Torque the rods
Rod bolt threads and underside of the nut should be lubricated with ARP Moly Assembly lube. Do not use oil or loctite.
Cap should be seated on rod by aligning cap by hand and tapping in place. Alternatively tighten nuts to avoid cocking
of the cap. ARP recommends that the rod bolts be tightened and lessened four additional times prior to assembly.
