lower a-arm ubolt fasteners - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I got a new set of lower a arm ubolts for the front suspension from LMC but the nuts aren't lock nuts. Should I find lock washers, a better nut, or just torque and it will be fine?

I would get the lock nuts myself. Rockwell calls them type 'C' (crimp) 9/16''-18

Iirc, they are a grade 8 flanged locknut. I bought mine at the hardware store.
