The Fabtech 4-inch crossmember lift system for 2011–2019 GM 2500HD (2WD/4WD) delivers a robust suspension upgrade while retaining a clean factory stance. High-arched 1/4" thick lower control arm crossmembers and ductile iron steering knuckles preserve track width, and rear lift is via block and u-bolt. This variant includes Stealth shocks for controlled ride quality on lifted trucks.
