ReadyLift - 5" Rear Block Kit (1-Piece Driveshaft) - 2011-2016 Ford Super Duty - 66-2025

5" rear lift block kit for 2011-2016 Ford Super Duty single-rear-wheel trucks with a one-piece rear driveshaft.

ReadyLIFT OEM-style rear block kits replace the factory blocks to safely add rear lift and restore a slight rake for hauling or towing. Cast from OEM-style iron with integrated OEM-style bump stops, these 5" blocks are built to work alongside a ReadyLIFT front leveling kit and make an ideal tow-package upgrade for stock, leveled, or lifted trucks.

Fits: 2011-2016 Ford F-250 / F-350 Super Duty 2WD/4WD, single rear wheel only (not dual-rear-wheel), with a one-piece rear driveshaft. Not intended for vehicles equipped with a Service Axle. Actual lift gained varies with the factory block being replaced.

Features

• 5" cast-iron OEM-style rear lift blocks with integrated bump-stop landings
• Restores a mild rake for towing and hauling
• Designed to pair with a ReadyLIFT front leveling kit
• Backed by the ReadyLIFT Limited Lifetime Warranty

Kit Includes

• Two (2) 5" rear lift blocks
• Four (4) 16.5" long E-coated U-bolts
• Eight (8) nuts and washers

Notes

Single-rear-wheel trucks only; one-piece rear driveshaft only; not intended for vehicles with a Service Axle. Not for use with air spring/load-leveling kits that attach to the bump-stop tangs; doing so voids the block warranty. Estimated installation time about 1.8 hours (excluding alignment).
