• 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
• Produces strong low and mid-range power with linear horsepower and torque curve
• Increases throttle response and eases starting
• RPM range 1750-5500
• Overlap is 9°
• Can be used with factory valve springs, pushrods and lifters.

543 Grind Cams

• Offers more 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 mid 96" and 103" engines and works well in 88" and 96" 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
• 1900-6000 RPM power range
• Performance valve springs are required on '99-'04 engines and performance pushrods and lifters are recommended but not required.

574 Grind Cams

• Performance pushrods, lifters and clutch are recommended.

594 Grind 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 (2200-6250)
• 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 or throttle body work, performance exhaust, intake and clutch

630 Grind Cams

• Carburetor and or throttle body work required along with a performance exhaust and intake system
