LAZER ZX7.5 Differential Gear Replacement Kit - LA402 by Kyosho  [KY-LA402]

LAZER ZX7.5 differential internals

This is an RC-scale differential gear set made for the LAZER ZX7.5 platform, supplied as a direct spare to restore or refresh a worn differential assembly. The LA402 kit supplies the internal gears needed to maintain reliable torque transfer within the differential housing for 1/10 electric on-road use.

The set is offered as replacement internals rather than a complete differential case, so confirming fit with the LAZER ZX7.5 chassis is the primary planning step for a swap. Installing new gears can reduce play and bring gear engagement back to a consistent state, which supports predictable handling under cornering and acceleration loads.

Installation notes: inspect mating surfaces and bearings for wear prior to assembly, set correct mesh and backlash when refitting the differential, and choose differential oil or grease that matches your tuning aims. Once correctly installed, the gear set helps deliver repeatable differential action for consistent on-track behavior.
