4" 2025 GMC Sierra 1500 SST Lift Kit by ReadyLift

This ReadyLIFT 4” SST Lift Kit for the 2025+ Chevy Silverado 1500 is a great update that is compatible with Adaptive Ride Control Suspension (ARC). This innovative kit delivers an aggressive, daily-drivable stance while preserving factory ride quality and handling characteristics. With 4" front lift and 3" rear lift, this system ensures a leveled look with a slight functional rake—perfect for towing or hauling.

Front lift is achieved using heavy-duty, laser-cut fabricated steel strut extensions combined with a CNC-machined billet aluminum preload spacer. This design optimizes driveline orientation and maintains proper CV angles within OEM tolerances. The kit also features upgraded tubular steel upper control arms with optimized ball joint angles and ReadyLIFT’s maintenance-free TCT pivot bushings for improved suspension geometry and durability. At the rear, the system includes 3" OE-style cast iron lift blocks with axle pad locating ears and extended U-bolts to ensure secure fitment. The result is a sleek, functional stance that complements the bold body lines of the GM trucks—whether you're cruising the highway or hauling heavy loads.

This 4” SST Lift Kit is 100% bolt-on and requires no frame cutting or welding, making it one of the most installer-friendly kits on the market. It's the ultimate lift solution for GM 1500 owners who want style, strength, and performance—without compromising drivability.
