Show original supplier description
The SuspensionMAXX HD Stage 2 Leveling Kit (SMX-20252) offers a comprehensive solution for leveling GM HD trucks, providing up to 3 inches of front lift while maintaining optimal suspension geometry and travel. Included in the kit are CNC-machined aluminum differential and skid plate spacers with hardened 10.9-grade fasteners to ensure proper driveline angles. The kit also features Bilstein 5100 front and rear shocks, along with shock extensions that are required for the 5100 shocks to prevent overextension. Longer shock studs are provided to secure the factory wire harness. This leveling kit supports all-terrain tire sizes up to 35 inches, and the included hardware ensures a complete installation. This kit is specifically designed for 2020-2026 Chevrolet Silverado and GMC Sierra 2500HD/3500HD trucks. It is noted that the included shock extensions must be used when installing the Bilstein 5100 Series shocks. For optimal tire fitment, it is recommended to use the factory or a 9.0-inch wheel.
