XRAY 302063-K T4 Aluminum Adjustable Ball-Bearing Hub Set Black (2) - Race Grade  [XR-302063-K]

Precision Aluminum Hubs Built for the XRAY T4

The XRAY 302063-K T4 Aluminum Adjustment Ball-Bearing Hub is a purpose-built upgrade for the XRAY T4 lineup. Machined from 7075 T6 aluminum, these hubs outlast stock composite parts while reducing drivetrain drag so your setup runs cleaner and more efficiently on race day.

Benefits Over Standard Composite Hubs

Aluminum hubs deliver tougher wear resistance and tighter tolerances than molded parts, which helps maintain alignment under load and cuts rolling resistance. That reduced friction leads to more predictable handling and less energy loss through the drivetrain.

Core Features

• Made from 7075 T6 aluminum for improved strength
• Black finish for a clean, race-ready look
• Direct drop-in replacement for stock composite hubs
• Includes a matched pair (2 hubs)
