No tool box or workshop is complete without a selection of assembly lube. As the name suggests, these oils and greases help precision-machined engine and transmission parts slide together without damage during assembly. Some are also formulated to stick around to help lubricate parts during the crucial initial start-up and break-in period, and most will dissolve or wash away harmlessly during normal operation.

Summit also carries other compounds you’ll need for engine and mechanical projects, including anti-seize and thread locking compounds, as well as engine oil and gear oil.

ARP Ultra Torque Fastener Assembly Lubricant

Because of frictional inconsistencies with oil, moly, and other lubricants, it takes multiple cycles of torquing the bolt, loosening it, and tightening it again to obtain the required preload or stretch. Typically, when a fastener is first tightened, friction is at its highest point and the preload value or stretch is low. As the fastener is cycled numerous times the friction decreases and the preload increases. This phenomenon is called "preload scatter." With ARP Ultra Torque assembly lubricant, a fastener need only be torqued once to get within 5 percent of ideal preload, and it remains consistent through all subsequent cycles (from race-prep machining through final assembly). Moreover, given the inconsistencies of ordinary lubes, it's 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. Order the tube or container size needed for your applications.
