Great info. I wonder if it coincides with the black painted housings. One more thing probably missing from my '11 Brembo GT.

Just wanted to update this thread for all Track Pack/BOSS/13-14GT500 owners.

Here are some pictures of the normal 8.8 pinion bearing for the normal 11-14 5.0 and 11-12 GT500 Mustangs on the left, and the noticeably larger bearing for the TP/Boss/13-14GT500 on the right.

Oldstv, I looked at the bearing and it is indeed a KOYO USA made piece, the part number I found stamped on it was: ST4190
