The 3RACING SAK-C136 5.2mm front upper wishbone ball cap is intended as a dependable service part for competitive Cero setups. It provides a consistent seating interface between the upper arm and the ball stud to maintain predictable handling under load.
Designed to locate precisely in the Cero front upper wishbone, the cap secures the ball joint and minimises lateral movement. The 5.2mm bore ensures repeatable alignment for quick component swaps during race day servicing.
Install the cap with clean mating surfaces and verify the seat depth for correct engagement. Inspect the joint after high stress sessions and replace the cap when wear or deformation appears to retain consistent steering feedback.
