Kit includes 565141 cam support plate and 565144 TC3 oil pump. Must convert to 06-17 style hydraulic chain tensioners; otherwise a direct replacement for Twin Cam stock style oil pump and cam support plate. Compatible with chain & gear driven camshafts. Offers all round improvement over the stock components. Both are CNC machined forged aluminum for strength and precision. The camshaft support plate offers an adjustable oil pressure regulator; passage plugs are removable for service; a rebuildable bronze pinion shaft bushing and for 07-17 models rebuildable bronze cam bushings. The oil pump comes with three sets of gerotors for consistent pressure and increased oil scavenging for a reliable oil return. More forgiving for cam run-out. Offers screens and magnetic traps to catch debris before it does damage to the scavenge rotor. Note: When using chain driven cams 06-17 style hydraulic chain tensioners are required.
