Your cart is empty.Because of frictional inconsistencies with oil, moly, and other lubricants it takes multiple cycles of torqueing 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 this 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 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.

Right amount to do all my head bolts

This packaged showed up next day and couldn’t have been at a more perfect timing! Thank you guys! Everyone else would have taken multiple days to receive this! It was enough to torque my head studs on a LS3 V8 engine and all 16 rocker are studs with little left over!

Mostly bought this so I could reinstall the head studs in my YXZ after a few modifications. It’s a small packet, but should easily be able to do 2-3 YXZ engines. A little goes a long way with this stuff! Make sure to use gloves when applying, it gets everywhere 😂.

It works I'll tell you that, if you want to get rid of the popping and get a accurate torque spec on cylinder head bolts, please get this. Soaked bolts in oil didn't work for me.

OMG, just buy it. Trust me you’ll love it and will order more.

This stuff is a must when installing nuts on cylinder head studs.
