Differential Bevel Gear Replacement for LAZER ZX7.5 - Kyosho LA402-02  [KY-LA402-02]

LAZER ZX7.5 Differential Bevel Gear Assembly Details

The Diff. Bevel Set is a replacement bevel gear assembly made for the LAZER ZX7.5 differential. Supplied as a service spare, it restores internal bevel gears that show wear or damage and supports routine drivetrain maintenance and tuning.

Fitment and role: the kit installs into the LAZER ZX7.5 differential case and engages with existing spider gears and the ring gear to carry torque through the diff unit. It is intended to return consistent rotation and diff behavior without the expense of replacing the whole differential.

Installation notes: disassembly of the differential is required to access the bevel gears, including removal of the diff cover and carriers. Inspect spider gears, thrust washers, and ball bearings for wear during the replacement and confirm gear mesh and backlash after refit to avoid binding problems.

Tuning considerations: installing new bevel gears can influence torque transfer during acceleration and cornering; verify ring and pinion contact patterns and perform measured test runs to assess handling changes. Adopt typical RC setup routines when adjusting diff preload or lubricant selection to maintain consistent results.

This Kyosho LA402-02 Diff. Bevel Set is provided as a direct service spare for LAZER ZX7.5 users who need to renew differential bevel gears and preserve drivetrain reliability in competition or practice.
