Timing Kits

About Timing Kits

A timing kit groups the parts needed to put an engine's valve timing right in one box. This is a small category, and the kits shown are for Harley-Davidson engines: a stock-replacement hydraulic tensioner kit for the M8, and a Twin Cam cam chest with plate kit for standard cams.

Choose by engine family and cam style, and read the contents of the listing, since a kit can combine several parts. Check whether gaskets, seals and hardware are included. If your engine has other cams, a different year or a different tensioner setup, check the details before you order. Pick your machine in the Ride Finder at the top of the page. Timing marks must be lined up exactly as your service manual shows.

Brands here are S&S Cycle, Motion Pro and Feuling Parts. Related categories are Tensioners & Pulleys, Timing Belts & Chains and Sprockets, all within Timing Components & Kits.

FAQs on engine timing kits

What is a cam chest kit?

On a Harley-Davidson Twin Cam, the cam chest is the housing area that holds the camshafts and the parts that drive them. A cam chest kit brings parts for that area together. Check the listing for what is in it.

Will a timing kit for one Harley engine fit another?

No. Kits are made for a particular engine family, such as M8 or Twin Cam, and sometimes a certain cam style or year range. Match the engine and read the fitment notes, or use the Ride Finder at the top of the page.

Do I need new gaskets when I fit a timing kit?

Usually. Opening the cam area disturbs its gaskets and seals, and reusing them risks leaks. Check whether your kit includes them, and follow the service manual for the procedure, since the order of assembly and the tightening values matter.

Is a timing kit a job for a beginner?

It is a job that needs the service manual and the right tools, because wrong timing can damage the engine. If you are unsure about timing marks or torque, have an experienced mechanic do the work.
