The Hayes "original" flywheel coupling absorbs vibration and shock to provide a steady dampening effect. The one-piece design gives you worry-free installation and ensures that your coupling will be installed properly the first time, every time.

When the L-Series coupling just isn't getting it done. Install our Hayes Jaw Coupling and watch your problems dissolve away. For some OEMs, jaw coupling failures are costly and time consuming. We keep many sizes in stock and have plenty of room in our driveway for those times you need to send a helicopter for a coupling emergency (yes, this really happens sometimes).

Have a pulley or an overhung clutch you need to drive? Look no further. Our Bearing Supported Stub Shafts allow you to side-load the back of an engine, while not allowing any load back to the crankshaft.
Are you out of length but still have some width to work with? Start counting on Hayes for your entire side load needs.

What can we say about our engine housings? Well, they are the best. We start with only the finest aluminum. Put that together with thick wall sections and custom mounts and you have an engine housing that will stand the test of time. Don't forget to specify a Hayes housing when designing your next application! (Available with couplings, as a kit!)
