ReadyLIFT is excited to announce our all-new 4” SST Lift Kit for the 2025 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.; Note: Not compatible with 2019 Limited OLD Body Style.; Note: NOT intended for off-road use or abuse.; ReadyLIFT offers a no-cut 4.0" SST lift kit for the 2025 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.; Note: This kit is not compatible with Trail Boss ZR2 AT4 or AT4X.; Note: Vehicles with Mono-leaf rear springs require 67-39530UB.
