Needle Bearing for piston wrist pin

Grubee Inc


Only SkyHawk engines have the best quality 10 roller piston pin needle bearings as standard issue.  

Competitor's engines have the cheap 9 roller bearings.   Advantage: SkyHawk

Both 9 and 10 roller bearings are interchangeable except for the quality difference.  The higher priced 10 roller sold here-in is a premium choice.
