ReadyLIFT OEM-style rear block kits are available for model-specific applications. These Rear Block Kits include two (2) Rear Blocks, four (4) E-Coated U-Bolts, and eight (8) Nuts and Washers. The 3" rear block kit will safely lift the rear an additional 2" after removing the factory 1" block. Based on OEM designs and never made out of lightweight extrusions, ReadyLIFT GM Blocks are made from cast iron and have built-in anti-rotation ears.

Fits 2025-2026 new body style 6-lug model GM trucks. New models with OEM 1.26" blocks will want to take advantage of the additional 3" of lift for towing and hauling, particularly when using a front leveling kit.

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.
