LAZER ZX7.5 Compatible Center Diff Cap - Kyosho LAW86 (Aluminum)  [KY-LAW86]

Machined aluminum replacement cap for ZX7.5

The Kyosho LAW86 aluminum center differential cap is an aftermarket replacement intended for the LAZER ZX7.5 center differential assembly. It functions as the closure plate to retain internal gears and bearings, keeping alignment and component positions stable during use.

Fitment is specific to the LAZER ZX7.5 diff layout; do not presume compatibility with other chassis or later/earlier generations without checking dimensional match and mounting holes. This cap corresponds to the ZX7.5 original screw pattern.

For installation, service the diff as usual: remove the existing cover, inspect and clean the gearset and bearings, lay components in place, then mount the aluminum cap and secure with the original screws tightened to the recommended torque. Take care to avoid overtorquing and verify the diff spins freely after assembly.

While the cap improves mechanical retention and consistency, any change in diff behavior is driven by internal adjustment and lubricant choice rather than the cap itself. Replace it during routine rebuilds or when the OEM cap is worn or damaged.
