FEULING OIL PUMP CORP. Fastener Kit - External Engine - 12-Point - XL 3120

If you're rebuilding or upgrading your external engine assembly, fastener quality directly impacts reliability and longevity under extreme loads. OEM fasteners can't match the tensile strength and precision thread engagement of purpose-built racing hardware—especially when you're running higher boost or aggressive cam profiles. This Feuling kit eliminates guesswork with ARP-manufactured fasteners engineered to exact specifications, delivering consistent clamping force and preventing the costly failures that come from stripped threads or failed seals.

Built tough for professional-grade applications and backed by decades of racing credibility, these fasteners give you the confidence that your engine assembly will hold together when it matters most.
