Built for Chevy and GMC heavy-duty truck owners who want more ground clearance without compromising driveline geometry, this 3.5-inch knuckle lift kit combines precision-engineered steel knuckles, forged upper control arms, and premium M1 monotube shocks to level your truck's stance while maintaining factory-like suspension geometry. The kit preserves your factory components — no cutting, drilling, or welding — and supports 33"–35" tires with proper wheel backspacing.
