ReadyLIFT 69-39400 4" SST Lift Kit 20-24 GM 3.0L Duramax LM2/LZ0

New truck with boring looks? Have no fear, ReadyLift is here with a 4" kit for the 2020-2023 Chevy Silverado and GMC Sierra 1500 with exclusive components making the kit compatible with available Adaptive Ride Control Suspension (ARC)! The 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. This 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 other kits on the market. This lift kit can easily allow for up to a 295/65-20 tire as shown here with XD Series Demodog 20x9 0 offset wheels (35x11.50 max). The kit provides the right amount of lift without exceeding the CV limits working within the OEM tolerances. (GMC Sierra can only fit up to a 295/55-20 tire due to fender flare wheel well restrictions.) This no-cut kit includes tubular steel upper control arms with optimized ball joint pivot angles and maintenance-free TCT pivot bushings. These upper control arms are an essential component of the 4" SST Lift Kit to ensure proper suspension geometry. For the rear, included are the 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 GM 1500 truck will have a very subtle rake that looks great with the body lines even while towing or hauling payload. IMPORTANT NOTES: This kit is NOT compatible with Trail Boss, ZR2, AT4, or AT4X. This GM 1500 kit is NOT COMPATIBLE with vehicles equipped with rear composite mono-leaf springs. The mono-leaf is easily identifiable – the U-bolt is round/circular around the top of the leaf spring. This kit only works with vehicles equipped with traditional steel leaf springs – identified by ‘square’ U-bolts. Use of Auto 4 Hi feature is not recommended. NOT compatible with 2019 Limited OLD Body Style. NOT intended for off-road use or abuse.
