Cam Bearing Kit, Twin Cam Models (OEM/NOS)
We know very little about this kit, and most that we see do not have an identifiable part number, as a kit. So we suspect this "kit" is actually a "SUB" group of components for a larger Cam update kit. The only bearing we have identified is the 8990A. We presume most builders will readily identify the other needle bearings in the group.
