S&S Cycle 91-16 Sportster/94-02 Buell Models Camshaft

This is the S&S Cycle 555 camshaft, designed for 1991 through 2019 Harley-Davidson Sportster models and 1994 through 2002 Buell models. If you're looking to get more out of your 89 to 100 cubic inch engine, especially in the 3500 to 6500 rpm range, this camshaft can make a notable difference. It's built to work well with engines that have a compression ratio between 9.5:1 and 11.5:1, and it performs best when paired with ported stock heads or S&S cylinder heads.

The S&S 555 cam is a popular choice for riders who want improved performance without going to an extreme build. It's engineered to deliver a strong powerband in the mid-to-upper rpm range, which translates to better acceleration and a more responsive feel when you're riding. When installing this camshaft, you'll need to account for a few things. It requires the use of adjustable pushrods, spring spacing, or high-lift valve springs. As with any camshaft installation, it's important to perform normal clearance checks to ensure everything is set up correctly and safely.

This camshaft is a significant upgrade for your Sportster or Buell engine, offering a noticeable boost in performance where many riders want it most. Remember that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for detailed guidance on fitment and setup.
