ARP's Pro Series Rod Bolts are substantially better than the stock OEM and are among the best aftermarket bolts which money can buy, 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.
