Race Series® chain drive cam kit - RS 538 CD M8

Kit includes Reaper® camshaft, full-lift 0.200" Racer Series hydraulic lifters, gasket/O-ring set allowing installation of Feuling HP+ 0.0165" wall single pushrods or original pushrods, ARP® cam/crank bolts and cam installation kit.
Manufactured in the USA
Due to the unstable nature of the 4-valve engine design with a rocker arm actuating two valve springs, Feuling recommends using single-piece pushrods rather than quick-install adjustable pushrods to maintain maximum cam/valve lift and reduce valvetrain vibrations and associated hydraulic lifter issues.
Feuling fixing kit recommended to prevent cylinder head cracks; replaces swingarm pivot bolts with studs and nuts to reduce stress on the pivot supports.
Race Series tappets have a slower release rate to support cams with steep ramps and reinforced valve springs, allowing higher RPM before valve float.
Not suitable for '23-'24 models with 121" VVT engines.
RPM range: 2350-5975.
Overlap: 38.
