OEM connecting rods are used in a variety of applications from rebuilt stock motors to modified powerplants used in circle track, marine and drag racing engines. ARP offers replacement rod bolts in three different models. All of them are substantially better than the stock OEM and most aftermarket 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 high strength ARP2000. This material doubles the fatigue life of 8740 chrome moly steel and has a tensile strength of 220,000 psi, which means it can deliver more than 12,000 lbs. of clamping force.

Features and Benefits:

• 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 Inch to .005 Inch), despite wide range of factory rod bolt hole tolerances
• 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 no digging
• Threads are rolled, not cut
