Product Overview
The ReadyLIFT 6" MAX 2.1 Suspension System is engineered specifically for 2020–2025 Chevrolet Silverado 2500HD/3500HD and GMC Sierra 2500HD/3500HD 4WD trucks seeking premium ride quality, improved suspension control, and oversized tire clearance while maintaining towing stability and factory drivability. This premium suspension package combines heavy-duty geometry correction with Falcon 2.1 monotube shocks for enhanced highway comfort and off-road capability.
At the core of the system are Falcon 2.1 monotube shocks designed to improve low-speed damping control, ride comfort, and suspension stability during towing, hauling, daily driving, and off-road use. The system includes heavy-duty fabricated steel crossmembers, fabricated upper control arms, differential drop brackets, forged torsion keys, OE-style cast steering knuckles, and a full-coverage differential skid plate engineered specifically for modern GM HD trucks.
ReadyLIFT engineered the MAX2.1 system to preserve OEM-style steering geometry and handling while providing a full 6 inches of lift and clearance for up to 37x12.50-inch tires on compatible wheel setups. Designed for both standard GM HD and AT4 applications, the system delivers improved capability and aggressive styling without sacrificing ride quality. Now Available at LEER!
