Bottom End

• 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...

• 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...

• Power band for modified engines and an excellent bolt-in for stock 96", 103" and 110" engines • Responds well to modified cylinder heads increased compression ratio, performance exhaust and intake systems • Extremely smooth cam-lobe design creates a...
