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.

ARP developed the Wave-Loc shank design that features symmetrical waves with an effective interference range of 0.001 Inch to 0.005 Inch for proper cap alignment. The waves replace the knurl on standard replacement bolts - eliminating the stress risers that are created when cutting into the shank - which create potential failure points. The tensile and fatigue strengths are the same as our regular high performance rod bolts.

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
