Crane Axle Rear Unit Bearing Adapter Cup Assembly (Pair)

Crane Axle Rear Super Duty Unit Bearing Cups make it easy to build a solid axle rear end using 2005+ Ford Super Duty Unit Bearings. Designed for performance and reliability, these weld-on cups replace the traditional spindle setup found on rear axles, offering a simpler, cleaner, and stronger solution for custom off-road and race applications.

By switching to this setup, you eliminate the need for messy gear oil or greased wheel bearings, and avoid the common issues of broken shafts stuck in the spindle bore or bent spindles.This design simplifies axle maintenance, increases strength, and fits all major demands needed in off-road environments.

Key Benefits:

• Simplified Maintenance: No more packing bearings or adjusting spindle nuts. The unit bearings make servicing faster and cleaner.
• Increased Strength: Supports larger 40-spline (or greater) axles with a robust weld-on design.
• Clean, Dry Axle Setup: No greasy bearings or oil contamination to worry about.
• All Hardware Included: Cups come complete with mounting hardware for your build.
