ReadyLift 4" SST Lift Kit for GM Full-Size SUVs (2015–2020, 2WD/4WD)

Elevate your 2015–2020 GM 1500-series SUV with a true bolt-on 4.0" lift that preserves factory integrity and requires no drilling, cutting, or welding. This kit adds ground clearance, opens up space for larger tires, and is designed to work with aftermarket wheels for a confident, capable ride both on and off the road.

• Front suspension upgrades: durable powder-coated steel strut extensions paired with a 100% DOM tubular upper control arm, OEM-style ball joints, and TCT polyurethane bushings for smooth operation and long life.
• High-strength geometry: patent-pending CNC-machined 6061-T6 billet aluminum differential drop brackets maintain front axle and CV angles, reducing installation time and preventing driveline issues.
• Rear suspension preservation: 3.0" powder-coated steel coil spring spacers, with longer rear sway bar end links, bump stop extensions, and steel rear shock extensions to maintain a near-stock ride quality.
• Protection and durability: a powder-coated plate steel skid plate guards the differential, continuing factory-level protection with enhanced off-road capability.
• Wheel and tire compatibility: supports up to 33" tires on aftermarket wheels (commonly 33x12.50); compatible with 22x9.5 (5.5" backspacing) and 17x9 (+0 offset) on 285/70R17 (no rubbing, minor trimming for 295/70R17).
• Fit, warranty, and notes: designed for aftermarket wheels, not AWD vehicles. If using stock wheels/tires, a wheel spacer is required to prevent contact at full lock. Installation may shift the rear axle, potentially needing an adjustable rear track bar or drop bracket. Not compatible with rear airbag suspension. Backed by a Limited Lifetime Warranty and ReadyGuard PowerTrain Warranty.
