      Description

      Advanced Suspension Upgrade. The ReadyLIFT 5 to 6-Inch MAX2.1 Suspension Lift Kit with Falcon 2.1 Monotube Shocks enhances ride quality, off-road capability, and vehicle stance. Designed for versatile use, it delivers improved comfort and handling for daily driving, towing, and rugged terrain. This kit is essential for fitting larger wheels and tires without compromising performance or safety.

      Construction and Appearance. Crafted from heavy-duty fabricated steel with laser-cut and CNC-formed components, the kit features 3/16" and 1/4" steel plates for durability. It includes induction hardened chrome-plated shock shafts engineered to resist damage and corrosion, complemented by robust cast iron knuckles and forged torsion keys. The finish ensures a long-lasting, corrosion-resistant assembly capable of withstanding off-road conditions.

      Installation. Installation is moderately complex and estimated at about 12 hours, not including alignment and wheel/tire assembly. No vehicle drilling is indicated, but professional tools and expertise are recommended to ensure proper vehicle function and safety.

      Application. Specifically designed to fit the 2011 through 2019 Sierra 2500 HD, with the note that the single cab configuration has not been validated for fitment or drivability. Some trucks equipped with a tow package may require custom-length U-bolts sourced locally for proper installation.
