Tamiya CW-01 (Lunch Box) 25T Aluminium Hi-torque Servo Saver & Tie Rod LB025TM by GPM  [LB025TM]

25T aluminium servo saver and tie rod for CW-01 upgrades

This aluminium hi-torque servo saver with a matching aluminium tie rod is made for the Tamiya CW-01 (Lunch Box) geometry and is supplied as a single serviceable set. It replaces standard plastic savers to cut flex under load and to transmit steering input with less lost motion, while the aluminium tie rod stiffens the connection between the servo output and the steering knuckles.

The saver uses a 25T spline interface that fits many hobby servos with 25-tooth splines, and the aluminium build emphasises rigidity and repeatable steering feedback rather than damping. Confirm that your servo spline count and horn clearance match the CW-01 layout before finishing installation.

Installation notes: remove the stock servo saver, align the 25T spline with the servo output, install the servo horn and secure using your normal hardware, then attach the aluminium tie rod to the steering linkage and sweep the steering to check for binding. Leave the small free-play recommended by your steering geometry to avoid sending shock loads straight into the servo.

On-track setup tips: the assembly sharpens steering response; if you notice extra feedback or occasional binding, re-check horn orientation and link length, and use gentle trim changes at the transmitter to recenter steering.
