S&S Cycle 570G Camshaft Kit - 33-5178

Upgrade your Harley-Davidson's performance with the S&S Cycle 570G Camshaft Kit. This gear drive camshaft kit is engineered to deliver increased valve timing accuracy and superior performance. Experience the difference in power and responsiveness that S&S Cycle provides.

Description

The S&S Cycle 570G Camshaft Kit is specifically designed for 88" to 103" CID engines with compression ratios between 9:1 and 10:1. This kit provides the strongest performance gains in the 3200-3700 RPM range, making it ideal for riders seeking enhanced mid-range power. By utilizing a gear drive system, the kit eliminates timing chain lash and replaces loosely fitted stock chain drives, resulting in more precise valve timing. The innovative design reverses the rear cam's rotation, which creates additional operating clearance between cam lobes, allowing for higher cam lifts. S&S Cycle's commitment to quality ensures that you receive a product that is built to last and perform. Note that material must be removed from the inner surface of the stock gear cover to ensure proper installation.
