Exedy is the largest OEM manufacturer of clutches in Japan, and has built clutches for TRD and Ogura in Japan. Exedy now has inventory in the USA, and we are a stocking supplier of their clutch line.

For high-powered applications, EXEDY offers twin and triple Multi-Plate Clutches. These are designed for hot street action as well as drag, road and rally racing.

The twin plate clutches are rated 600 ft lbs at the flywheel. The triple plate clutches are rated for 800 ft lbs (for drag race applications). Twins come as with both spring damper discs and solid discs. Triples are all solid discs.

All of Exedy's multi-plate clutches come with a lightweight, chrome moly steel flywheel, and the famous purple anodized forged aluminum clutch cover. All have T5001 cerametallic friction materials for extreme heat resistance.

The twin disk clutch is perfect for 750 HP or less cars, and with a sprung set-up offers a truly lightweight pedal feel for excellent drivability and performance. This is a complete set-up with lightweight flywheel. Outstanding value and performance.

The EXEDY Street / Race Twin Plate Clutch is designed for high torque capacity with "reasonable" steetability. The friction facing material is cerametallic to bundle the abuse of highly modified engines. Again, with all cerametallic clutch systems, some chatter should be expected on low rpm startups. Featuring a single spring damper for both discs, this design has strap lift and drive for both the pressure plate and the intermediate plate. A patented system evenly lifts both the main pressure plate and the intermediate plate providing a "clean" release for steetability. The EXEDY Street / Race Twin Plate Clutch also includes a lightweight billet chrome moly steel flywheel for maximum performance.

Q&A:

What is clutch inertia and why is it important?

Answer:

Heavy clutches have such a large inertia (like a very heavy wheel turning) that it makes shifting more difficult, and clutch longevity difficult. Inertia is the tendency of the combined clutch/flywheel to maintain motion even when not been driven by engine torque. For example, with most twin disk (and many heavy single disk clutch assemblies) even when you relax on rpm to make a smooth shift during normal or even high speed driving, the combined inertia from a heavy clutch makes for a notchy and difficult shifting feel. The affects low speed driving significantly and makes the car feel sluggish off the line. The lower weight Exedy clutches help minimize this reaction to negative inertia.

Q:

What about heat in multi-plate clutch designs, isn't that an issue for higher hp cars?

A:

Great question. Most multi-plate disk clutches do not offer a center track between the clutch plates for the exhaust of the heat generated via friction with the clutch disks are doing their duty. This causes faster disk wear and a very sticky feel of the clutch, often referred to as on-off feel on engagement/disengagement. This can also contribute to the lack of speed shifting ability in overly heated multi-plate clutches used when drag racing or trying to shift very quickly. The Exedy design utilizes a center port for the exhaust of heat which minimizes these issues.
