IF YOU HAVE PIRATE JACK ROTORS...READ THIS! DANGEROUS! Today, I planned on installing new drilled slotted front rotors for my 1971 Charger that I purchased from Pirate Jack. They are part number 5314RX and 5314LX and fit 1962-1972 Mopar B&E Body. I did not want to use the preinstalled bearing races (also called cups) that come with the rotors, as overseas manufactures will use the cheapest available. I removed the inner race to install an SKF bearing race (part number BR6) and realized the diameter is different. The correct race OD is 59.1mm and Pirate Jack's are 59.95mm. I added the second photo below which details the correct diameter taken from RockAuto. Ok, this seems like nothing but the correct race is completely loose and will not stay secure in the rotor. Also the correct ID of the race should be 48.2mm, but Pirate Jack's is 49.2mm which means the bearing is riding incorrectly in the race. This could EASILY lead to dangerous failure! As I have two new inner bearings (left and right) I took the photo below showing the bearing seated in Pirate Jack's race (left) and the correct race (right). You would not likely notice this unless you removed the preinstalled race. I will be contacting Pirate Jack.
