1999-2013 Chevrolet Silverado 1500 2500 4.8 5.3 6.0 Oil Pump Assy 12556436 OEM.

Fresh pull off from my 125k mile 2004 silverado 4.8 that i put turbos on and swapped into my offroad truck. I upgraded to a high volume pump. There is nothing wrong with this oil pump and the motor ran smooth with proper oil pressure. This is ready to go. Never ran dry. Was removed today 5/17 and was wiped with a rag. Ready to be installed immediately.

Not rusty inside. Still has oil coating.

Will be shipped within 24 hours of purchase.
