The 3RACING SAK-C147D swing main shaft is a service replacement targeted at drivers who require repeatable pivot action from the Cero rear assembly. It helps provide consistent swing geometry run to run, which is essential when tuning handling balance.
Manufactured to match the 3RACING Cero swing mounting pattern, the SAK-C147D allows quick swaps during setup sessions. Confirm correct seating and alignment as small deviations can affect toe and camber behaviour under load.
For reliable performance, install the 3RACING SAK-C147D into clean housings and check bearings for endplay. Tighten fasteners in a cross sequence and verify free movement through the full travel. Regular inspection after track sessions helps maintain consistent handling.
