Product Overview
The ReadyLIFT 4" Rear Lift Block Kit lineup is engineered for truck owners looking to increase rear ride height, restore factory rake, improve towing performance, and compensate for added cargo weight without installing a complete suspension lift system. Designed for select Ford Super Duty, Ford F-150, Chevrolet Silverado, GMC Sierra, and Ram 3500 HD applications, these OEM-style rear block systems provide a durable and vehicle-specific solution for rear suspension enhancement.
ReadyLIFT rear block kits utilize heavy-duty cast iron or fabricated steel construction depending on application and feature integrated locator pins, bump stop landing pads, and vehicle-specific U-bolts engineered for proper axle alignment and long-term durability. These systems are commonly used on leveled trucks, towing rigs, overland builds, and heavy-duty work trucks requiring additional rear suspension height and load support.
Available for multiple driveline configurations including 1-piece and 2-piece driveshaft Super Duty applications, the ReadyLIFT 4-inch rear block systems help maintain suspension balance while improving towing stance and overall truck appearance. Now Available at LEER!
