Hyper Single Series Clutch and Flywheel Kit (Carbon-D)

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.

6-Puck Cerametallic Disc

High friction coefficient, low wear, and a special heat resistant material [T5001] has been applied to enable the clutch size to be reduced which in turn lowers mass inertia and improves shift responses for faster gear changes particularly in racing applications. Durability is improved with the use of a stronger, smaller damper disc, designed especially for the Hyper Single clutch.

Carbon-D

The next generation of clutch systems by EXEDY is the Hyper Carbon-D, the revolutionary carbon clutch system. Carbon-D was developed to achieve the ultimate goal of comfort and streetability by absorbing noise and vibration emitted from drivetrain components such as the differential, transmission and engine. The Carbon-D system is designed to protect the drivetrain by absorbing and dissipating “shock torque” by utilizing EXEDY Patented Technology. Superior engineering enables the Carbon-D clutch system to posses an ideal clutch engagement position, increased clamp loads and lower pedal effort, while the unique carbon fiber friction material allows comfortable half-engaged clutch operation and responsive gear changes. The EXEDY Hyper Carbon-D is available in both single and twin clutch configurations.

SD/HD Type

This model has been developed for high powered street cars and race cars with up to approximately 600TQ @ FW. They feature ventilated, thick intermediate plates for improved life and spring damper discs to protect your transmission and drive line. “HD” kits have slightly high clamp load than their “SD” counterparts and have approximately 20% higher power capacity.

SR Type

These clutch covers are designed to achieve a clamping load that is approx. 40% higher than the genuine part allowing a higher torque transmitting capacity. Ductile material is used for all pressure plates and, high burst strength can be achieved in all temperature ranges.

HR Type

This model has three plates and is developed specifically for high power applications such as over 800 ft/lbs of torque at the flywheel for drag racing. It handles high torque loads and shifts smooth, and because of the lightweight clutch discs, you can reduce your shift times.

EXEDY Lightweight Flywheel

EXEDY Lightweight Flywheels combine low weight, low inertia and high thermal capacity. They are designed for light to moderately tuned racing cars for drag racing, autocross and rally events, as well as street usage. They are made from solid one-piece billet chromoly steel or chromoly steel forgings. They are specifically designed to reduce weight and inertia for better engine response. Most incorporate special design features to enhance the airflow which improves the cooling of the clutch.

The ring gear teeth are integrated onto the flywheel unlike an aluminum flywheel where the ring gear is pressed onto the flywheel and has the possibility of separating from the flywheel due to the different expansion coefficients of aluminum and steel. Newly available are lightweight, solid replacements for vehicles fitted with OE dual mass flywheels. EXEDY lightweight flywheels have passed engineering tests to 15,000-18,000 RPM. They are guaranteed not to fail to the said RPM, and are all SFI approved.
