LAZER ZX7.5 Diff. Gear Set LA402 for On-Road 1/10 by Kyosho  [KY-LA402]

Replacement differential gears for ZX7.5

This RC differential gear set is intended for the LAZER ZX7.5 platform and is supplied as a spare to restore or refresh a worn differential assembly. The LA402 set contains the internal gears needed to preserve reliable torque transfer in 1/10 electric on-road applications.

Offered as internal replacements rather than a full differential case, compatibility with the LAZER ZX7.5 chassis should be checked before ordering. Installing fresh gears can tighten up internal play and restore consistent gear engagement, which supports predictable vehicle behavior during cornering and hard acceleration.

Practical advice: inspect bearings and contact surfaces for damage before fitment, ensure correct gear mesh and backlash during reassembly, and choose differential lubricant that aligns with your setup goals. When fitted correctly, the gear set contributes to dependable differential performance and repeatable handling results.
