Description

The Rough Country 4 Inch Suspension Lift Kit is engineered to enhance the stance and off-road capability of your 2019-2024 GMC Sierra 1500 4WD or 2019-2024 Chevy Silverado 1500 4WD. This comprehensive kit lifts and levels the vehicle, creating a commanding presence and offering ample clearance to accommodate up to 35x12.50 tires mounted on 10-inch wide wheels. The design prioritizes optimal suspension geometry while aiming to retain the factory ride quality, ensuring a balance between enhanced off-road performance and a smooth on-road experience. Construction includes robust front and rear crossmembers, a protective skid plate, and durable cast steel knuckles for longevity. Included in this kit are application-valved N3 series shock absorbers, designed to deliver balanced performance suitable for both on-road and off-road conditions. The fabrication process utilizes 100% precision laser-cut materials, ensuring accuracy and quality. Important fitment notes: This kit is specifically for Trailboss & AT4 models and requires cutting and drilling for installation. It does NOT fit GMC Denali models with Magnetic Ride Control, 2019 "Classic" models (2018 body style), or diesel engine models. Furthermore, it does NOT fit factory wheels; 20-inch or larger aftermarket wheels with 4.5-inch backspacing are required. It is recommended to test fit wheels before installation.
