ARP High Performance Rod Bolt Kit 9mm Toyota MR2 4AGE 85-89
Because factory connecting rods (or aftermarket versions of OEM rods) are used in a variety of applications from rebuilt stock motors to modified powerplants used in circle track, marine and drag racing engines - including those with superchargers and/ or nitrous oxide injection systems - ARP offers replacement rod bolts that are substantially better than the stock OEM and most aftermarket 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.
