ReadyLIFT 4.0" SST Lift Kit- GM 1500 2025-2026

ReadyLIFT is excited to announce our all-new 4" SST Lift Kit for the 2025-2026 Chevy Silverado and GMC Sierra 1500 with exclusive components making the kit compatible with available Adaptive Ride Control Suspension (ARC)! The new SST Lift Kit provides a great lift solution to achieve an aggressive yet daily drivable lifted stance while still maintaining the important factory ride and handling.

ReadyLIFT offers a no-cut 4.0" SST lift kit for the 2025-2026 GM 1500 trucks! This new SST lift kit provides 4" of front lift and includes a 3" rear lift block. Front lift is achieved with heavy-duty laser-cut fabricated steel top mount strut extension with an offset design to correct the strut and wiper seal angles. A CNC-machined billet Aluminum pre-load spacer is also included. Combined this configuration provides 4 inches of front lift with minor design variations to improve driveline orientation over the previous 69-3940. This kit provides the right amount of lift without exceeding the CV limits working within the OEM tolerances.

This all-new, no-cut kit includes new tubular steel upper control arms with optimized ball joint pivot angles and maintenance-free TCT pivot bushings. The new upper control arms are an essential component of our new 4" SST Lift Kit to ensure proper suspension geometry.

For the rear, we include our popular time-tested 3" tall OE-style cast iron rear lift blocks with built-in axle pad locating ears and new longer U-bolts. With the 3" rear blocks, this new GM 1500 truck will have a very subtle rake that looks great with the all-new GM body lines even while towing or hauling payload.
