Rear Suspension Lift Blocks. The Zone Offroad 5-Inch Rear Lift Blocks are engineered to raise the rear suspension of leaf spring trucks by 5 inches, improving ground clearance and vehicle stance. These blocks address suspension height differences and optimize drivetrain angles, which are essential for off-road performance and load handling efficiency.

Construction and Appearance. Made from durable cast iron with a black e-coating finish, these lift blocks provide excellent corrosion resistance and long-term durability. Manufactured in the USA, they are precision CNC-machined to ensure accurate pin placement and feature a tapered design that helps correct pinion angles, enhancing driveline geometry.

Installation. Installation is straightforward for anyone experienced with suspension systems, requiring no drilling as the blocks utilize standard 3/4-inch pins for mounting. Users should verify model compatibility, especially Dodge Ram 3/4 ton and 1 ton trucks that require an additional conversion part to adapt factory blocks for single-pin use.

Application. Designed specifically to fit 2003-2011 RAM 2500 models. Note that Dodge 3/4 ton and 1 ton trucks in this range need a conversion kit (Zone part 01599) to convert factory 3-pin blocks to single-pin configuration.
