Rod Bolt Stretch & Torque Specs
ARP's Pro Series 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. For the most severe applications, ARP has developed the Pro Series Wave-Loc rod bolts. These ultra heavy-duty rod bolts are made from a special material - ARP2000, which has approximately 200% the fatigue life of 8740 chrome moly steel. The tensile strength of the pro series is 220,000 psi and is capable of more than 12,000 lbs. clamping force. Also featured is Wave-Loc design, which contacts the rod and cap for optimum alignment and reduction of fluctuating stress. Wave-Loc provides a snug fit with superior grain flow, vitrtually eliminating galling or scoring of the rod.

WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
WARNING: The wires of these products contain chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Wash hands after handling.
