Feuling M8 Chain Drive 508 Reaper Camshaft (1349)

Produce more power and torque in the riding RPM range, improving throttle response, acceleration and fuel mileage Smooth camshaft lobe ramps are easier on valvetrain components and eliminate excessive valvetrain noise and wear Dyno proven and track tested The Grim Reaper aggressive pulling power with a nasty sound This camshaft revs up faster than the 521 grind, sounds nastier and pulls harder, but is more difficult to tune The Reaper 508 grind will shine in 114 inch and larger cubic inch engines with added compression ratio Ported cylinder heads are not required, but will complement the cam and add even more pulling power throughout the range The stock throttle body produces an excellent powerband and use of a high flow throttle body will increase peak power numbers A high-flow exhaust system and air cleaner is highly recommended for optimal performance High-lift valve springs are required Heavy-duty pushrods are highly recommended 2250 - 5900 rpm range Made in the U.S.A. Due to the unstable nature of this 4-valve engine design with one rocker arm activating two valve springs, Feuling highly 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 Fitment 2018-2019 Harley-Davidson Breakout FXBR 107 2018-2020 Harley-Davidson Breakout FXBRS 114 2018-2020 Harley-Davidson Deluxe FLDE 107 2019-2020 Harley-Davidson Electra Glide Standard FLHT 2017-2019 Harley-Davidson Electra Glide Ultra Classic FLHTCU 2018-2019 Harley-Davidson Fat Bob FXFB 107 2018-2020 Harley-Davidson Fat Bob FXFBS 114 2018-2019 Harley-Davidson Fat Boy FLFB 107 2018-2020 Harley-Davidson Fat Boy FLFBS 114 2017-2020 Harley-Davidson Freewheeler FLRT 2019-2020 Harley-Davidson FXDR FXDRS 114 2018-2020 Harley-Davidson Heritage Classic FLHC 107 2018-2020 Harley-Davidson Heritage Classic FLHCS 114 2018-2020 Harley-Davidson Low Rider FXLR 107 2020 Harley-Davidson Low Rider S FXLRS 114 2017-2020 Harley-Davidson Road Glide FLTRX 2020 Harley-Davidson Road Glide Limited FLTRK 2017-2020 Harley-Davidson Road Glide Special FLTRXS 2017-2019 Harley-Davidson Road Glide Ultra FLTRU 2017-2020 Harley-Davidson Road King FLHR 2017-2020 Harley-Davidson Road King Special FLHRXS 2018-2020 Harley-Davidson Softail Slim FLSL 107 2018-2020 Harley-Davidson Sport Glide FLSB 107 2018-2020 Harley-Davidson Street Bob FXBB 107 2017-2020 Harley-Davidson Street Glide FLHX 2017-2020 Harley-Davidson Street Glide Special FLHXS 2017-2020 Harley-Davidson Tri Glide Ultra FLHTCUTG 2017-2020 Harley-Davidson Ultra Limited FLHTK 2017-2019 Harley-Davidson Ultra Limited Low FLHTKL
