ReadyLIFT Suspensions lift kit for the 2019-2021 Silverado/Sierra 1500 4WD provides 4" of front lift and includes a 3" rear lift block for a nice level but lifted stance. 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 a true 4 inches of front lift. 69-3940 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). This kits provides a safe amount of lift without exceeding the CV limits which works well within the OEM tolerances.

GMC Sierra can only fit up to a 295/55-20 tire due to fender well restrictions.

This all-new no-cut kit includes new tubular steel upper control arms with adjusted ball joint pivot angles and maintenance-free TCT pivot bushings. These new 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 and aids towing or hauling payload.

Note: NOT intended for off-road use or abuse.
