Shearing the lugbolts ???

[420nitro]

Has anybody ever heard or experianced shearing the lug-bolts/studs off there axles on a 9/10 sec car. I have a 4 lug w/31 spline moser axles and going to 5 lug. The question is should I be leary on driving this car until I convert to a 5-lug?

I've never shear any studs off, but back when I was only running 4 stud axles (Strange 31 spline) I bend all 4 studs, two different times. Certain people claimed it was because I had loose lug nuts. Trust me, they were never loose. I always torque them to 100 ft-lbs with a torque wrench and check them before going to the track.

I switched to Moser 5 stud axles. And now I'm running the lug nuts that have a flat washer and a straight shank that goes all the way through the Weld rims. My car is over a second quicker now (high 9's) and I have had zero problems. I don't know if it was fixed because of the fifth stud, or because of the shank style nuts (I used to only run the acorn factory style nuts with factory 10 hole rims).

Hope this helps.

Thanks, I just talked to moser's tech line and they stated that I should at least up-grade to the 5/8 studs and then upgrade to 33 spline 5-lug axles and spool for the low 9 sec attempt.

I've kicked that idea around as well. Right now I just have 1/2"-20 x 3" long studs, 31-spline, Detroit locker. A lot of folks say the spools aren't too bad for street driving.
