This is information that you can never find when you need it so here is a table for the ARP Head Studs, Main Studs, and Rod Bolts Torque Specifcations and Stretch Specs.
Listed here are the general torque recommendations for most ARP fasteners. Recommended torque is equal 75% of the fastener’s yield strength. Simply read down to the correct fastener size, then across to find the torque value for your application. Always lubricate the fasteners prior to applying torque to ensure accurate readings.
NOTE: The torque values represented here are intended to be for general information only, not for specific installations. On specific installations, where supplied instructions deviate from the torque values listed here, always follow the specific instructions packaged with each kit.
