High-Precision 21T Aluminum Pinion

The XRAY 365721 pinion gear is built for tuners who want predictable drivetrain behaviour. This 21T pinion uses 7075 T6 aluminum and a hard-coat surface to combine lightness with improved wear resistance. Its design promotes steady engagement and quieter running under load.

Precision Machining for Smooth Running

Manufacturing processes yield finely shaped teeth that run true and reduce vibration, improving drivetrain efficiency. The internal thread configuration is user-friendly and makes fitting straightforward for quick gear swaps.

Easy Selection in the Pits

Each gear is marked with its tooth count for fast selection during setup changes. Available in several sizes, the range helps hobbyists tune acceleration and top speed to match track conditions.

Is the XRAY 365721 suitable for heavy use?

The 7075 T6 base and hard coat make it durable for regular use, though all pinions should be inspected periodically for wear.

Can I run this on different track surfaces?

Yes, the pinion is suitable for a variety of surfaces; ensure proper mesh and clean the gear after dusty or gritty sessions.

How do I check for correct mesh with this pinion?

Use a small strip of paper or a feeler method to set the mesh, then rotate the drivetrain to confirm smooth motion without binding.
