Product Overview

MILWAUKEE EIGHT CAM

521 CAM
•521 grind chain crive cam, 518 Intake lift, 521 Exhaust lift, high lift valve springs required, performance pushrods and lifters recommended. RPM 2,250-6,250.
•Aggressive pulling power with a nasty sound, the REAPER 521 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.

465 CAM
•465 grind cam, 445 Intake lift, 465 Exhaust lift, direct bolt in replacement chain drive, can be used with factory valve springs, pushrods and lifters. RPM 1,850-5,950.
•This direct bolt in replacement for Milwaukee Eight engines can be used with stock valve springs, pushrods, lifters and exhaust.
•Use of performance valve-springs is not required but may result in a quieter, smoother running valve-train.

508 Cam
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
2500 - 6250 rpm range


Twin Cam:

525 CAMS
•Designed to increase torque band width and increase fuel economy
•Great bolt-in camshaft upgrade for stock 88" and 96" engines also performs very well in 103" motors, will also respond well to increased compression and cylinder head work
•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
•1750-5500 rpm power range

543 CAMS
•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
•Excellent bolt-in camshaft for stock to mild 96" and 103" engines and works well in 88" and 95" engines
•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 valve springs are required on 99-04 engines and performance pushrods and lifters are recommended but not required
•1,900 - 6,000 rpm power range

574 CAMS
•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
•2100-6500 rpm power range

594 CAMS
•Fierce performing camshaft for an array of engine sizes, large displacement 103", 110" and 124" engines looking for a superior torque band with excellent horsepower gains in heavy bikes (2,200 - 6,250 rpm)
•Smaller high-revving displacement 95" style engines in lighter bikes looking to twist the throttle and tap into some
horsepower (2,500 - 6,800 rpm)
•Large displacements respond well to increased compression ratio and smaller displacements will require it
NOTE: 594 cams require high-performance valve springs, pushrods, lifters, carburetor and or throttle body work, performance exhaust, intake and clutch.

630 CAMS
•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
•2500-6900+ rpm power range

Evo Cams:

518 CAMS
•Will respond well with performance exhaust and air cleaner
•1650 - 5500 rpm power range
•Direct bolt in replacement for EVO engines
•Can be used with stock valve springs, pushrods and lifters
•Will also respond well with increased compression and cylinder head work

543 CAM
•Performance lifters recommended but not required
•Increased compression, cylinder head work and performance exhaust recommended but not required; increased compression is required for bottom end performance
•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 are required.
•Requires performance valve springs.
•2200 - 5950 rpm power range.

594 CAM
•Performance exhaust and intake/air cleaner upgrades also required.
•Requires performance valve springs, performance lifters, adjustable pushrods, increased compression and cylinder head work.
•2500 - 6400 rpm power range.
