4in Suspension Lift Kit

The Rough Country 4in Suspension Lift Kit is specifically engineered for the 2019 4WD Chevrolet Silverado 1500 Trailboss and GMC Sierra 1500 AT4 models. This comprehensive kit lifts and levels your vehicle, offering a commanding stance and sufficient clearance to accommodate up to 35x12.50 tires mounted on 10-inch wide wheels with 4.5-inch backspacing. Rough Country has meticulously designed this kit to maintain optimal suspension geometry while preserving the factory ride quality, thereby enhancing off-road capabilities without compromising the truck's handling and smooth ride. This kit includes durable components such as front and rear crossmembers, a skid plate for increased chassis strength, and robust cast steel knuckles for exceptional durability and performance. The kit features a high-clearance crossmember design, fabricated lift blocks that are stronger than cast blocks, and application-valved N3 series shock absorbers for balanced on and off-road performance. Installation is estimated to take 8-10 hours and requires cutting and drilling. It is crucial to note specific fitment restrictions. This lift kit does NOT fit GMC Denali models equipped with Magnetic Ride Control. It is ONLY compatible with Chevy Trailboss models and GMC AT4 models; it does NOT fit standard models or other GMC trims. Furthermore, the kit does NOT fit factory wheels; 20-inch or larger aftermarket wheels are required, and they must feature 4.5 inches of backspacing. Always test fit wheels before installation.
