Description
Stock valve cover fasteners are prone to stripping, corrosion, and vibration-induced loosening—especially under high-heat engine bay conditions. ARP’s chromoly stud kit replaces weak OEM hardware with precision-engineered fasteners that maintain clamp load and resist thermal cycling. Whether you’re building a forced-induction engine or just demand reliability, these studs deliver the holding power your valve cover needs.
The 12-point nut design provides superior grip and easier installation compared to traditional 6-point hardware. Each stud is individually manufactured to ARP’s exacting tolerances, ensuring consistent performance across your entire engine.
