ARP Ultra Torque lube (.5oz)

ARP Ultra Torque assembly lubricant makes hardware assembly much easier!

Frictional inconsistencies in oil, molybdenum disulfide, and other common lubricants require multiple cycles of bolt torquing, loosening, and retightening to obtain the required preload or stretch. Typically, friction is at its highest point and the preload value or stretch is low when a fastener is first tightened. As the fastener torque is cycled several times the friction decreases and the preload increases. This phenomenon is called "preload scatter".

With this product, a fastener need only be torqued once to achieve within 5% of ideal preload. Then, it remains consistent throughout all subsequent cycles (from race-prep machining to final assembly). Inferior assembly lubricants lead to torque inconsistencies. It is quite possible for adjacent head bolts or studs to have vastly different preloads. This scatter causes bore distortion, hampers piston ring seal, and leads to poor head gasket sealing. Pro engine builders choose ARP Ultra Torque lubricant for a reason!
