This aluminium saver kit upgrades the stock plastic servo saver and tie rods on the TAMIYA CW-01 Lunch Box chassis with machined metal components intended to improve durability and steering feel. The assembly pairs a 25T high-torque saver with aluminium tie rods to reduce flex and wear where plastic parts may fail.
Compatibility targets the CW-01 (Lunch Box) chassis and requires servos with a 25T spline for correct engagement. The part functions as the mechanical interface between the servo output and steering linkage, protecting internal servo gearing while maintaining steering precision.
Installation: remove the original saver and tie rods, reuse any appropriate hardware, then mount the aluminium saver on the servo spline. Check spline engagement, steering travel, and tie rod geometry to ensure no binding. There are no electronic modifications needed for fitment.
Maintenance: metal parts lower elasticity compared with stock items but still need periodic inspection for thread tightness and alignment. Use thread-lock on metal-to-metal fasteners where recommended and inspect after impacts. The tie rods provide a consistent baseline for steering trim and toe adjustments.
