Modified Timken 2005+ Ford Super Duty Unit Bearing – 8x6.5" Bolt Pattern
WA01055
The Modified Timken 2005+ Ford Super Duty Unit Bearing is the gold standard upgrade for builders converting a Dana 60 or building custom steering axles for rock crawlers, rock bouncers, Ultra4 race cars, and hardcore trail rigs. Starting as a genuine Timken hub assembly, each unit is precision-modified in-house to eliminate traditional spindle and wheel-bearing maintenance while delivering massive load capacity and proven competition durability.
Each assembly is precision-machined to a standard off-road 8 on 6.5" wheel bolt pattern, fitted with heavy-duty 9/16" wheel studs for superior clamping force, and pre-installed with an ABS port block-off fitting. Designed to pair seamlessly with custom Dana 60 builds, Reid Racing Super Kingpin knuckles, and Crane Axle steering systems, this sealed hub assembly provides a reliable, bolt-on wheel-end solution that makes trailside servicing fast and effortless.

FAQ
1. Why convert a Dana 60 from traditional spindle hubs to a 2005+ Super Duty unit bearing?
Traditional Dana 60 hubs require regular maintenance, including greasing wheel bearings, setting spindle nut preload, and replacing inner wheel seals. Converting to a 2005+ Super Duty unit bearing provides a completely sealed, maintenance-free hub assembly with higher load capacity. If a bearing ever fails on the trail or in the pits, the entire unit can be swapped out in minutes as a single bolt-on assembly.
2. Is this a genuine Timken bearing assembly?
Yes. Every hub starts as a brand new, genuine Timken 2005+ Ford Super Duty unit bearing assembly. It is then precision-machined in-house to an off-road standard 8 on 6.5" wheel bolt pattern and fitted with upgraded wheel studs.
3. Why is the factory ABS sensor port blocked off?
Factory Ford Super Duty trucks use an ABS sensor plugged into the top of the unit bearing. Because custom rock crawlers, Ultra4 cars, and competition buggies do not use factory ABS systems, leaving the sensor port open or using a broken sensor can allow water, mud, and debris to contaminate the internal bearing grease. We install a billet ABS block-off fitting to permanently seal and protect the internals.
4. What size wheel studs come installed in this unit bearing?
We install heavy-duty 9/16" wheel studs into the newly machined 8 on 6.5" bolt circle. These provide superior clamping force and shear strength compared to smaller wheel studs when running heavy beadlock wheels and 40- to 47-inch tires.
5. Will this unit bearing fit Reid Racing or Crane Axle steering knuckles?
Yes. This modified unit bearing is designed as a direct drop-in fit for custom steering knuckles built around the 2005+ Ford Super Duty hub profile, including Reid Racing Super Kingpin knuckles, Crane Axle Magnum Knuckle systems, and custom fabricated axle end cups.
