Well two of the mother#%>?>>>!ers broke at the Allen head. See the little cracks. WTF!!! Really bad. Very little pressure while tightening into my 273 rockers. The rockers already had threads chased and were very clean. No issues with originals.
Hoping this is not an ongoing quality issue with these locking nuts. Plus they sent one that was the wrong sized ball end. SMH!!!
Going to call Mancini Racing and see if they will send a new set. I don’t trust the one I got.
What do you guys think?
