Kyosho LA402-04 - Gear Diff Shaft (2pcs) for LAZER ZX7.5  [KY-LA402-04]

Gear Diff Shaft for LAZER ZX7.5

This replacement gear diff shaft is supplied as a pair and intended for use in the LAZER ZX7.5 differential assembly. It serves as a direct wear item for rebuilding or refreshing the internal gear diff when shafts show play or wear from regular use.

Compatibility is limited to LAZER ZX7.5 models that use the same internal gear diff layout, confirm fitment against your chassis before installation. Two pcs are included in the pack to cover both sides of a standard gear differential.

Installation notes: this is a scale RC accessory, replace the shafts during a differential service using basic disassembly, clean the diff internals, inspect gears and bearings, then reassemble with correct spacing and grease. Proper seating of the shaft prevents binding and helps restore expected diff behaviour.

Tuning role: swapping worn diff shafts can reduce endplay and improve predictability of differential engagement; combine shaft replacement with inspection of spur gear, pinion gear mesh and bearing condition for best results.
