Why Upgrade Flywheel Bolts?
Factory bolts can:
-
Stretch under high load
-
Lose clamping force over time
-
Fail under aggressive launches
-
Compromise drivetrain safety
ARP hardware offers:
-
Higher tensile strength
-
Improved fatigue resistance
-
Precision-machined threads
-
Consistent torque retention
On a turbo 4G63, stronger hardware is cheap insurance.
