Kyosho LA407 Aluminum Center Shaft (95/7075) for LAZER ZX7.5  [KY-LA407]

Aluminum center shaft for LAZER ZX7.5

This LA407 aluminum center shaft is an RC-scale replacement part designed specifically for the LAZER ZX7.5 drivetrain. Machined from 95/7075 grade aluminum, the shaft is intended to maintain straightness and reduce deflection under typical 1/10 touring car loads.

Fit and compatibility are focused on the LAZER ZX7.5 platform; verify part fitment against your chassis before final installation. The shaft's role in the driveline is straightforward: it locates the center gear train, transfers torque between gearbox sections, and affects driveline backlash and runout.

Installation notes: inspect surrounding bearings and gear faces for wear prior to fitting, replace damaged 走珠軸承 if needed, and ensure the shaft seats fully without binding. Use appropriate thread locking on fasteners where thread engagement passes through rotating elements, and avoid over-tightening mounting screws to prevent bearing preload.

Tuning role: upgrading to a stiffer, precision-machined center shaft can reduce unwanted flex and improve consistency during acceleration and braking phases, which helps when dialing in differential and suspension settings. Expect incremental improvements in drivetrain feel rather than dramatic changes in lap time.
