Feuling Parts Cam - 508 Series - Reaper - Chain Drive - M8 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" 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 USA • Cam specs measured in the engine on the lifter @ 0.050 using a 1.61 rocker arm ratio • 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 - Harley-Davidson Electra Glide Ultra Classic EFI FLHTCUI (2017, 2018, 2019); Harley-Davidson Electra Glide Ultra Limited FLHTK (2019, 2020, 2024, 2017, 2021, 2022, 2023, 2018); Harley-Davidson Road King EFI FLHR (2019, 2022, 2020, 2021, 2017, 2018); Harley-Davidson Road Glide Ultra FLTRU (2017, 2018, 2019); Harley-Davidson CVO Electra Glide Ultra Limited FLHTKSE (2020, 2019, 2017, 2018, 2021); Harley-Davidson Softail Breakout 114 FXBRS (2019, 2018, 2020); Harley-Davidson Softail Deluxe FLDE (2019, 2020, 2018); Harley-Davidson Softail Fat Boy 114 FLFBS (2018, 2020, 2021, 2019, 2023, 2024, 2022); Harley-Davidson Softail Heritage Classic 114 FLHCS (2018, 2022, 2023, 2020, 2019, 2021, 2024); Harley-Davidson Freewheeler FLRT (2017, 2018, 2022, 2023, 2021, 2019, 2020, 2024); Harley-Davidson CVO Road Glide Custom FLTRXSE (2021, 2019, 2020, 2022, 2023, 2018, 2024); Harley-Davidson Tri Glide Ultra Classic FLHTCUTG (2021, 2019, 2023, 2020, 2017, 2018, 2024, 2022); Harley-Davidson CVO Tri Glide FLHTCUTGSE (2022, 2021, 2020); Harley-Davidson Electra Glide Police FLHTPI (2022, 2017, 2018, 2019, 2020, 2021, 2023, 2024); Harley-Davidson CVO Street Glide FLHXSE (2022, 2023, 2024, 2018, 2019, 2017, 2020, 2021); Harley-Davidson CVO Road Glide Limited (2023, 2022); Harley-Davidson Street Glide ST FLHXST (2023, 2022); Harley-Davidson Electra Glide Highway King FLHFB (2023); Harley-Davidson Road Glide Limited FLTRK (2023, 2020, 2021, 2022, 2024); Harley-Davidson Electra Glide Standard EFI FLHTI (2019, 2020, 2022, 2021); Harley-Davidson Softail Low Rider FXLR (2019, 2020, 2018); Harley-Davidson Softail Slim FLSL (2019, 2018, 2021, 2020); Harley-Davidson Softail Low Rider S FXLRS (2020, 2021, 2024, 2022, 2023); Harley-Davidson Softail Street Bob FXBB (2021, 2018, 2020, 2024, 2019, 2022, 2023); Harley-Davidson Softail Sport Glide FLSB (2021, 2020, 2018, 2019); Harley-Davidson Road King Special FLHRXS (2021, 2018, 2019, 2020, 2024, 2023, 2022, 2017); Harley-Davidson Street Glide Special FLHXS (2023, 2017, 2022, 2021, 2018, 2019, 2020); Harley-Davidson Road King Police FLHP (2019, 2020, 2017, 2024, 2018, 2021, 2022, 2023); Harley-Davidson Softail Standard FXST (2024, 2022, 2020, 2023, 2021); Harley-Davidson Softail Low Rider ST FXLRST (2024, 2022, 2023); Harley-Davidson Electra Glide Ultra Limited Low FLHTKL (2019, 2018, 2017); Harley-Davidson Street Glide EFI FLHX (2020, 2024, 2018, 2019, 2017, 2022, 2023, 2021); Harley-Davidson Road Glide Custom FLTRX (2018, 2021, 2023, 2019, 2020, 2024, 2017, 2022); Harley-Davidson Softail Heritage Classic FLHC (2020, 2018, 2019, 2021); Harley-Davidson Road Glide Special FLTRXS (2021, 2017, 2022, 2020, 2018, 2019, 2023); Harley-Davidson Hydra-Glide Revival (2024); Harley-Davidson Softail Fat Bob 114 FXFBS (2022, 2019, 2023, 2020, 2021, 2018); Harley-Davidson Softail Fat Bob FXFB (2018, 2019); Harley-Davidson Road Glide Police FLTRXP (2024); Harley-Davidson Softail Low Rider El Diablo FXRST (2022); Harley-Davidson Softail Breakout FXBR (2019, 2023, 2018, 2024); Harley-Davidson Softail Fat Boy FLFB (2018, 2019); Harley-Davidson Road Glide ST FLTRXST (2023, 2022); Harley-Davidson CVO Road Glide ST FLTRXSTSE (2024); Harley-Davidson Electra Glide Revival (2021); Harley-Davidson FXDR 114 (2019, 2020)
