XRAY 309003 Ceramic Bearing Kit (12 pcs)  [XR-309003]

Ceramic Bearing Upgrade for XRAY X4 2025

The XRAY 309003 ceramic bearing kit gives the XRAY X4 2025 a direct upgrade path from stock steel bearings to lighter, low-friction ceramics. This 12-piece selection targets the main rotating points to deliver smoother rotation under load.

Advantages of Ceramic Components

Featuring Si3N4 silicon nitride ceramic balls, these bearings typically offer lower mass and increased resistance to corrosion and wear versus standard steel. That helps reduce rotational losses and keeps the drivetrain responsive.

Prepped for Track Use

Each bearing is degreased and receives a light coat of AeroShell Fluid 12 oil so they are ready to run after install. The initial lubrication helps preserve bearing life and maintain tight running tolerances.

Full Set for Key Points

With twelve bearings included, the set covers the key bearing positions on the XRAY X4 2025. Owners can expect improved drivetrain smoothness and reduced mechanical noise after swapping the stock bearings for these ceramic units.
