Known Issues4 issues
critical
Crank Hub Slip Moderate (~20%)
The press-fit crank hub can slip under high load, losing timing synchronization and causing catastrophic engine damage. More common on tuned cars but can affect stock. Aftermarket pinned solutions are strongly recommended for tracked or tuned cars.
Typical Mileage
Mileage independent – load dependent
