The Modified Timken 2005+ Ford Super Duty Unit Bearing is one of the most popular upgrades for builders converting a Dana 60 to modern unit bearings.

Whether you're building a rock crawler, Ultra4 car, rock bouncer, prerunner, trail rig, or custom axle assembly, 2005+ Super Duty unit bearings have become the gold standard for high-strength unit bearing conversions. Their massive bearing capacity, excellent parts availability, and proven durability make them a favorite among off-road builders looking to eliminate traditional spindle and serviceable hub assemblies.

Each unit bearing starts as a genuine Timken 2005+ Ford Super Duty hub assembly and is precision modified for off-road and custom axle applications. The hub is machined for an 8 on 6.5 wheel bolt pattern, fitted with heavy-duty 9/16" wheel studs, and includes an installed ABS port block-off fitting.

Designed for use with custom Dana 60 builds, Reid Racing knuckles, Crane Axle front ends, and Super Duty knuckle conversions, these modified hubs provide a reliable, race-proven solution for extreme off-road use.

Unit Bearings vs. Traditional Dana 60 Hubs

Tech Insight

Why do builders convert to 2005+ Super Duty Unit Bearings?

The 2005+ Super Duty hub assembly has become one of the most widely used components in modern Dana 60 conversions because it offers:

• Massive load capacity
• Excellent parts availability
• Reduced maintenance
• Simplified assembly
• Proven race durability
• Easy replacement when servicing

Instead of rebuilding traditional wheel bearings, races, seals, and spindles, the entire unit bearing can be replaced quickly and easily.

What is a Super Duty unit bearing conversion?

A Super Duty unit bearing conversion replaces traditional spindle-style wheel bearings with a sealed 2005+ Ford Super Duty hub assembly.

Why use a 2005+ Super Duty unit bearing?

The 2005+ Super Duty bearing is extremely strong, widely available, and proven in heavy-duty truck and off-road applications.

Is this a genuine Timken bearing?

Yes. This assembly starts as a genuine Timken unit bearing before being modified for off-road applications.

What bolt pattern does this use?

This unit bearing is machined for an 8 on 6.5 wheel bolt pattern.

Why are 9/16" studs used?

9/16" wheel studs provide increased clamping force and strength compared to smaller factory studs, making them popular for competition and off-road applications.

Can I use this with Reid Racing knuckles?

Yes. These modified unit bearings are commonly used with Reid Racing Super Kingpin and custom Dana 60 applications.

Why is the ABS port blocked off?

Most custom axle builds, race vehicles, rock crawlers, and competition rigs do not utilize factory ABS sensors. The included block-off fitting seals the unused port.

Are unit bearings stronger than traditional Dana 60 wheel bearings?

For many off-road applications, builders prefer unit bearings because of their durability, ease of service, and simplified design. Both systems have advantages, but modern unit bearing conversions have become extremely popular in the off-road industry.
