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

Includes:Flywheel

If you've modified your engine and substantially boosted horsepower and torque, a single-plate clutch may simply be inadequate to prevent slippage under full throttle. EXEDY has the solution for engines that deliver as much as 500 lbs.-ft. of torque by doubling the number of plates. The extra friction area also permits using a smaller-diameter assembly for less inertia. 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 dampened hub, combined with the lighter weight of the whole assembly may make stating 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:

  • Double the torque capacity with dual friction plates
  • More friction area means a smaller diameter assembly for less inertia
  • Quicker shifts and faster lap times
  • All multi-plate clutch kits come with lightweight chromoly flywheel
  • Purple anodized forged aluminum cover
  • SFI approved for racing
  • Spring damper discs
  • Carbon friction material

    Amazing but quality changed
    Size: Large, Color: (002) Black / Black / Halo Gray
    Love these socks so much, been buying them for about 4 years now!! Not giving them 5 stars anymore because the quality is different and not as good, durable and thick as before.

    The best no show socks
    The only no show socks I have ever found that do not slide down. These are very comfortable and the extra tab on the back provides comfort by keeping shoes from rubbing the back of your foot. The top of the sock also comes up high enough to cushion the top of your foot all while still remaining hidden while wearing tennis shoes or even with my hey dudes.

    Love it it was perfect for what I needed it for. Good quality!
    Size: 4 Panel, Color: Black
    It like a very dark chocolate brown/black. What I liked most about it is that you just pull it out of the box take the long plastic film off of it and it's ready to go. It has protective feet on the bottom. It's very attractive and it was so easy. It's so nice when you have a product you don't have to assemble.
