ReadyLift® OEM style rear block kits are now available for model specific applications. These Rear Block Kits include (2) Rear Blocks, (4) E-Coated U-Bolts, (8) Nuts and Washers and will safely lift the rear of your Truck an additional 1” to 3” depending on application. Based on OEM designs and never made out of light weight extrusions our 3" GM Blocks are made from cast iron and have Anti-Rotation ears built-In. Fits 1999-2013 classic and new body style 6-lug model GM trucks. New models with OEM 1.25" blocks will want to take advantage of the additional 1.75" of lift for towing and hauling, particularly when using a front leveling kit. 1999-2006 4wd trucks will replace the factory 2" block for an additional 1" of lift. 1999-2006 2wd trucks will gain the full 3" of lift. Eliminates the dangers of having to stack blocks which can 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. Installation time is approximately 1+ hours.
NOTE: For '99-UP GM 1500 Trucks which will see off road use or conditions which can cause excessive rear suspension cycling while using the factory rear shock, ReadyLift recommends the use of the 67-3809 Rear Shock Extension Kit .
The ReadyLift 3" Rear Block Kit works great with our 66-3085 GM 6-lug 2.25" front leveling kit to achieve a mild lift stance with a slight rake put back in or with our popular 66-3050 Torsion Keys and 66-3000 Torsion Keys Leveling Kits to work as the perfect towing package.
