ARP GENERAL TORQUE RECOMMENDATIONS

Listed below are the general torque recommendations for bulk 5-packs and engine/accessory
fasteners. Recommended torque is equal to 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. Al-
ways use ARP Ultra-Torque® and follow the instructions below to ensure the correct preload is
created.
Apply ARP Ultra-Torque® to fastener threads and the underhead of the bolt or underside of the nut. Install
fastener hand tight. Use torque wrench to install fastener to the torque value from the chart below.
NOTE 1: The torque values represented here are intended to be for general information only, not
for specific installations.
NOTE 2: On specific installations, when the supplied instructions deviate from the torque values
listed here, always follow the specific instructions packaged with each kit.
