Fine Gear Adjustment for 3Racing SAK-65J

The 3Racing SAK-65J pulley set for Sakura Zero swaps between 39 and 40 tooth options to let you fine tune the final drive for different track conditions. Both tooth counts are intended to run smoothly under load and to hold mesh under repeated use, so you can alter acceleration or top speed without compromising reliability. Suited to tuners who like to test setups on mixed surfaces and tweak their drivetrain for grip and response.

Is this compatible with aftermarket diff housings?

This pulley is sized for the Sakura Zero differential; some aftermarket housings may accept it but you should confirm spline and diameter before installing.

How do tooth changes alter driving feel?

Dropping a tooth generally sharpens acceleration and response, while adding a tooth softens acceleration but raises potential top speed; try both to see which suits your motor and track.
