6 Inch Lift Kit | Mono Leaf Rear | N3 | Gmc Sierra 1500 2wd (2025-2026)

Built for GMC Sierra 1500 2WD owners who want a commanding stance and real tire clearance — this 6-inch suspension lift kit raises and levels your truck from front to rear while preserving factory suspension geometry. The combination of steel knuckles, drop crossmembers, and rear blocks keeps control arm angles close to factory specs, so your ride stays predictable even after lifting. You'll have enough clearance to run 35-inch tires without additional modifications.

Important notes
