Enhance your truck's lift and towing capacity with durable cast iron blocks.
The ReadyLift Leaf Spring Block Kit is designed for specific model applications, providing a robust solution for enhancing the lift of your truck. Constructed from high-quality cast iron, these blocks are engineered to replace lightweight extrusions, ensuring durability and stability. The kit includes two rear blocks, four U-bolts, and all necessary hardware for installation, making it a comprehensive solution for your suspension needs.
This 3-inch block kit is compatible with both classic and new body style 6-lug GM trucks, including 2007 and newer 2WD and 4WD models equipped with OEM 1.25-inch blocks. By removing the factory block, users can achieve an additional inch of rear lift, which is particularly beneficial for towing and hauling applications. The built-in locator pin ensures proper alignment during installation, enhancing the overall performance of your vehicle.
ReadyLift's design philosophy emphasizes functionality, allowing for a slight rake that improves the truck's stance while maintaining compatibility with existing suspension leveling kits. With an estimated installation time of about one hour, this block kit is a practical choice for those looking to improve their truck's capabilities without extensive modifications.
