Precision pulley upgrade for Sakura Advance

The 3Racing SAK-A512 is a 40T aluminum pulley made for the Sakura Advance lineup. It is engineered to tidy up drivetrain power delivery and provide a durable replacement part for regular track use.

Lightweight strength and consistent fit

Machined from aluminium for a balance of stiffness and low weight, the SAK-A512 reduces friction points and helps maintain reliable gear engagement. The part is produced to tight tolerances to ensure repeatable installation and long service life under racing loads.

Track-focused performance gains

As an upgrade component, this pulley supports smoother drivetrain rotation and can contribute to steadier lap times by improving power transfer. It is suitable for hobbyists and club racers who tune their Sakura Advance for competition.

Can I fit the SAK-A512 to a stock Sakura Advance?

Yes. The 3Racing SAK-A512 is designed for the Sakura Advance series and installs in the same pulley location as the original part. Check fit and alignment during installation.

Does aluminium require special maintenance?

Aluminium is durable but benefit from routine inspection. Keep the pulley free of grit, verify set screws or fasteners are secure, and confirm smooth rotation after running sessions.

Will this change gear mesh or gearing ratios?

The SAK-A512 keeps the same tooth count at 40T, so it does not alter gear ratio. Its benefit is in reduced friction and improved mechanical efficiency rather than changing final drive ratio.
