Built for Silverado and Sierra 2500HD/3500HD owners who want real ground clearance without factory rake — this 3.5-inch knuckle lift kit delivers leveled stance, driveline geometry correction, and the clearance to run 33–35 inch tires. Precision-engineered knuckles and forged upper control arms preserve your truck's suspension geometry while reducing CV bind.
