The 3Racing SAK-40B universal shaft roller stabilises the driveline on Sakura Zero vehicles to deliver truer shaft alignment and steadier handling under load. It is a practical tweak for racers and club drivers who want consistency.
By limiting side-to-side shaft movement the roller helps reduce slop in driveline inputs, which can sharpen throttle and steering response and extend the life of linked components.
Designed for routine serviceability, the SAK-40B offers a rugged support point that is easy to inspect and replace if needed, making it suitable for regular track days.
