping.
