Competitive tune focused 48 pitch pinion

The 3Racing 48P 28T is specified for racers refining gear ratios and drivetrain reliability. Machined from 7075 aluminium and hard coated, this pinion balances weight, stiffness and surface hardness to support consistent tooth contact under repeated load cycles. It is suitable for fine tuning gear ratios in 48 pitch systems and pairs well with high quality spurs for predictable lap time performance.

top stuff indeed very fast postage price $$$ so good as trust me sakura zero all pink all hop ups lol.....this site rocks i saved so much throught these guys you will also

How should I approach mesh tuning with the 3Racing 48P 28T?

Start with a small paper shim method to set minimal backlash, then run a few short laps and recheck mesh and set screw torque to maintain consistent engagement.

What benefits does the hard coat provide during race weekends?

The hard coat improves surface durability so the pinion retains tooth profile longer between service intervals, which helps maintain lap time consistency.

Any compatibility notes for drivetrain upgrades?

Use it with a matching 48 pitch spur and verify motor timing and gear ratio choices to avoid excessive torque spikes that could overload the pinion or spur.
