Kyosho LAW87 - Plastic Diff. Gear Case Set (ZX7.5)  [KY-LAW87]

Plastic diff case for ZX7.5

This plastic differential gear case set is a direct replacement component specified for the ZX7.5 designation, intended as an RC-scale spare for differential assembly repairs and routine maintenance. The set provides the housing that locates the internal gears and maintains mesh relationships inside the differential assembly.

Designed for use within the ZX7.5 assembly, the case focuses on correct alignment rather than altering gear ratios or performance characteristics. When replacing the case, inspect internal gear teeth, transfer any existing walk-through items such as shims or spacers, and verify that bearings seat flush before final assembly to preserve concentricity.

Installation overview: remove the differential assembly from the chassis, separate the halves, move the gear set and any shims into the new case, then reassemble while checking lateral play and gear mesh. This component is intended for maintenance and repair workflows and should be handled as an RC-model replacement part rather than an upgrade that changes drivetrain behavior.

Use this set when the original case is worn or damaged to restore correct gear positioning and facilitate accurate gear mesh checks during regular upkeep.
