ReadyLIFT 4" Rear Lift Block Kit

 

The ReadyLIFT 4 Inch Rear Lift Block Kit gives full-size and heavy-duty truck owners a stronger rear stance for towing, hauling, work use, and balanced lifted builds. It is made for customers who need more rear ride height than a mild block or leveling correction can provide, but still want a straightforward rear leaf spring solution. The kit helps the rear of the truck sit higher and more confidently without replacing the entire suspension system.

A 4 inch rear block can be useful when a truck has been leveled in front, outfitted with cargo equipment, or built around towing and overland use. The added height helps restore rear rake and improves the truck's visual balance from front to rear. For trucks that carry gear or pull trailers, the taller rear profile can make the vehicle look and feel more prepared for the job.

ReadyLIFT uses OEM-style rear block engineering with heavy-duty cast iron or fabricated steel construction depending on the application. Confirmed kits include longer E-coated U-bolts and hardware so the axle can be secured with parts matched to the block height and selected truck. Integrated locating features and, on certain applications, bump stop landing designs help the rear suspension upgrade work with the truck's factory layout.

This 4 inch height is a strong choice for customers building a lifted truck that still sees daily use. It can complement front leveling changes, larger tire packages, bed racks, camper-style accessories, and work equipment without turning the rear suspension upgrade into a full system overhaul. Customers who want more rake for towing or a taller rear profile for a suspension build can use this kit as a focused rear height solution.

Because the kits cover different full-size and heavy-duty truck applications, fitment must be matched to the selected vehicle and driveline layout before installation. Some trucks require a specific block shape or hardware package, and certain Super Duty applications require the correct choice for the driveshaft configuration. That application-specific approach helps preserve axle alignment and keeps the installation more predictable than a generic block setup.

Whether customers are upgrading for towing stance, work truck capability, cargo support, or a taller lifted profile, the ReadyLIFT 4 Inch Rear Lift Block Kit delivers substantial rear height with OEM-style suspension construction. Now Available at LEER!
