S&S Cycle 2017+ M8 Models Valve Spring Kit - .605in

This S&S Cycle valve spring kit gives you the components needed to upgrade the valve springs on your 2017 and newer Harley-Davidson M8 engine. You get the springs themselves, top collars, keepers, and bottom collars with seals, all in one package. This kit is designed to work well with camshafts that have lift up to .605 inches, making it a solid option for those looking to improve their engine's performance.

The kit features high-performance conical single wire springs, which are well-built for reliable operation. Made in the USA, these springs are a direct replacement for your stock components and are intended for M8 models from 2017 onwards. This upgrade is a good choice for riders who want a bit more out of their engine, especially when paired with a mild performance camshaft.
