The 3Racing SAK-40M supplies 42mm steel universal shafts that replace weaker stock pieces and deliver firmer, more predictable drivetrain behaviour. These shafts suit drivers who want fewer breakages and steadier lap times.
Crafted from durable steel, the universals resist wear and bending under repeated load. The 42mm length matches Sakura Zero specifications for a direct fit and consistent drivetrain geometry.
On tarmac or broomed carpet, the 3Racing SAK-40M helps maintain traction response by reducing drivetrain play. This upgrade reduces component fatigue and helps other parts last longer.
