    High-Performance Lift Kit. The Rough Country Suspension 6-Inch Suspension Lift Kit enhances your Silverado 1500 by raising the vehicle for increased ground clearance and an aggressive stance. It’s designed to improve off-road capability, allowing installation of 35-inch tires without additional modifications while maintaining ride quality and handling. This kit is ideal for enthusiasts seeking both aesthetics and a functional suspension upgrade.

    Construction and Appearance. Constructed with heavy-duty steel components including cast knuckles and reinforced crossmembers, the kit ensures durability on rugged terrain. Precision laser-cut materials and advanced CAD technology guarantee a perfect fit. Finished with durable coatings to resist corrosion, it maintains a professional look and long-term reliability.

    Installation. Installation requires a moderate skill level including minor cutting, drilling, and the use of a strut compressor. The full procedure typically takes 8-10 hours to complete.

    Warranty. This suspension lift kit is backed by a limited lifetime replacement warranty covering manufacturer defects for peace of mind.

    Application. Designed specifically for the 2025-2026 4WD V8 Silverado 1500 equipped with OEM Mon-Leaf Springs. It is not compatible with Trail Boss or ZR2 models due to their factory-installed 2-inch lifts and specialized dampers. This kit does not fit factory wheels and requires 20-inch or larger aftermarket wheels with 4.5-inch backspacing; some aftermarket wheels may require 0.25-inch spacers to fit properly.
