3Racing SAK-F19A 39T Ball Differential and 39T Solid Axle Gear Race Set  [SAK-F19A]

Race oriented 39T gear set for Sakura FF tuning

The 3Racing Sakura FF 39T Ball Differential Gear and 39T Solid Axle Gear are engineered for setup flexibility and consistent drivetrain feedback. These parts support precise diff preload tuning and predictable axle engagement under racing load conditions.

39T tooth profile for predictable torque transfer

The 39-tooth geometry aids in maintaining consistent torque transfer and minimises abrupt load shifts. The ball differential permits fine adjustments to slip characteristics, enabling setup technicians to influence turn-in, mid-corner balance and exit traction.

Fitment, installation and setup considerations

Designed to fit Sakura FF chassis mounting points, the gears install with standard tools. When fitting in a race environment, check bearing play, confirm pinion/spur mesh, and use controlled diff fill or shims to achieve repeatable performance lap after lap.
