Fleece Performance 01-13 GM Duramax 6.6L Duramax CP3K (LBZ/LMM Based)

The Fleece Performance CP3K is a modified Duramax LBZ CP3 designed to eliminate the factory fuel flow restriction that begins at 3,000 RPM. If you have a stock CP3 pump you are losing fuel flow and rail pressure after 3000 RPM, which correlates to lost horsepower when you need it most. This cost effective upgrade will allow you to maintain desired fuel rail pressure through your entire RPM range.This Part Fits: Year Make Model Submodel 2006-2010 Chevrolet Express 2500 Base 2006-2010 Chevrolet Express 3500 Base 2001-2005 Chevrolet Silverado 2500 HD Base 2001-2006 Chevrolet Silverado 2500 HD LS 2001-2010 Chevrolet Silverado 2500 HD LT 2007-2010 Chevrolet Silverado 2500 HD LTZ 2004,2006-2010 Chevrolet Silverado 2500 HD WT 2001-2005 Chevrolet Silverado 3500 Base 2001-2006 Chevrolet Silverado 3500 LS 2001-2006 Chevrolet Silverado 3500 LT 2004,2006 Chevrolet Silverado 3500 WT 2007-2010 Chevrolet Silverado 3500 HD LT 2007-2010 Chevrolet Silverado 3500 HD LTZ 2007-2010 Chevrolet Silverado 3500 HD WT 2006-2010 GMC Savana 2500 Base 2006-2010 GMC Savana 3500 Base 2002-2005 GMC Sierra 2500 HD Base 2001-2002,2006 GMC Sierra 2500 HD SL 2001-2010 GMC Sierra 2500 HD SLE 2001-2010 GMC Sierra 2500 HD SLT 2003-2010 GMC Sierra 2500 HD WT 2002-2005 GMC Sierra 3500 Base 2001-2002,2006 GMC Sierra 3500 SL 2001-2006 GMC Sierra 3500 SLE 2001-2006 GMC Sierra 3500 SLT 2004-2006 GMC Sierra 3500 WT 2007-2010 GMC Sierra 3500 HD SLE 2007-2010 GMC Sierra 3500 HD SLT 2007-2010 GMC Sierra 3500 HD WT
