Product Details
Twin Power is known for making reliable parts for Harley-Davidson motorcycles. This cam chain tensioner outer assembly is built to replace the original on your Big Twin engine from 1999 through 2006, excluding the 2006 Dyna models. It's designed to fit just like the stock part, making installation straightforward when you're working on your engine's timing components.
What sets this tensioner apart is the Twin Power shoe material. This compound is specifically chosen for its ability to last longer than OEM parts, reduce friction, and handle higher temperatures. This means you get a more durable tensioner that helps keep your cam chain running smoothly and quietly for more miles. It's a solid option for anyone rebuilding or maintaining the top end of their motorcycle.
This part replaces Harley-Davidson part number 39954-99A and is sold individually. Make sure to check your specific model's fitment to ensure it's the right tensioner for your bike.
