2011-2019 GM HD 3" SST 2.1 Lift Kit w/ FCA & Falcon 2.1 Shocks (62-35160)

The ReadyLIFT 3-inch SST2.1 Lift Kit for 2011-2019 GM 2500HD/3500HD trucks is a comprehensive suspension upgrade that goes beyond a simple leveling kit. By including heavy-duty fabricated upper control arms, this system corrects ball joint angles and increases suspension travel. The kit utilizes forged torsion keys to provide 3 inches of front lift, while the Falcon 2.1 performance shocks offer a significant improvement in damping over the factory units, making it an ideal choice for owners who want to run 35-inch tires without sacrificing highway comfort or towing stability.

Features

• Heavy-duty fabricated steel upper control arms improve strength and provide proper ball joint pivot angles.
• Falcon 2.1 Monotube performance shocks are specifically valved for GM HD trucks to provide superior damping.
• Forged torsion keys provide a reliable and adjustable front lift while maintaining factory ride quality.
• Torsion bar unloading tool-compatible design ensures a safe and straightforward installation.
• Includes differential drop spacers to maintain proper CV axle angles and reduce wear.
• Fabricated 1-inch rear lift blocks provide a subtle lift to maintain a slightly raked or level stance.
• Includes heavy-duty iron-casted torsion key adjusters for maximum durability under load.

Notes

• A torsion bar unloading tool is required for a safe installation of the new torsion keys.
• Vehicle alignment is mandatory after installation to ensure proper tire wear and handling.
