Jeep Wrangler Main Bearing - Engine

Used in my Jeep 4.0 engine rebuild along with my ground original crankshaft (ground 0.010" undersize by my machine shop). The bearings fit perfectly and all oil clearances measured 0.002" with plastigage. I was concerned when the copper was exposed on the thrust bearing, so I contacted Sealed Power tech support. Someone quickly responded and advised that was normal. Great tech support!! The crankshaft thrust clearance measured within spec. And oil pressure is great after rebuild. I also used Sealed Power connecting rod bearings, pistons, and moly rings. Product quality seems great. I'd use them again. Rebuild runs perfect.
