2017-2023 Superduty 6" Rear Block Kit with Carrier Bearing Spacer (66-2761)

ReadyLIFT OEM-style rear block kits are engineered specifically for 2017-2025 Ford Super Duty models with a two-piece drive shaft. These 6.0-inch fabricated steel Flat Rear Block Kits are built based on OEM designs and are never made from lightweight extrusions. They feature integrated OEM-style bump stops and are designed to put a slight rake back in your truck for improved hauling or towing performance. This kit is an ideal Tow Package upgrade for stock height, leveled, or lifted trucks and works perfectly with a ReadyLIFT Suspension Leveling Kit.
