288160 Chain drive cam shaft set TW60A/.560"

These Andrews TW60A chain drive camshafts are designed for high-performance 1999 to 2006 Twin Cam models, excluding the 2006 Dyna. Sold as a set, these cams feature a .560-inch valve lift and are ideal for well-prepped 95 to 103 cubic inch engines with a compression ratio between 10.2 and 10.5. When combined with head work and modified exhaust, you can expect a power band ranging from 2700 to over 6500 RPM, putting 100-plus horsepower within reach. They are compatible with stock hydraulic lifters, though high-lift springs are required. Owners of 1999 models will need to purchase a splined 2000-2006 style driven gear separately. For these higher lift applications, we recommend upgrading to a gear drive or converting to the later hydraulic chain tensioners to ensure long-term reliability.
