Cobb Tuner Crank, Pauter rods so I hope the bearings are fine as that's a lot of cash down the drain is the bearings fail.
Were these the ACL Duraglides or RACE series?

I bought these bearing about 2 years ago, from a shop that is on this form. I check the clearance back then, check good, installed on crank and did not like the feel, so I removed them and reinstalled the Subaru bearings. Two years of hard abuse, pulled the motor, bearing still looked good, had crank checked and re-polished. Checked clearance on ACL bearings, installed and still did not like the way they felt, but decided to run them (1/2 Subaru 1/2 ACL). 2 dyno sessions and one trip, started to see some debris in oil. Pulled engine and inspected. ACL bearing were coming apart. Subaru’s look fine.
ACL coated bearings
When I bought them, I talked on the phone about these bearings; they said they were better than Subaru, NO WAY!!! At this time I did not know if ACL made a race series?
Now looking at the bearing and ACL web site the part number does not look like the race series part number.
060C03
8296
STD
The race series number is 4B8296H
If I was not the type of person that checks everything all the time, I would have lost a bearing. Every oil change I inspect the oil filter, Canton.
