This 50T steel spur is a service replacement compatible with the Axial Racing EXO platform and carries the model code EX050TS. It is suitable when the original plastic or fatigued metal spur shows looseness, chipped teeth, or inconsistent engagement.
Sold as 1 pcs, the 50-tooth steel unit focuses on maintaining steady tooth contact and reducing wear in low-speed, high-torque crawling and trail rigs. It can lower the rate of spur wear versus softer alternatives and helps keep gear mesh consistent under load.
Fitting notes: verify correct pinion-to-spur mesh and existing shim arrangement, re-use the chassis' original orientation and fixings, and ensure the gearbox turns freely before sealing. Carry out a low-speed check run after installation to confirm smooth operation and correct motor and ESC behaviour.
