ARP has introduced Pro Series rod bolt kits for Ford, Chevrolet/GM and Dodge/Cummins diesel engines. Forged from proprietary ARP2000 material, the premium grade fasteners are nominally rated at 220,000 psi tensile strength and are substantially stronger than the OEM fasteners. Given the increased loads placed on rod bolts—typically the weakest link in an engine—by engine modifications, ARP’s new rod bolts are important reliability “insurance” for owners of performance-enhanced diesel trucks.
In addition to being made from superior material, ARP rod bolts are thread rolled after heat treating, which adds significantly to their fatigue strength. All manufacturing operations, including forging, heat-treating, machining and finishing, are done entirely in-house at ARP’s California facilities to stringent AS9100 and ISO-9001 quality control standards.
ARP rod bolts are available for the Ford 6.0L/6.4L Powerstroke (p/n 250-6301). Chevrolet/GMC 6.6L Duramax (p/n 230-6301), Dodge/Cummins 5.9L (p/n 247-6303) and 1999- 2001 Ford 7.3L Powerstroke (p/n 250-6302).
