ARP reinforced connecting rod bolts
The big end bolt is the hardest working item in a bottom end: every revolution it carries the inertia load of the piston and rod assembly, and if it fails the block goes with it. Twelve part numbers…The big end bolt is the hardest working item in a bottom end: every revolution it carries the inertia load of the piston and rod assembly, and if it fails the block goes with it. Twelve part numbers are active on this page. Ten are forged ARP bolts sold individually and identified not by a catalogue code but by their size, diameter and length: that is how engine builders work when rebuilding a rod to measure or replacing a bolt that has stretched. The last two references are the assembly consumables, Ultra-Torque lubricant and the Teflon thread sealer. The maker requires the bolt to be renewed at every strip: it works within its plastic range.
