ARP Rod Bolts
Choose From Three ARP Replacement Rod Bolts
Because factory connecting rods (or aftermarket versions of OEM rods) are used in a variety of applications from rebuilt stock engines to modified powerplants used in circle track, marine, and drag racing engines- including those with superchargers and/or nitrous injection systems- ARP offers replacement rod bolts in three different models. All of them are substantially better than stock OEM or most aftermarket bolts.
Good: Standard High Performance Bolts
A premium grade 8740 alloy chrome-moly steel is used to manufacture ARP high performance connecting rod bolts. This material is heat treated to provide a tensile strength in the 200,000 psi range, which is substantially stronger than OEM bolts. Cycle testing shows ARP high performance rod bolts are nearly 5 times more reliable than stock bolts.
Better: Wave-Loc® High Performance Rod Bolts
The same heat treated 8740 chrome-moly steel used to make these rod bolts as ARP's standard high performance rod bolts. The big difference is the shank design, with ARP's exclusive (and patented) Wave-Loc technology providing substantial benefits. Because there are fairly wide tolerances with factory bolt holes, the bolt must be able to fit snugly and a knurl is applied. Unfortunatly, these knurls cut deep into the bolt material leaving sharp edges and enormous "stress risers" that promote failure. Thats why ARP developed the Wave-Loc design that features symetrical waves, and has an effective interference range of .0005" to .007 for proper cap alignment.
Best: Pro Series Wave-Loc® Bolts
For the most severe applications, in conjunction with aftermarker "I" beam rods, ARP has developed the "Pro" series Wave-Loc bolts. These ultra heavy-duty rod bolts are made from a special material designated ARP2000. It has approximately 200% of the fatigue life of 8740 chrome-moly steel and has a tensile strength of abot 220,000 psi, and is capable of more than 12,000 lbs. clamping force.
