Description
Head studs are the critical foundation of engine reliability under high boost, nitrous, or sustained high-RPM operation—factory bolts simply cannot handle the clamping force demands of a built LS engine. The ARP CA625+ Pro-Series delivers superior clamp load consistency and fatigue resistance compared to OEM hardware, ensuring your cylinder head stays sealed under extreme conditions. If you’re running forced induction or pushing past 500 hp, this upgrade is non-negotiable.
