Bottom End

• Wide power band for modified engines • Bolt in for stock 103" and 110" engines • Works well with 95", 106", 107" and 114" big bore engines • RPM range 2000-6800 • Smooth lobe design creates a very smooth valvetrain motion • Responds to modified...

• Stock replacement roller chain drive sprocket • Made in the USA • Will work on early '99-'06 engines when upgrading to the hydraulic cam chain tensioner using the roller chain. - Harley-Davidson CVO Fat Bob FXDFSE2 (2010); Harley-Davidson Fat Bob FXDF...

• Stock deck height • Large volume sump • Machined, close-fitting oil scraper (stock is as cast) • A solid foundation for building a big-bore engine • Made in the USA • Includes Manufacturers Statement of Origin (MSO) document • Can be paired with a S&S...

• Start any engine regardless of displacement or compression ratio with a stock starter • Save your starter and battery; tested for 10,000 starts without running battery down • Allow for easy start by initially reducing crank compression, but once the...

• Stage 1 is designed for low end torque • Adds a 5%-10% power gain • Designed and dyno proven in the USA • Manufactured by utilizing state of the art valvetrain software • CNC machined from 8620 billet, case-hardened steel for an exact fit and lobe...

• Revs up fast and pulls hard in engines with big bore cylinders, modified cylinder heads, intake,compression and exhaust • The Reaper® 538 grind will shine in 124” and larger cubic inch engines with added compression ratio • The stock throttle body...

• Requires performance valve springs • Performance lifters recommended but not required • Will work with factory pushrods on engines with factory stack up • If deck height, cylinders or rocker boxes have been modified from stock then adjustable pushrods...

• Race series • RPM range 3100-6650 • Aggressive camshaft requiring high lift and higher load valve springs, performance pushrods and lifters. • Requires large bore size, ported cylinder heads, ported intake manifold, high flow valves and large throttle...

• Produces solid bottom-end performance and substantial gains above 2800 RPM compared to the stock cams • Direct bolt-in replacement for M-Eight engines; can be used with stock valve springs, pushrods, lifters and exhaust • Will respond well when used...

• Produces a wide powerband that increases torque and horsepower throughout the entire rpm range • Direct bolt-in replacement for M8 engines; can be used with stock valve springs, pushrods, lifters and exhaust • Will respond well when used with slip-on...

• 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...

• Produce a wide powerband in stock engines • Split lift camshaft produces a solid powerband with top fuel sound • Can be used with stock pushrods and valve springs • Fueling recommends new camshafts with new lifters (not required) - Harley-Davidson...
