Maintaining vintage RC models is easier with replacement parts that match original quality. The XRAY 389178 metal gear set is made for the XRAY XMS01MG micro servo and helps sustain precise control in older M series vehicles.
Upgrading to metal gears improves resistance to wear and can deliver more consistent responses under load. This kit replaces the factory #389170 plastic gears and is chosen for longevity in frequent use.
The gears are intended to fit the XMS01MG micro servo directly, allowing a straightforward swap on vintage M series cars. Check gear engagement and servo travel after fitting to ensure optimal operation.
