The XRAY 362370 composite inline hub is built for drivers wanting accurate rear drive setup on the XB4'21. Use this hub to adjust bevel gear alignment and height so the rear end responds more predictably during corner exit and acceleration.
Made for the rear HS bulkhead on the XB4'21, this composite hub lets you change the rear differential geometry. There are six discrete height positions, letting you move the bevel drive within a 5mm span to tailor traction and roll behaviour.
This part is intended for the XRAY XB4'21 line and suits racers who swap setups between carpet, asphalt and loose surfaces. Proper alignment from this hub helps reduce binding and improves overall drivetrain efficiency.
