Product Details
When you're looking to replace a camshaft in your S&S emissions certified engine, this 520 Camshaft from S&S Cycle is a solid option. It's designed as a short duration emissions cam, meaning it has very little valve overlap. This design helps reduce the amount of unburned hydrocarbons released, which is important for meeting emissions standards.
This camshaft is intended for use in engines with a 1000-4500 rpm range, covering displacements from 80 to 96 cubic inches. Because it's a high-lift camshaft, you'll need to make sure you have high-lift valve springs installed. It's also crucial to perform normal clearance checks during installation to ensure everything is set up correctly. This part is built for a range of Harley-Davidson Big Twin models from 1984 to 1999, including popular bikes like the Electra Glide Classic, Heritage Softail, and Dyna Super Glide.
