Get Your Upper A-Arm Bolts While They Got 'Em GM #461854

Very true. Know what you're doing if you sub a metric bolt for an SAE and vice-versa. For example, a 10.9 metric same relative size bolt in SAE Grade 8, the 10.9 is slightly less tensile strength. Not by a lot, however. They do a lot of KPa ratings with metric so you usually have to do a lot of conversion. OR.....you can do like me and just search and mostly find the right bolts via the GM part number. 🙂

I'm guilty of changing several of the 10.9 bolts for Grade 8 bolts on my frame but certain ones stayed metric either by they type of bolt GM used or it was easier to keep it metric cause of how it attaches.
