ARP Standard High-Performance Connecting Rod Bolts Chevy V6 2.8L 60°

ARP's High-Performance Rod Bolts are substantially better than the stock OEM and most aftermarket bolts, used in a variety of applications from rebuilt stock motors to highly modified powerplants in circle track, marine and drag racing engines – including those with superchargers and/or nitrous oxide injection systems. Rod bolts are unquestionably the most important fasteners in any engine, as they are the key to the entire rotating assembly. Rod bolts support the primary tension loads caused by each rotation of the crankshaft, ARP's rod bolts are able to exert a clamping force greater than the load imposed upon the tension. ARP's high-performance versions of replacement rod bolts come in 2 options; standard and wave-lock. Also available in Pro Series.

Standard High-Performance Rod Bolts: Premium grade 8740 alloy chrome moly steel that is heat-treated to provide a tensile strength in the 200,000 psi range. Cycle testing shows to be nearly five times more reliable than stock bolts.

Wave-Lock High-Performance Bolts: All the same features of the standard high-performance rod bolts but includes Wave-Loc design that features symmetrical waves and has an effective interference range of .001" to .005" for proper cap alignment. Wave-Loc technology provides a snug, smooth fit.

• Wave-Loc 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
• Superior material grain flow
• Galling and scoring of the rod is virtually eliminated
