For club racers and weekend tuners, the Yokomo Z2-500GM3A gear diff maintenance kit provides essential parts to keep YZ-2/4 diffs performing reliably. The kit is made to match the B-YZ2CAL3 and B-YZ2DTM3 chassis and supports routine rebuilds.
The resin cross pin included in this kit trims down rotating mass which can help the diff respond faster to load changes. That lighter component supports smoother operation and can assist in sharper corner exits.
Carefully produced for correct fit, this maintenance pack is compatible with B-YZ2CAL3 and B-YZ2DTM3 units, suitable for both maintenance cycles and pre-event servicing. It supplies dependable replacements for common diff wear items.
