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 the OEM bolts. Cycle testing shows ARP High Performance rod bolts to be nearly five times more reliable than stock bolts.

BETTER: WAVE-LOC HIGH PERFORMANCE BOLTS
The same heat-treated 8740 chrome moly steel is used to make these rod bolts as ARP's standard High Performance rod bolts. The big difference is in the shank design, with ARP's exclusive (and patented) Wave-Loc technology providing substantial benefits. Because there are fairly wide tolerances in factory bolt holes, the bolt must be able to fit snugly and a knurl is applied. Unfortunately, these knurls cut deep into the bolt material, leaving sharp edges and enormous "stress risers" that promote failure. That's why ARP developed the Wave-Loc design that features symmetrical waves and has an effective interference range of .001" to .005" for proper cap alignment.

BEST: "PRO" SERIES WAVE-LOC BOLTS
For the most severe applications, in conjunction with aftermarket 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% the fatigue life of 8740 chrome moly steel and has a tensile strength of 220,000 psi, and is capable of more than 12,000 lbs. clamping force.
  • Wave-Loc surface contacts the rod and cap for optimum alignment and reduction of fluctuating stress - which strengthens the rod itself!
  • Provides snug fit for all OEM connecting rods (interference range of .001" to .005"), despite wide range of factory rod bolt hole tolerances.
  • Available for most applications.
  • Superior material grain flow because of patented Wave-Loc surface design as compared to knurled bolts that have sharp edges and "built-in" stress risers.
  • Galling and scoring of the rod is virtually eliminated because there is only smooth contact and absolutely no "digging."
