S&S Cycle 2017+ M8 Models Anti-Rotation Tappet Cuffs

S&S Cycle has been a well-known name in performance motorcycle parts for a long time, and these anti-rotation tappet cuffs are a solid example of their focus on engine components. If you're working on the engine of a 2017 or newer Harley-Davidson M8 model, these cuffs are designed to keep your tappets perfectly aligned, especially when you're pushing the engine hard at high RPMs or with high-lift cams.

These cuffs capture the tappets without interfering with their vertical movement, which is crucial for proper valve train function. They're made from billet aluminum with a hard anodized black coating, making them strong and resistant to distortion, even under high stress. This is a great upgrade to consider when you're changing out tappets or doing a cam swap, as it directly addresses tappet stability. Just remember to check the clearance between the tappet and the cuff, as there can be variances between different cam and tappet manufacturers.

This part fits a range of Harley-Davidson models, including the Road King, Street Glide, and Fat Boy, among others from 2017 onwards. It's a straightforward way to improve the reliability and performance of your M8 engine.
