Kyosho LA405 Drive Joint Cup (ZX7.5) — Drive cup replacement for LAZER ZX7.5  [KY-LA405]

Drive Joint Cup for LAZER ZX7.5

This Kyosho LA405 Drive Joint Cup is an RC-scale replacement part designed specifically for LAZER ZX7.5 models. It serves as the interface between the drive shaft and the universal joint assembly, helping to locate the shaft and transfer torque cleanly within the drivetrain.

The text emphasises practical use: as a spare component it is intended for routine maintenance or repair after wear or impact. Fitment is limited to LAZER ZX7.5 as stated, and the part should be inspected for wear or deformation before installation to avoid drivetrain runout.

Installation notes and tuning role: when replacing the drive cup, check the mating surfaces and any retaining pins or fasteners for damage, ensure concentric seating on the drive shaft, and verify free rotation of the joint after assembly. Small adjustments to drivetrain alignment can reduce vibration and improve smoothness, which helps consistent power delivery on electric on-road RC vehicles.
