Hyper CARBON-D clutches are the next generation-a 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". Superior engineering enables this system to posess 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.

Notes

  • All referenced torque ratings are measured at the wheels
  • SFI 1.1 Approved - Certified for use in Competitive Motorsports
  • Use with 1991-1996 Style Transmission Input Shaft

Includes:

  • Clutch Cover Assembly
  • CD Assembly
  • Flywheel
  • Cover Bolt SE
  • Flywheel Bolts

EXEDY's forged aluminum pressure plate delivers a higher clamp load than the stock clutch without a significantly higher pedal effort, because the stiffer forged cover allows all of the pedal travel to be utilized to disengage the disc. A stamped steel plate is spongier, taking up some of the pedal travel as it flexes. The stiffer forged cover allows the use of a stiffer diaphragm spring, pivoted differently inside the cover for more mechanical advantage. The increased mechanical advantage lowers pedal pressure, while the lack of lost motion permits normal pedal travel. The bottom line: more torque-holding capacity and great feel at part-engagement. An additional feature of the pressure plate is a series of turbine-like, airflow-enhancing vanes that keep the clutch cooler under extreme operating conditions, which improves durability.

The heaviest components of the clutch system are the clutch cover, plates and flywheel. Low inertia discs allow the transmission to synchronize in a shorter interval of time, eliminating time loss during shift changing while also reducing stress on drivetrain components. The weight of a carbon clutch disc is one third that of a metallic disc.

For most streetable applications, the preferred clutch disc is the cerametallic style with a damper hub. This style of disc will have a consistent feel throughout the day, from the first cold start of the day to a launch from the Christmas Tree after a heat-inducing burnout. The damper hub will help with a smooth launch and improved gearchange feel, as well as eliminate gear rattle moderate speeds. Gear rattle is caused by variations in crankshaft rotational speed, as individual cylinders fire. That in turn makes the gear teeth bounce and rattle against each other as you head on down the road.

A more ambitiously-modified vehicle, used mostly for drag racing, autocrossing or rallying might benefit from the use of a Carbon-D friction disc, Faced with pure carbon-fiber, laid one strand at a time and baked at 3600° to cure, carbon fiber has an interesting characteristic: it's coefficient of friction (COF) gets higher as it gets hotter. Unfortunately, it's inconveniently low when at room temperatures, rising to the same COF range as cerametallic friction material when warmed properly. Used in a street vehicle, its inconsistent takeup may be annoying in a daily driver. Carbon fiber is very long-lived in heavy-duty use, however. Carbon-D friction discs have a spring-dampener hub for easy shifting and quiet gears. Carbon-D is equipped with a new dual stage damper, a low-load stage and rapid-acceleration stage, both of which are individually tuned for each car type.

For a dedicated race or track car, Carbon-R friction is preferred. The lack of a dampener hub may mean a fair amount of harshness, vibration and noise may intrude into the cabin or be felt in the gearshift or clutch pedal. The undampened hub, combined with the lighter weight of the whole assembly may make starting up difficult to do without some initial judder. The advantages in shifting speed and torque capacity are the payoff for this lack of refinement.

Due to the inherent properties of the carbon material, EXEDY suggests the proper way to bring the discs up to operating temperature. The correct method is three sequential five second "slips" of the clutch within 30 seconds at low RPM. This will heat the discs so they will hold the specified torque rating.

Features:

  • Average of 40% increase in clamp load over stock
  • Extra capacity handles street/race car power upgrades
  • Forged assembly is far stiffer than stamped-type
  • Incredible strength means no clamp-load deflection
  • Integrated turbine-like fins enhance airflow, keeping clutch assembly cooler and extending component life
  • Forged Chromoly Flywheel
  • Combination of low weight and high heat capacity
  • Designed for Rally, Drag and hi-performance Street
  • SFI approved for racing
  • EXEDY exclusive friction composition
  • High friction-coefficient material
  • Designed for low wear and high heat resistance
  • Reduced diameter damping disc for reduced inertia
  • Patent Pending disc system
  • Race or extreme street applications

    Not good for an aggressive chewer
    Color: 1PC
    This toy is not indestructible. My little Aussie had one ear off and its neck cut in less then 6 hours and by the next day he had the foot chewed off. It is cute and he loved it, but it is stuffed and not really safe for an aggressive chewer.

    It is not a good product for a dog. I didn’t even last five minutes.

    I received this package and I just gave it to my dog. Doesn’t last five minutes. It’s already tore up.

    Totally worth the good price!
    Size: 6 inch (Pack of 1), Style: Rabbit
    My little shi-tzu has a favorite toy. It’s a stuffed lamb that she has, over time, completely torn to shreds. I needed something cheap on another order to get same day shipping, and I’m now tickled to pieces that I thought to find her something new to play with! When the box arrived, I called my little Mocha and built-up the opening of the box letting her know she had something in there. We never really get to buy her anything, so this was just too much fun 😂 As soon as I picked it up, I planned to toss it for her cause she loves to fetch things. Yeah, didn’t happen. She was so excited, she had this bunny out of my hands before they made it out of the box! Love that it’s made for dogs, and comes without things you might need to worry about, like eye buttons popping off, etc. The little tail did come off pretty quickly and since it was small, I tossed it. The bunny itself is played with at least once or twice daily, and she hasn’t broken through to the stuffing yet. So, for a cheap dog toy, it’s holding up really well. Happy with this purchase and would order something from them again.

    Adorable, but probably not for medium+ dogs
    Size: 6 inch (Pack of 1), Style: Rabbit
    I got this for my 20 and 30 pound dogs to play with, and though I didn't really expect for it to be a durable or long-term toy for them, I think it felt like it was well-made and would probably suit dogs that are up to 15 pounds the best. It felt better than other dog toys in this price point but was filled with holes already after the first time my dog played with it on his own, which I think is probably more of a fabric issue than an actual quality issue, because it was more of a teeth puncture than seams ripping. I hope this helps! I would definitely recommend it to anyone with a small breed dog who doesn't have the same bite strength .

    My dog loves these
    Size: 9 inch (Pack of 1), Style: Bone
    My dog usually doesn’t play with toys but I decided to try this one. She loved it so much that I ordered 3 more to have on hand! Some of the stitching on the first one is coming apart but it’s actually quite durable given how tough she is on it.
