525 CAMS - A real workhorse, designed to increase torque band width and increase fuel economy. Great bolt in camshaft upgrade for stock 88” & 96" engines also performs very well in 103" strokers. Produces strong low and mid range power with a linear horsepower and torque curve. Can be used with factory valve springs, pushrods and lifters. Increases throttle response and eases starting. Will also respond well to increased compression and cylinder head work. RPM 1,750 – 5,500
543 CAMS - The 'Freeway Flyer', a great camshaft for those who want more top end power than our 525 cam 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" & 95" engines. This 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. RPM 1,900 - 6,000
574 CAMS - Wicked power band for modified engines and an excellent bolt in for stock 96”, 103” & 110” engines. This is a great all around camshaft with solid low end performance and mind blowing mid and top end power. Extremely smooth cam lobe design creates a very smooth valve-train motion. Responds very well to modified cylinder heads, increased compression ratio, performance exhaust and intake systems. Performance valve springs are required on ’99-’04 engines and performance pushrods, lifters and clutch modifications are recommended. RPM 2,100 - 6,500
594 CAMS - Fierce performing camshaft for an array of engines sizes, large displacement 103", 110" & 124" engines looking for a superior torque band with excellent horsepower gains in heavy bikes (RPM 2,200 - 6,250.) Smaller high revving displacement 95" style engines in lighter bikes looking to twist the throttle and tap into some horsepower (RPM 2,500 - 6,800). 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 CAMS - Vicious power gains, wide streetable power band from a 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, lifters and clutch required. RPM 2,500 - 6,900+
