ReadyLift 4.0" SST Lift Kit for GM Full-Size 1500 4WD SUVs (2007–2014) — front 4" lift with factory-friendly install.

• Front lift achieved with rugged powder-coated steel strut extensions that bolt directly to the factory strut—no spindle or extensive modifications required.
• DOM tubular Upper Control Arm with OEM-style ball joints maintains alignment and steering geometry through the lift, reducing guesswork during installation.
• CNC-machined 6061-T6 billet aluminum differential drop brackets paired with a powder-coated steel skid plate protect the drivetrain and preserve driveline angles.
• Rear suspension is lifted with 3.0" powder-coated steel coil spring spacers to retain the factory ride, complemented by long, sturdy rear sway bar end links and bump stop extensions for balanced handling.
• Rear shocks remain in their factory mounting position thanks to steel shock extensions, preserving ride quality and compatibility with the stock setup.
• Tire and wheel compatibility: supports up to 33" tires on aftermarket wheels (commonly 33x12.50 max); minimal inner fenderwell trimming may be needed for 33x12.50, while certain wheel configurations (e.g., 22x9.5 with 5.5" backspacing or 17x9 +0 offset on 285/70R17) require no modifications; stock wheels may require spacers to avoid interference during full lock.
• Warranty and compatibility: Limited Lifetime Warranty plus ReadyGuard PowerTrain Warranty; not compatible with rear airbag suspension or AWD models; designed for aftermarket wheels and may require an adjustable rear track bar or drop bracket if axle shift occurs during installation.
