Industrial XP1285105 XP Series CP3 | 2006-2010 GM Silverado/Sierra 2500HD/3500HD 6.6L Duramax

More fuel output than any CP3 on the market. What makes these pumps unique are the oversized plungers in combination with DLC coating and higher lift crankshafts. Standard plungers measure 7.5mm, XP plungers are 8.5mm. The XP Series pumps will be offered with our 12mm crank shaft. The new plungers and tappets are all hardened and DLC coated to ensure reliability, longevity and reduce sticking.  We test all of our pumps not only on state of the art test equipment, but also on the highest level competition vehicles. With our engineering on the XP Series CP3 pumps you can produce more fuel output with less pumps.
