Owners of the Cero series can use the 3RACING SAK-C136 5.2mm ball cap as a straightforward spare or small upgrade. It locates in the front upper wishbone to help preserve suspension geometry and reduce unwanted movement.
Engineered for the Cero front upper arm, the cap gives a firm seating for the ball stud and helps keep steering precise. The 5.2mm dimension enables quick swaps during service sessions without complicated adjustments.
Press the cap in squarely and ensure mating surfaces are clear of grit. After fitting, check steering throw and suspension travel to confirm correct installation before running.
