The GPM MAM4025TSH is a precision engineered servo saver for ARRMA MOJAVE 4S, manufactured from 7075 aluminum to improve steering durability over the original plastic unit. This direct-mount servo saver is built to withstand repeated impacts while maintaining accurate steering input. Service access is retained for quick removal and refit during setup or repairs, and the included 25T spline saver integrates with standard steering linkages.
