  • ReadyLIFT OEM-style rear block kits are available for the 1988-1998 2WD & 4WD 6-lug and 2000-2010 GM 2500HD/3500HD single rear wheel pickups. These Rear Block Kits include two (2) 1" Rear Blocks, four (4) E-Coated U-Bolts, eight (8) Nuts and Washers and will safely lift the rear of your 1988-1998 2WD & 4WD 6-lug and 2000-10 GM HD trucks 1". Based on OEM designs and never made out of light-weight extrusions, our 1" GM Blocks are made from cast iron just like the factory blocks, ensuring maximum strength and reliability. ReadyLIFT Block Kits will put a slight rake back in your truck for hauling or towing and are designed to work with your ReadyLIFT Suspension Leveling Kit. Like all ReadyLIFT products, these block kits come with our Lifetime Warranty. Note: Single Rear Wheel Only (will not fit Dually)

  • Tire Size Note: ReadyLIFT wheel and tire fitment recommendations are typically based on Wheel Pros wheels and Nitto tires. Due to product differences among tire manufacturers, tire specifications and dimensions including, but limited to, overall diameter, rolling diameter, tread width, aspect ratio, lug pattern, sidewall construction and inflation pressure, will vary meaningfully by tire and wheel manufacturer. Every tire and wheel combination should be test fit prior to installation. Consult your local installer to learn more about the right tire fitment for your application.

    Ride Quality Note: When lifting a vehicle and installing aftermarket wheels and tires, a tire manufacturer's construction and material quality can alter vehicle ride quality. When increasing a vehicle wheel and tire size, most larger aftermarket truck and SUV tires are 10-ply (or more) E tires compared to typical OEM 6-ply C tires. This more rigid sidewall construction increases the perception of suspension stiffness often described as ride harshness. The ride, handling, traction, noise, fuel economy, and wear differences between All-Season, All-Terrain, Mud-Terrain, or Trail-Terrain type tires can be significant. Please take into account tire and wheel choice will generally have a meaningful impact on the ride & handling experience.
