FEULING OIL PUMP CORP. Rockerbox Bolt Kit 3046

Factory fasteners are a compromise—they're designed to meet minimum specifications, not maximum performance. The Feuling Rockerbox Bolt Kit 3046 upgrades your Twin Cam engine with premium 8740 chrome moly bolts that deliver 170,000 psi tensile strength, outperforming both OEM and Grade 8 fasteners. When you're building or rebuilding a serious engine, precision fasteners prevent costly failures and ensure consistent, reliable torque loading across critical connection points.

Manufactured by ARP to Feuling's exact specifications, these bolts feature precision-rolled threads and a wide underhead flange that distributes load evenly—eliminating stress concentration and preventing the galling and leaks that plague standard hardware. Each kit comes with moly assembly lubricant for proper installation, so you have everything needed to secure your engine with confidence.
