Equip your 2021+ GM 1500 SUV with Belltech's 150222HK leveling kit and feel the superior handling you need. Our kit lifts the front of your vehicle 0" to +2.5" and 0" to +2" at the rear to set the perfect level ride height. Achieve a modern, uniform appearance while also improving handling and performance making quick maneuvers safe and precise. The front and rear suspension includes our robust Belltech lowering coilovers designed using high-quality, multi-functional components that are built to last. Each coilover includes a finely tuned Belltech damper that features a large, 2.4" (60mm) damper body and 35mm independent rebound and compression valves. Together, these details keep oil cool and deliver precise, consistent damping throughout travel. The external threads and spring perch offer customizable height adjustability. We feature a large main spring and smaller helper spring. Both the main spring and the helper spring are made of cold-formed tensile steel and are powder-coated to prevent rust and wear. The coilover uses a progressive rate polymer, open-cell, bump stop for ideal bump stop engagement, and the OE top mounts for simplified installation.
