So as u all know my truck is bagged,well long story short my upper shock mount bolt on the rear seems like the shoulder is too long because with the nut tightened all the way u can still see the shoulder and the shock makes alot of noise. My question is if I buy a grade 8 or higher bolt to replace the 12x1.75mm bolt does it HAVE to have a shoulder at all or can it be fully threaded? I Understand the shock itself sits in the shoulder but what other reason is for the shoulder? Maybe so u dont over tighten? or will the bolt back off if it doesnt have a shoulder to stop? thanks guys.
