This ReadyLIFT 69-39400 4” SST Lift Kit for the 2019-2023 Chevy Silverado and GMC Sierra 1500 features exclusive components making the kit compatible with available Adaptive Ride Control Suspension (ARC)! The 69-39400 replaces the 69-3940 and works on trucks with or without ARC.  The new 69-39400 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 2019-2023 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. 69-39400 can easily allow for up to a 295/65-20 tire on a 2019-2022 Chevy as shown here with XD Series Demodog 20x9 0 offset wheels (35x11.50 max). This kit provides the right amount of lift without exceeding the CV limits working within the OEM tolerances.  (2019-2023 GMC Sierra 2023 Chevy can only fit up to a 295/55-20 tire due to fender flare wheel well restrictions.)

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, ReadyLIFT includes their 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.
