Tech Tip: ARP recommends using the ARP Ultra Torque Fastener Assembly Lubricant as opposed to motor oil or other low-quality lubricants. This is due to higher friction on the studs as well as inconsistencies in the clamping force of the fasteners when insufficient lubricants are used.

Please Note: While following the manufacturer’s recommended torque sequence, tighten the nuts to the ARP recommended torque specifications using ARP Ultra Torque Fastener Assembly Lubricant.
