Race Series Camshaft Kit - 538 Series - Chain Drive - M8

Highlights

• Kit includes Reaper camshaft, Racer Series full travel hydraulic lifters with 0.200" total travel, gasket/o-ring kit that allows installation of Feuling heavy-duty HP+ 0.0165" wall one-piece pushrods or factory one-piece pushrods, ARP cam/crank fasteners and cam instal kit.
• Made in the USA.
• Due to the unstable nature of 4-valve engine design with one rocker arm activating two valve springs, Feuling recommends running one-piece pushrods over quick-install adjustable pushrods to maintain maximum cam/valve lift and reduce valvetrain harmonics and associated hydraulic lifter issues.
• Feuling fastener kit is recommended to help prevent cylinder head cracking; kit replaces the rocker shaft bolts with studs and nuts to help reduce the stress of the rocker shaft standoffs.
• Race Series lifters have a slower bleed down rate to handle steep ramped cam and heavy valvesprings, designed to increase engine RPM before valve float.
• Screamin' Eagle cylinder heads have high lift valve springs but will need to be verified.
• Not for '23-'24 models with 121" VVT motors.
• High lift valve springs are required on stock Gen 1 cylinder heads.
• RPM Range: 2350-5975.
• Overlap: 38.
