LAZER ZX7.5 Internal Gear Set for Differential - LA402 by Kyosho  [KY-LA402]

Internal gear set for ZX7.5

This RC differential gear set is intended for the LAZER ZX7.5 platform and functions as a spare-part solution to refresh a worn differential. The LA402 package contains the internal gears required to preserve reliable torque transfer inside the differential on 1/10 electric on-road models.

Presented as replacement internals, this set does not include a full differential case, so confirming LAZER ZX7.5 fitment is essential when planning a service. Renewing worn gears decreases internal lash and restores even gear engagement, which contributes to steadier handling when pushing the car.

Installation guidance: check bearing seating and mating surfaces for damage before assembly, establish correct mesh and backlash during reassembly, and pick differential oil or grease consistent with your tuning objectives. Properly installed gears support consistent differential behavior and improve component longevity.
