Engine bearings

[Raptor]

Not us, not anymore. We have found two bearing manufacturers that destroy the clevites for quality and are similar in price. I no longer will use clevites because I don't like the fact that I have had to spend a half hour on "adjusting" them to get them to satisfactory condition before using them. Each set I was getting for a while there was getting progressively worse.

The ACL's are a much nicer bearing for finish and they seem to maintain tighter tolerances during manufacturing. I have another manufacturer's bearing set being sent now as well so I can verify what I have read and seen with them. The material is not the typical tri-metal, the tolerances are claimed to be tighter than anyones and they are the top supplier of bearings to top fuel applications. They are said to work equally well in long duration high RPM use as well as the DD's. I will have examples of all of them at the shop soon so anyone interested can compare. These are the bearings we will be running in Curtis's 2.14 if they are even close to what they sound. I will tell the manufacturers name after I see a few more responses, I am doing a bit of a blind test to see if anyone suggests them without me saying what they are.
