Designed as an aftermarket swap, this 25T servo saver fits ARRMA Mini series models and the specified LOSI 1/12 vehicles. Made from 7075 aluminium, the design targets increased strength and more consistent steering input while an internal spring soaks up impacts to protect gearbox teeth.
The unit includes pre-assembled fastenings; use a medium-strength threadlocker on the screws to maintain secure fit under vibration. The 25T spline note is included in the source; always check spline compatibility with your servo horn.
Use this aluminium saver as a direct replacement or as an upgrade to reduce wear and tune steering characteristics during both competitive and casual driving. Verify the model list below for precise compatibility.
