The 3RACING SAK-C113 is an M6 bowed E-ring engineered for reliable shaft retention in the Cero platform. Its bowed profile supplies a spring preload that keeps pins and shafts securely seated under lateral loads and vibration common in competitive use.
Install with proper tools to avoid deforming the ring; ensure the shaft groove is clean and free from burrs for optimal engagement. For tuning work, verify axial play after fitting to confirm correct seating.
Intended as a maintenance and upgrade part, the SAK-C113 performs well in high duty cycles and frequent assembly changes typical of race teams. Regular inspection after impacts and during rebuilds will maintain drivetrain reliability.
