When should I replace the inner cam needle bearing?

It's highly recommended to replace the inner cam needle bearing whenever you are installing a new camshaft. This ensures that the new cam has a fresh, strong bearing surface to operate within, preventing premature wear.

What does 'M8 engine' refer to?

The 'M8 engine' refers to Harley-Davidson's Milwaukee-Eight engine family, which was introduced in 2017. This bearing is specifically designed for those models.

Does this bearing come with any installation hardware?

This product includes the inner cam needle bearing itself. Installation hardware, such as seals or retaining clips, is not explicitly listed as included and may need to be sourced separately if required for your specific camshaft installation.
