For 99-06 Twin Cam (except 06 Dyna Glide). REAPER® CAMS FOR TWIN CAM. Produce more power and torque in the riding RPM range increasing throttle response, acceleration and fuel mileage. Wide lobe separations produce wide power bands. Smooth camshaft lobe ramps are easier on valve-train components and eliminate excessive valve-train noise and wear. Dyno proven and track tested. Feuling® camshaft installation kits recommended. Optimized camp timing provides easy starting without the need for mechanical devices or compression releases. Made in the U.S.A.. NOTE: Installation will require the separate purchase of a S&S or Andrews 4-gear gear drive kit.. 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" 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. 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. Extremely smooth cam lobe layout maintains quiet valve train and produces the smoothest cruise power band available. 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. 1900 - 6000 rpm power range. 574 CAMS. - Part Number - 0925-0425
