ReadyLIFT SST 4.0-Inch Lift Kit for 2019–2023 GM 3.0L LM2/LZ0 Silverado/Sierra Models

Description

Fits: 2019 thru 2023 Chevy Silverado/GMC Sierra 1500 LM2/LZ0 Duramax Diesel 

 ReadyLIFT introduces the latest 4” SST Lift Kit for 2019-2023 Chevy Silverado and GMC Sierra 1500 trucks. The new kit is compatible with Adaptive Ride Control Suspension (ARC) and replaces the previous model 69-3940. The SST Lift Kit provides a reliable lift solution that achieves an aggressive and functional lift without compromising drivability or handling.

The 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. This kit provides the right amount of lift without pushing 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 no-cut kit includes new tubular steel upper control arms with optimized ball joint pivot angles and maintenance-free TCT pivot bushings. The upper control arms of the 4″ SST Lift Kit ensure proper suspension geometry.

For the rear, ReadyLift includes 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, the truck will have a very subtle rake that looks great with the body lines even while towing or hauling payload.
