For racers wanting to fine tune XB2 and XB4 drivetrains, the XRAY 966080 CH-Clip 8 Grinded set is a compact upgrade. These clips sit in the differential to improve engagement and reduce irregular movement.
The XRAY 966080 pieces are ground to remove surface imperfections and to improve mating geometry. That results in less friction and a more repeatable response from the differential under load.
This two-piece set is compatible with XB2 and XB4 differentials and fits with basic disassembly. It is designed for easy swapping so you can return to track testing quickly.
