Description
Feuling Reaper Camshaft for Harley Davidson Twin Cam
High performance camshafts by Feuling for Twin Cam engines. Available in different configurations to suit your performance needs.
Features:
- Produces 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
- Wide lobe separations produce wide power bands
- Optimized cam timing provides easy starting without the need for mechanical devices or compression releases
- Dyno proven and track tested
- Feuling camshaft installation kits recommended
- Camshaft Set is 2 camshafts
- See cam specific features below
525 Camshaft
- Great bolt-in camshaft upgrade for stock 88” and 96” engines also performs very well in 103” strokers and will respond well to increased compression and cylinder head work
- Designed to increase torque band width and increase fuel economy
- Produces strong low- and mid-range power with linear horsepower and torque curve
- Can be used with factory valve springs, pushrods and lifters
- Increases throttle response and eases starting
- Strongest from 1750-5500 rpm
543 Camshaft
- Excellent bolt-in camshaft for stock to mild 96” and 103” engines and works well in 88” and 95” engines
- The ‘Freeway Flyer’, great camshafts for those who want more top end power than the 525 cams without sacrificing low end torque
- Extremely smooth cam lobe layout maintains quiet valve train and produces the smoothest cruise power band available
- Cam is easy starting, increases throttle response and fuel mileage. Responds well to increased compression ratio, performance exhaust and a high-flow air cleaner
- Performance high lift valve springs are required on 99-04 engines and performance pushrods and lifters are recommended but not required
- Strongest from 1900-6000 rpm
574 Camshaft
- Wicked power band for modified engines and an excellent bolt-in for stock 96”, 103” and 110” engines, a great all-around camshaft with solid low end performance and mind-blowing mid and top end power
- Responds well to modified cylinder heads, increased compression ratio, performance exhaust and intake systems
- Extremely smooth cam lobe design creates a smooth and quiet valve train
- Performance valve springs required on 99-04 engines and performance pushrods and lifters recommended
- Strongest from 2100-6000 rpm
594 Camshaft
- Fierce performing camshaft for an array of engine sizes, for large displacement 103”, 110” and 124” engines looking for a superior torque band with excellent horsepower gains in heavy bikes (2200-6250 rpm). As well as for smaller high-revving displacement 95” style engines in lighter bikes looking to twist the throttle and tap into some horsepower (2500-6800 rpm)
- Large displacements respond well to increased compression ratio and smaller displacements will require it
- 594 cams require high-performance valve springs, pushrods, lifters, carburetor and or throttle body work, performance exhaust, intake and clutch.
630 Camshaft
- Vicious power gains, wide streetable power band from high-lift-profile camshaft for high-performance engines with highly modified cylinder heads and compression ratio
- Carburetor and/or throttle body work required along with a performance exhaust and intake system
- Maintains low end performance with eye-blurring mid and top end power
- High-performance valve springs, pushrods and lifters required
- Strongest from 2500-9000 rpm
General product notes:
Note: Gear drive camshafts come without inner & outer drive gears. Gears must be purchased separately. Installation is a simple press-on installation. If you have gears from your current Andrews or S&S gear drive cam, these can be re-used or a new S&S set purchased. S&S Cam Gear Kit available here.
Note: 594 & 630 high lift cams require adjustable pushrods. 525, 543 and 574 cams are compatible with stock pushrods.
Note: When converting from hydraulic chain tensioners on 06-17 Dyna, 07-17 Softail and 07-16 Touring to gear drive cams, block-off plates are required for the oil holes. Block off kit available here.
Note: Chain drive cams for 99-06 Twin Cam are for use with stock 00-06 Twin Cam splined outer drive gears, for installation on 99 Twin Cam motors you must purchase a splined outer drive sprocket separately, S&S recommends using Andrews Splined Outer Cam Driven Gear 34T.

Timing and duration measured at zero lash and .053" tappet lift off base circle. To avoid coil bind, allow min. .030" more free valve travel than the max. valve lift that is mentioned. To achieve adequate valve spring clearance, several higher lift top collars are available which require no machining.
