For owners of older NT series cars, the XRAY 385665 steel 65T spur gear set helps preserve original performance while improving durability. The kit pairs a machined 65T steel spur with a composite adapter to deliver reliable meshing and extended service life.
The steel construction resists wear under load and maintains consistent tooth engagement. When used with the included composite adapter the assembly reduces drivetrain play and keeps power delivery steady during driving sessions. This is a practical choice when refurbishing a classic RC or tightening up a race setup.
Made to match the older version NT series mounting geometry, the spur gear kit installs with the supplied hardware for a straightforward swap. Minimal adjustment is required so you can return to track or trail duty quickly.
