The 26-3105 5" rear block kit will safely lift the rear an additional 4" after removing the factory 1" block. Based on OEM designs and never made out of light weight extrusions, ReadyLIFT GM Blocks are made from cast iron and have built-in anti-rotation ears. Fits 2014-2018 new body style 6-lug model GM trucks. New models with OEM 1.25" blocks will want to take advantage of the additional 4" of lift for towing and hauling, particularly when using a front leveling kit. Eliminates the dangers of having stacked 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. Like all ReadyLIFT products, these block kits come with our Lifetime Warranty.
NOTE: ReadyLIFT recommends the use of the 67-3809 Rear Shock Extension Kit or longer shocks when using a lift block of this height. The 5" Rear Block Kit works great with our GM 6-lug 2.25" front leveling kits to achieve a mild lift stance with a slight rake.
