The 3" rear block kit will safely lift the rear of your Silverado an additional 1" to 3" depending on the application. Based on OEM designs and never made out of light weight extrusions, their 3" Chevrolet blocks are made from cast iron and have anti-rotation ears built-in. Fits 2014-2021 classic and current body style 6-lug model Chevrolet trucks.

Models with 1.25" OEM blocks will want to take advantage of the additional 1.75" of lift for towing and hauling, particularly when using a front leveling kit. This kit eliminates the dangers of having to stack blocks. 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.

Note: 2019-UP trucks may need to trim off excess bolt length after installation.
