Brake kits: 4 piston or One ??

I have met the Ram man, and he talked me threw everything, parts kit showed up and even after the sale I had no problems, but I did call to check if I could talk to someone if I had any kind of problem, His first site was hacked by someone !! I can't and will not say who and what site did it.. I had zero problems with the man.. We all have our own opinion and I am happy to see them here, never have dealt with Doctor Diff, so I have no Idea :thumbsup:
