EXEDY Corporation, formerly Daikin Manufacturing Company, is the largest independent OEM clutch supplier to the Japanese automotive market. A Japan-based company, EXEDY Clutch supplies clutches to Ford Motor Company and General Motors in the U.S. In addition, EXEDY supplies clutches to all major Japanese auto manufacturers and is Japan’s leading supplier of racing clutches.
Consistent with their tradition of quality, all EXEDY racing and performance clutches are designed, engineered and built as race clutches – not rebuilt from stock clutches. Unlike other performance clutch manufacturers, EXEDY clutches are not made of gray cast iron from rebuilt stock clutches. Instead, EXEDYclutch pressure plates are newly constructed from ductile (nodular) iron for your increased safety in harsh performance environments.
EXEDY is a Tier 1 OEM supplier to all major automotive, and off-highway manufacturers across the globe. This means we work hand in hand to engineer products to exact specifications and requirement as set forth by the manufacturer. We even supply the products sold as “OEM” from your local dealership.
The EXEDY Pro-Kit clutch assembly you will receive is manufactured on the same production line as OEM clutch components! Not many companies can promise you the guaranteed operation and durability that the car manufacturers demand of our product.
Stage 1 Organic
EXEDY Stage 1 Organic Racing Clutches only use premium friction materials that are resistant to slippage and burst. Increased clamp loads give the necessary capacity to handle modified engines. This is the ideal clutch for street and light horsepower track use.
Drivability is similar to the stock clutch. Pedal efforts will be slightly higher because of the higher clamp loads. All of our Stage 1 clutch discs have spring center dampers to reduce drivetrain shock and provide smooth clutch engagement.
Stage 2 Cerametallic
EXEDY cerametallic clutches are designed to handle the abuse of high power modified engines. Our cerametallic friction material can handle much more abuse than stock type disc assemblies without slipping and fading.
All EXEDY Stage 2 cerametallic clutch discs have sprung center dampers to reduce the impact and shock loads transmitted through the drivetrain. We offer two types of cerametallic discs, “thick” and “thin” along with a cushion button disc.
Hyper Single Series
The EXEDY Hyper Single Series clutch is engineered to optimize the performance of cars that are moderately modified, but do not require the clutch capacity of a multi-plate clutch. Similar to our multi-plate clutches, it has a purple anodized, forged aluminum cover. The aluminum cover is stiffer than a stamped cover and therefore allows a higher lever ratio to maintain the pedal efforts at a reasonable level. There is no clamp load deflection as found in a pressed metal type cover. Additionally, the pressure plate features a series of turbine-like, air flow enhancing vanes that keep the clutch cooler under extreme operating conditions to improve wear life.
All Hyper Single clutches come with a chromoly steel flywheel and are normally supplied with a 6-puck cerametallic facing and a spring center damper disc assembly. However, on select vehicles, the new VF (Various Friction) disc may be offered. The chromoly flywheel is lighter than OEM for improved engine response, and a lighter overall assembly. The disc is generally smaller and thinner than the OEM disc making for lower inertia and therefore quicker, easier shifting and less wear and tear on the transmission synchros. The higher clamp load and cerametallic friction facings give approximately twice the holding torque of the OEM clutch and higher than other single disc clutches.
Hyper Multi Series
For high-powered applications, EXEDY offers twin and triple Multi-Plate clutches. These are designed for high power street action as well as drag, road and rally racing. The twin plate clutches are rated for approximately 500 ft/lbs of torque and the triple plates are rated for approximately 800 ft/lbs of torque, both figures at the flywheel. Twins come with both spring damper discs or solid discs depending on application, whereas triples are all solid discs and not recommended for street use.
All EXEDY Hyper Multi-Plate clutches come with a lightweight, chromoly steel flywheel and the famous purple anodized forged aluminum clutch cover. Depending on the application, we have both strap drive and lug drive models. All have T5001 cerametallic friction materials for extreme heat resistance. Surprisingly, even with it’s additional power capability, most multi-plate clutches exhibit light pedal pressure thanks to a half-engaged “zone” provided by the patented clutch “cushion” function.
Hyper Compe Series
The new standard for racing clutches is now available, with the EXEDY Hyper Compe Series. The ultralight metal multi-plate was developed with a focus on those interested in racing of all sorts. This fields-proven performer has posted numerous wins and boasts excellent reliability in a variety of leading categories. Exceptionally fast shifting and the lowest possible weight are the features of this competition model.
Available in both Compe-R and Compe-D configuration, drivers are given the choice of rigid or damper discs depending on their needs. Both however come equipped with a lightweight forged aluminum clutch cover and ultra-light drilled chromium-molydenum flywheel, which allows us to achieve the lightest possible setup. Additionally, the grooved center plate provides improved disc release for better disengagement at any RPM.
Hyper Carbon Series
The flagship model of EXEDY clutches, the Hyper Carbon Series. In 1995 EXEDY supplied carbon clutch products for use in the pinnacle series of motorsport; Formula One. This same technology is now applied to carbon clutches developed by EXEDY for use on the street and track. These clutches are lightweight, durable and resilient to high heat, contributing to an improvement in track times. Available in single, twin and triple designs with both rigid or damper discs for a full range of power holding capacity.
EXEDY carbon discs are able to perform through long durations of high rotational velocity due to our precise application of carbon. The fibers are set one-by-one in a weaving pattern and baked at more than 3600°F, finalizing the strengthening process. Heat expansion rate is 1/20th of iron therefore eliminating a change in clutch feel that may happen due to distortion caused by expansion during driving. Carbon material also possesses a “non-stick” characteristic that eliminates disengagement problems.
Hyper Builder Series
The new EXEDY Hyper Builder Series allows the racer or custom car builder to assemble a clutch kit to fit their specific application. These kits are similar to our Hyper Multi Plate kits, but are supplied WITHOUT a flywheel. The Builder Kits can be used with any of the available flywheels or with your custom made flywheel to match an EXEDY kit to virtually any transmission.
All EXEDY Hyper Builder Series kits all come with HD clamp load and a push type diaphragm for use with a 44-54mm release bearing. The lightweight cerametallic clutch discs are all 200mm diameter with solid hub for reduced mass and high torque holding capacities. Clamp load on every kit is a pedal friendly 2653, which holds 615 torque on twin setups and 923 torque on Triples..
