Product Details
Part No. 66-3002
Warranty Details (1 YR REPLACEMENT IF DEFECTIVE)
ReadyLift(R) OEM style rear block kits are now available for model specific applications. Based on OEM designs and never made out of light weight extrusions our 2 Inch GMC Sierra or Chevy Silverado Rear Blocks are made from cast iron and have Anti-Rotation ears built-In. Fits classic and new body style 6-lug model GM trucks. New model 2007-UP 2WD and 4WD Trucks with OEM 1.25 Inch blocks will want to take advantage of the additional 1 Inch of lift for towing and hauling, particularly when using a front leveling kit. This block is 2.25 Inch which when removing the factory 1.25 Inch block, results in an increased rear lift of 1 Inch. ReadyLift(R) 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(R) Suspension Leveling Kit.

Product Features:
  • Made From Cast Iron/Not Light Weight Extrusions
  • Built In Locator Pin/Not Pressed In
  • Puts Rake Back In Your Truck For Towing/Hauling
  • Installation Time Is About An Hour
