ReadyLift 2.25"F / 1.5"R SST Lift Kit

 

The ReadyLIFT 2.25"F / 1.5"R SST Lift Kit is engineered for GM truck and SUV owners seeking improved ride height, larger tire clearance, and enhanced off-road capability while maintaining factory ride comfort and suspension geometry. Available for applications including 2007–2020 GM 1500 SUVs and 2002–2012 Chevrolet Colorado, GMC Canyon, and Hummer H3 models, this Smart Suspension Technology system delivers a balanced suspension upgrade ideal for daily driving, towing, and weekend trail use.

Built around ReadyLIFT’s SST suspension architecture, the GM SUV system features the company’s popular front spacer design paired with CNC-machined 6061-T6 billet aluminum rear coil spring spacers that provide lift without compromising suspension travel or ride quality. The Colorado/Canyon/H3 systems are engineered with application-specific suspension correction components designed to maintain proper steering geometry and driveline alignment after lifting.

The SST systems provide approximately 2.25–2.5 inches of front lift and 1.5 inches of rear lift, creating a mild lifted stance while retaining slight factory rake for towing and hauling capability. ReadyLIFT engineered these systems specifically to preserve OEM ride characteristics while allowing fitment of larger wheel and tire combinations. The GM SUV platform supports up to 33-inch tires depending on wheel width, wheel offset, and tire design.

Additional features include heavy-duty billet construction, application-specific mounting hardware, and geometry-correct suspension spacers designed for long-term reliability. The GM SUV systems are specifically engineered for 2WD and 4WD vehicles while retaining stable highway handling and comfortable ride quality. ReadyLIFT notes these systems are completely bolt-on and require no permanent modifications during installation.

Engineered with vehicle-specific fitment, the ReadyLIFT 2.25"F / 1.5"R SST Lift Kit delivers improved stance, enhanced suspension capability, and larger tire clearance while maintaining factory-like comfort and drivability.

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 ground clearance, towing stability, overlanding, or a more aggressive truck or SUV stance, the ReadyLIFT 2.25"F / 1.5"R SST Lift Kit delivers reliable suspension enhancement. Now Available at LEER!
