Hughes main stud girdle - yes or no

They really aren't all that expensive, and for me, it was worth it for the extra insurance. I have a 4" crank, so I'd recommend it for a 4.125 crank. With that crank, you'll probably have to do some clearancing on the girdle because mine comes pretty close. Might want to call Hughes and ask if it will work. Also works like a scraper to get excess oil off the crank.
