4" SST Lift Kit - GM Full-Size SUV W/ Forged UCA 2WD 1500 2007-2017

Raise your GM full-size SUV by 4.0 inches with the ReadyLIFT SST Lift Kit, featuring forged upper control arms and 4.0" steel strut extensions that attach directly to the factory strut without modifications.

Fits 2007-2018 GM full-size SUVs (6-lug 2WD), including Cadillac Escalade, Chevrolet Tahoe and Suburban, GMC Yukon, Yukon XL, and Denali. This kit is designed for aftermarket wheels, delivering a capable combination of height, control, and compatibility with modern wheel and tire options.

• Front lift: 4.0" achieved with powder-coated steel strut extensions that bolt to the factory strut with no spindle or major modifications.
• Upper control arm: 100% DOM tubular upper control arm with OEM-style ball joints pre-pressed into a strong crown, preserving OEM geometry.
• Bushings: TCT polyurethane bushings included for durable articulation.
• Rear lift: 3.0" powder-coated steel coil spring spacers to maintain the factory ride with a slight rake for towing or hauling.
• Rear suspension hardware: longer rear sway bar end links and bump stop extensions; steel rear shock extensions keep the factory rear shocks in place.
• Wheel / tire compatibility: supports up to 33" tires on aftermarket wheels; minor inner fenderwell trimming may be needed for 33x12.50 tires with aftermarket wheels.
• For stock wheels: a wheel spacer is required to prevent tire contact with the control arm during full locked turns; ReadyLIFT offers billet aluminum spacers (10-3485) for factory wheels with stud pockets next to the lug holes.
• Notes: installation may cause rear axle shift, necessitating an adjustable rear track bar or drop bracket, and rear auto ride modifications. Not compatible with rear airbag suspension.
• Warranty: backed by ReadyLIFT's Limited Lifetime Warranty.
