ReadyLift 2.5"F / 1"R SST Lift Kit

 

The ReadyLIFT 2.5"F / 1"R SST Lift Kit is engineered specifically for 2000–2006 GM SUV and SUT 1500 platforms seeking improved ride height, larger tire clearance, and enhanced appearance while maintaining factory ride comfort and drivability. Designed around ReadyLIFT Smart Suspension Technology, this suspension system provides a balanced mild lift ideal for daily driving, towing, hauling, and light off-road use.

Built around ReadyLIFT’s proven SST suspension engineering, the system includes forged front torsion keys indexed specifically for GM SUV and SUT applications. These heavy-duty forged keys provide approximately 2.5 inches of front lift without excessively over-cranking the factory torsion bars, helping maintain predictable ride quality and suspension geometry.

The rear suspension is lifted using 1-inch CNC-machined billet aluminum rear coil spacers engineered specifically for six-lug GM SUV and SUT models. The system maintains a slight factory rake that improves towing and hauling stability while delivering a more aggressive leveled stance. ReadyLIFT also includes front shock extensions designed to preserve proper shock travel and suspension performance after installation.

The SST lift system is compatible with both 2WD and 4WD applications including Chevrolet Tahoe, Suburban, Avalanche, GMC Yukon, Yukon XL, Denali, and Cadillac Escalade models. ReadyLIFT confirms the system supports up to 33x11.50 tires on 9-inch-wide wheels with +12 offset for no-rub fitment on most applications.

Engineered specifically for GM full-size SUV and SUT platforms, the ReadyLIFT 2.5"F / 1"R SST Lift Kit delivers improved ground clearance, larger tire capability, and enhanced vehicle stance while preserving OEM-style ride comfort and handling characteristics.

Installation is designed as a complete bolt-on suspension system using application-specific hardware and detailed installation instructions. ReadyLIFT recommends professional installation and alignment after installation.

Whether you're upgrading for larger tires, improved towing stance, off-road capability, or a more aggressive SUV appearance, the ReadyLIFT 2.5"F / 1"R SST Lift Kit delivers reliable suspension enhancement for GM SUV and SUT applications. Now Available at LEER!
