Description
Your engine’s reliability depends on fasteners that can handle extreme clamping loads and thermal cycling without loosening or failing. ARP’s Pro Series Flywheel Bolt Kit delivers the strength and durability required in high-performance and racing applications, where stock bolts simply won’t cut it. This chromoly construction resists fatigue and vibration while maintaining consistent preload—critical for maintaining flywheel concentricity and preventing catastrophic drivetrain failure.
