Duramax CP3K 2001-2016 Cylinder Heads 2001-2007 Duramax 6.6L LBZ / LLY / LB7 fittings and bracketsDuramax CP3K 2001 2016 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. Warranty 12 Months Parts Note
