Included in this kit is a packet of ARP Ultra Torque Fastener Assembly Lubricant. It is specially formulated to eliminate “preload scatter: and will enable you to achieve within 5% of the desired preload on the “first pull”. Please refer to the enclosed installation instructions for determining the correct fastener tightening requirements. 
All fasteners are manufactured entirely at ARP’s California plant. From initial forging through heat-treating, centerless grinding, thread rolling, machining to final finishing, all work is done totally in-house. Rigorous quality control measures are also used to ensure that only the best possible parts are delivered to you.
