Gear Ratio Options for 3Racing SAK-65J Pulley

The 3Racing SAK-65J pulley set for Sakura Zero offers both 39 and 40 tooth gears so you can adjust final drive characteristics accurately. These pulleys are intended to keep consistent mesh and reliable power transfer, making them suitable for regular racing or club track use. A practical replacement for maintaining setup choices and preserving drivetrain performance over time.

Can I run the 40T on long straights?

Running 40T will nudge top speed up slightly, which benefits long straights, but check your pinion and motor RPM to avoid pushing the motor beyond safe limits.

Are these pulleys robust enough for frequent events?

They are produced for reliable service, but inspect teeth and spline fit regularly and replace if wear starts to affect gear mesh to prevent drivetrain damage.
