I torque my Cragar lug nuts to 75 ft lbs. Never had them loosen up..."yet". Back in the day (70's) when Cragar washers were captive to the nut on some of their wheels, they were a better grade lug nut and I could torque them higher than that. But these "new" repops will crush and I had one or two nuts actually split at the threads if I try to torque them any higher. Called Cragar the first time it happened and they told me to not go higher than 75 lbs or I'll risk damage to the lug nut or washer. They said "it's only a 7/16 stud, no need to go any higher" Seems light to me, but hey what do I know. Chinese crap.
