XRAY 355087 Aluminium Differential Pin Set for Precision Builds  [XR-355087]

Low-mass aluminium pins from XRAY for centre differentials

The XRAY 355087 Aluminum Differential Pin Set is intended to replace heavier pins in large center differentials, improving rotational efficiency. These precision-ground polished aluminium pins are compatible with the internal satellite gears used in large center differential #355013 and feature steel inserts to increase contact durability under heat.

Reduced inertia, cleaner drivetrain response

With approximately 30% less mass than steel pins, the aluminium pins reduce rotating inertia inside the differential. This reduction helps the drivetrain change speed with less lag and supports steadier handling across repeated laps or long practice sessions.

Steel insert reinforcement for tough conditions

The pins use steel inserts at the wear points, providing strength where it matters while keeping overall mass down. That makes the XRAY 355087 a good option when diffs run hot or are subjected to heavy use.

For precision builders who value lower rotating mass and reinforced contact areas, the XRAY 355087 offers a pragmatic balance of weight saving and longevity.
