2017-2025 Superduty SRW 6.5" Rear Block Kit (26-27650 (26-2765)

The ReadyLIFT 6.5-inch Tall Tapered Block Kit is an OEM-style rear block designed for 2017-2025 Ford Super Duty SRW F250/F350 models equipped with a one-piece driveshaft. These blocks are constructed from OEM-style cast iron, not lightweight extrusions, and feature integrated factory-style bump stop landings. The kit is an ideal tow package upgrade for stock, leveled, or lifted trucks, as it puts a slight rake back in the truck for improved hauling or towing capabilities, and is designed to work with any ReadyLIFT Suspension Leveling Kit.

Notes
