The 3Racing Sakura Zero S Heavy Duty Gear Differential Set (SAK-S01/HD) is developed with competitive tuning in mind. It provides a more robust drivetrain platform that helps teams and solo racers maintain consistent lap-to-lap performance.
Component reinforcement and attention to gear engagement reduce deformation and wear during sustained high-load manoeuvres. This supports predictable differential behaviour when adjusting diff preload and oil setups for race conditions.
Designed to match Sakura Zero S mounting and clearances, the SAK-S01/HD enables straightforward installation while allowing racers to focus on setup changes such as diff oil weight and preload to fine tune traction characteristics.
