ReadyLIFT 3.5" Rear Spacer Kit

 

The ReadyLIFT 3.5 Inch Rear Spacer Kit is built for heavy-duty coil spring rear suspension trucks that need meaningful rear height for towing stance, hauling support, or a balanced lifted look. It gives customers a purpose-built way to add rear lift without stacking multiple spacers or replacing the entire rear suspension system. The design is well suited to trucks that carry equipment, tow trailers, or need to sit correctly after a front leveling or lift upgrade.

A rear coil spring spacer can make a major difference in how a heavy-duty truck looks and works. When the front of a truck has been raised, the rear can appear too low under cargo or trailer weight, especially with bed accessories or overland equipment installed. This spacer kit helps bring the rear ride height back into a more useful position, giving the truck a cleaner side profile and a stance that better fits demanding use.

ReadyLIFT uses fabricated steel rear coil spring spacers for this kit, giving the component a strong, purpose-built structure for the rear suspension location. The spacer installs with the factory rear coil spring layout and is designed to provide 3.5 inches of rear lift on the supported application. That amount of height makes the kit a strong choice for customers who need more rear rake than a mild leveling correction can provide.

The one-piece spacer approach is valuable because it avoids the unsafe look and compromised feel of stacked spacer combinations. Customers get a more complete rear height solution that is matched to the truck's coil spring suspension design. For towing and hauling, this helps the truck maintain a better working attitude while still retaining the original ride layout that heavy-duty owners expect.

This rear spacer kit is especially useful for trucks carrying bed racks, cargo drawers, tools, fuel tanks, rooftop tents, or other equipment that can make the rear suspension sit lower than intended. It can also complement front leveling changes by bringing the rear back into balance visually and functionally. Fitment should always be matched to the correct single-rear-wheel, non-camper-package rear coil spring application before installation.

Whether customers are upgrading for towing, hauling, overland equipment, or restored rear rake, the ReadyLIFT 3.5 Inch Rear Spacer Kit delivers substantial rear height in a purpose-built coil spring spacer design. Now Available at LEER!
