The 3Racing Sakura Zero Gear Differential Spacer Set, model SAK-65B, is intended for tuners seeking consistent spacer stacks to achieve predictable gear mesh on the Sakura Zero chassis. The set helps maintain repeatable assembly during setup changes and rebuilds.
Using consistent spacer thickness reduces variability in gear engagement and can improve drivetrain predictability under varying loads. This aids in dialing-in setups for different track conditions and helps reduce maintenance variables between runs.
