Setup Precision with 3RACING 3RAC-PG6435

The 3RACING 3RAC-PG6435 pinion is produced from 7075 aluminium and finished with a hard coat to support repeatable gear engagement in competitive environments. Its 64 pitch, 35 tooth geometry allows fine incremental changes to final drive ratios that matter in race tuning.

Engineering Notes

7075 aluminium provides high yield strength while keeping inertia low to maintain rapid throttle response. The hard coating adds wear resistance to the surface without significantly changing tooth profile, preserving tuning consistency.

Tuning and Application

Use this pinion when precise ratio control is required. Small tooth swaps at 64 pitch yield measurable effects on acceleration and top speed; pair with a matching 64 pitch spur and verify mesh under race conditions.

What spur gear specification should be used with this pinion?

Match the pinion to a 64 pitch spur gear to ensure correct tooth contact. Verify tooth counts and clearance before final assembly.

Is a break in or run in required for best results?

Perform controlled low load runs to seat gear faces, then inspect mesh and temperatures. Progressive load increases help stabilise contact patterns for consistent lap times.

Any setup tips to protect the pinion under race loads?

Maintain correct mesh, use dust protection where possible, and avoid abrasive contaminants. Inspect for nicks and replace if profile degradation is observed to protect the spur and drivetrain.

Why choose 7075 aluminium for a racing pinion?

7075 aluminium offers a high strength to weight ratio ideal for reducing rotational mass while retaining dimensional stability under load, which is important for consistent gear engagement in competition.
