ReadyLIFT rear block kits are available for specific model applications.
These Rear Block Kits include two (2) Rear Blocks, four (4) E-Coated U-Bolts, and eight (8) Nuts and Washers.
The 5" rear block kit 26-3950 will lift the rear an additional 4" after the factory 1" block is removed.
Based on OEM designs and never made from lightweight extrusions, ReadyLIFT GM Blocks are constructed from cast iron and feature built-in anti-rotation ears.
Fits GM trucks with a new body style 6-lug model from 2019-2023.
New models with OEM 1.25" blocks will want to take advantage of the additional 4" of lift for towing and hauling, especially when using a front leveling kit.
Eliminates the dangers of stacked blocks which may be illegal in some states.
ReadyLIFT Block Kits will restore a slight rake back in your truck for towing or hauling and are designed to work in concert with your ReadyLIFT Suspension Leveling Kit.
Like all ReadyLIFT products, these block kits come with a Lifetime Warranty.
NOTE: ReadyLIFT recommends using the 67-3809 Rear Shock Extension Kit or longer shocks when using a lift block of this height.
The 5" Rear Block Kit works well with our GM 6-lug 2.25" front leveling kits to achieve a mild lift stance with a slight rake.
NOTE: This GM 1500 kit is NOT COMPATIBLE with vehicles equipped with rear composite mono-leaf springs.
The mono-leaf is easily identifiable as 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.
