The 3Racing SAK-D536 ball cap is built to tighten the connection between servo horn and linkage on the Sakura D5S, yielding clearer steering feedback for setup changes and track adjustments. It helps translate steering inputs with minimal lost motion.
In competitive settings, repeatability matters. The SAK-D536 holds alignment at the joint so steering geometry remains stable when refining toe, ackermann or servo endpoints, aiding precise setup iteration.
Designed to integrate with the Sakura D5S servo horn arrangement, this ball cap ensures predictable ball stud positioning and a secure mechanical link. It is a practical part for teams and drivers focused on reliable steering behaviour.
