Fleece Performance LML CP3 Conversion Kits

Why convert your LML's fuel system from a CP4 to a CP3? Since its introduction, the CP4 has proven to be less reliable and less capable than the CP3 used in previous Duramax platforms—resulting in costly repairs for owners when a CP4 fails.

They provide OEM fit-and-finish features, like Fleece's exclusive molded hoses for the fuel feed and return, high flow CP3 fuel fittings, and their valley feed line to support aftermarket lift pump applications. Fleece Performance LML CP3 conversion kits are offered with or without pump and the pump kits come in two different style pumps—a Bosch CP3 injection pump or Bosch CP3 pump with heavy-duty 10mm cam. Choose the kit that is right for you. All kits include: * CP3 to rail high pressure fuel line * High-flow CP3 feed and return fuel fittings * Preformed fuel feed and return fuel hoses * CP3 mounting adapter * Dosing injector distribution block, feed and return lines * FCA extension harness * Low pressure fuel feed line * Hardware kit

King XP-Series Rod Bearings

King XP-Series rod bearings feature advanced metallurgical and geometric technologies that meet extreme performance loads. They were developed for all performance applications that use forged steel aftermarket crankshafts and produce high loads for extended periods. King focuses on one product—bearings—and nothing else. Their innovative race-only Xtreme Performance Max Black Tri-Metal rod bearings have a 24 percent stronger overlay and 17 percent more fatigue strength by using a micro process called SecureBond. Built with enhanced tri-metal, King XP-Series rod bearings layer copper-lead construction with a nickel plate barrier and a lead/tin/copper Babbitt overlay over a steel backing in an adhesion process that provides superior stability and durability. King's advanced control measures hit a bull's-eye, maintaining wall thickness tolerances far tighter than their competitors—at an amazing +/- .0001 in.! XP-Series rod bearings are narrowed on the crank cheek side with increased crush height for improved bearing-to-bore contact, heat transfer, and reduced spin potential in high-rpm applications.
