ReadyLIFT OEM-style rear block kits are available for model specific applications. These Rear Block Kits include two (2) 3-Inch Rear Blocks, four (4) E-Coated U-Bolts, eight (8) Nuts and Washers and will safely lift the rear of your truck an additional 1-Inch to 3-Inch depending on the application.
Based on OEM designs and never made out of light weight extrusions, our 3-Inch GM Blocks are made from cast iron and have anti-rotation ears built-in. Fits 1999-2021 classic and current body style 6-lug model GM trucks.
Models with 1.25-Inch OEM blocks will want to take advantage of the additional 1.75-Inch of lift for towing and hauling, particularly when using a front leveling kit. 1999-2006 4WD trucks will replace the factory 2-Inch block for 1-Inch of additional lift.
This kit eliminates the dangers of having to stack blocks which may be illegal in some states. ReadyLIFT Block Kits will put a slight rake back in your truck for hauling or towing and are designed to work in concert with your ReadyLIFT Suspension Leveling Kit.
