Arrowmax AM-664090: Tuned for Smoothness

The Arrowmax AM-664090 Super Differential Gear 64P 90T is engineered to reduce gearing noise while remaining robust for repeated use. Its reduced mass is aimed at improving rotational response without compromising component life during track sessions or practice.

Noise Reduction and Fitment Notes

The refined tooth profile gives quieter meshing compared to standard gears and improves consistency under load. Arrowmax AM-664090 is compatible with a broad range of electric touring and pan car designs and is available in sizes from 86T to 110T in 64dp and 68T to 88T in 48dp for flexible gearing choices.

Practical Benefits for Tuners

Installing the Arrowmax AM-664090 can reduce drivetrain buzz and offer a more predictable feel through corners. That balance of light construction and strength makes it a sensible upgrade for tuners focused on drivetrain refinement.

Do I need to alter gear mesh when fitting this unit?

Yes, recheck pinion to spur mesh after installation. A correct mesh prevents premature wear and preserves the quieter operation this gear is designed for.

Will this gear change my final drive ratio?

Only if you select a different tooth count or dp size. The Arrowmax AM-664090 itself is offered in multiple sizes so you can choose the exact ratio needed for your setup.

How often should I inspect the differential gear?

Regular checks every few outings are recommended, looking for abnormal wear, chipped teeth, or excess play. Prompt attention keeps performance consistent and avoids larger repairs.
