Chevrolet Silverado & GMC Sierra 1500 2019-2025 4'' Front with 3.0'' Rear SST Lift Kit - Cast Steel Upper Control Arms Readylift

ReadyLIFT is excited to announce our all-new 69-39400 4” SST Lift Kit for the 2019-2024 Chevy Silverado and GMC Sierra 1500 with exclusive components making the kit compatible with available Adaptive Ride Control Suspension (ARC)! The new 69-39400 will replace 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 2019-2024 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. (2019-2024 GMC Sierra 2023-2024 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, 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. Before ordering a ReadyLIFT GM1500 Lift Kit, please check the rear leaf spring for kit compatibility. The mono-leaf is easily identifiable the U-bolt is round/circular around the top of the leaf spring.
