Description
Engine fastener failure under boost or high RPM operation isn’t just an inconvenience—it’s catastrophic. The Feuling External Fastener Bolt Kit 3061 delivers the fastener integrity that separates reliable builds from roadside failures, using ARP-manufactured 8740 chrome moly bolts engineered specifically for Twin Cam engines that demand uncompromising quality.
These aren’t generic hardware store bolts. Each fastener features precision rolled threads, a wide underhead flange for even load distribution, and a tensile strength rating of 170,000 psi—exceeding both OEM and Grade 8 specifications. Paired with included moly assembly lubricant, this kit ensures consistent torque loading and eliminates the galling that compromises seal integrity and invites leaks.
