Kyosho LA402 - Diff. Gear Set (ZX7.5)  [KY-LA402]

Differential gear set for ZX7.5

This is an RC-scale differential gear set designated for the LAZER ZX7.5 platform, intended as a direct spare part to restore or refresh a worn differential assembly. The LA402 kit focuses on providing the internal gears required to maintain reliable torque transfer inside the differential housing on 1/10 electric on-road applications.

The set is presented as replacement internals rather than a complete differential case, so compatibility with LAZER ZX7.5 is the core consideration when planning a swap. Replacing worn gears can reduce slop and restore consistent gear engagement, which helps maintain predictable handling during aggressive cornering and acceleration.

Installation notes: inspect mating surfaces and existing bearings for wear before assembly, ensure proper mesh and backlash when reassembling the differential, and verify that differential oil or grease selection matches your tuning goals. The gear set plays a tuning role by enabling consistent engagement and repeatable differential action once correctly fitted.
