Modified Timken Unit Bearings are a proven choice for off-road builders upgrading 2005+ Super Duty front ends. The factory Timken bearing ensures OE-level durability and longevity, while the 8-lug 6.5" bolt pattern modification allows for broader wheel compatibility. The included ABS Port Block Off fitting eliminates the need to retain factory ABS components—perfect for race rigs, trail crawlers, and custom builds that prioritize strength and simplicity.
