Sealed Power Engine Piston P/N:2744PN
Bring the bottom end of your 6.6L V8 back to spec with the Sealed Power Engine Piston 2783PNR. This application-specific piston drops in as a direct-fit replacement for the listed V8-6.6L applications, including the 2006-2010 Chevrolet Silverado 2500 HD, 2006-2010 GMC Sierra 2500 HD, 2006-2010 Chevrolet Express 2500/3500, 2006-2010 GMC Savana 2500/3500, and 2007-2010 Silverado/Sierra 3500 HD — see the Buyer's Guide tab for the full list.
Designed to help restore engine performance, the piston converts combustion pressure into the reciprocating motion that drives the crankshaft, while its rings seal the combustion chamber and control oil. If worn or damaged pistons are the cause of low compression, excessive blow-by, oil consumption, or piston slap, this replaces them. Country of origin: United States. Manufacturer part number 2783PNR.
