      Description

      Superior Suspension Upgrade. The Rough Country Suspension 4-Inch Suspension Lift Kit with M1 Monotube Shocks enhances your truck's ground clearance and handling for rugged off-road performance and aggressive street presence. Designed for 4WD models, it provides a durable solution to accommodate larger tires and improve ride quality while maintaining factory suspension geometry.

      Construction and Appearance. Precision-crafted components include lifted front knuckles, drop crossmembers, and rear lift blocks made from high-strength steel with corrosion-resistant finishes. The kit features zinc-plated M1 Monotube shocks that deliver consistent performance and resist harsh elements.

      Installation. Installation requires moderate mechanical skill with an estimated time of 8-10 hours and involves frame bracket and differential modifications. No drilling is necessary, although trimming factory-painted bumpers may be required for proper fitment.

      Application. Specifically engineered for 1999-2006 GMC Sierra 1500 4WD models, excluding 1999 Old Body Style (OBS) due to fitment constraints.
