Setup and Ratio Tuning for 3Racing SAK-65J Pulley

The 3Racing SAK-65J gear differential pulley fits Sakura Zero models and provides two tooth counts, 39T and 40T, so you can adjust drive characteristics precisely. Use the 39 tooth for crisper acceleration and the 40 tooth for a slightly taller ratio; both options are built to give reliable power transfer and consistent mesh. This replacement is aimed at hobbyists who want a durable upgrade or a direct fit spare for race day maintenance.

Which Sakura Zero variants will accept this pulley?

The pulley is manufactured to suit the Sakura Zero differential system; check your model parts list or service manual to confirm fitment before fitting it to your car.

Should I choose 39T or 40T for corner exits?

Pick 39T for snappier throttle response and faster spool up on corner exit, while 40T will smooth the mid range and improve top speed; test both with your motor and gearing to find the best balance.
