Description

EXEDY Racing Clutch Hyper Single-Plate Clutch Kit (BH02SD)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

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.

Notes:

  • All referenced torque ratings are measured at the wheels
  • SFI 1.1 Approved - Certified for use in Competitive Motorsports


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

Includes:

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

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.

My dogs love this
My dogs love this stinking toy. I’m about to buy another one though bc they are tearing it up. But overall they are pretty rough with it and suckle on it. I didn’t think this would be such a hit for them but I’m ok with repurchasing it for the amount of love they have for this!

Almost worked!
I have an EXTREMELY destructive Boston Terrier. She loves playing with her toys, but she loves destroying them even more. "Chicken" was her Christmas present and she loved him. She did pull his eyes off right away, fortunately she didn't swallow them, but I was excited that she couldn't immediately shred him. Then she found his weak spot. She managed to grab hold of the tag and tore the seam, and now she just plays with Chicken's torn up husk. He lasted 3 days, which was longer than any other stuffed animal. I would purchase again, but I would cut the tag as short as I could before giving it to her. It was a good run, but I'm still looking for a soft you she can't destroy!

My 18 lb dog had this torn apart in MINUTES
You are going to read this review and think "my dog will be different" just as I did reading some of the poor reviews. I was bamboozled by this product thinking that there must be something special about it and I was poorly mistaken. First off my dog did love this toy right out of the box. Secondly she had it destroyed in mere MINUTES! I was truly stunned. If you feel you must still purchase this stuffed toy after reading my review please find one by this company that is on sale, do NOT pay full price. She had the trim chewed off, a wing off, the squeakers out within 15 min and I am not exaggerating. There was stuffing EVERYWHERE. Was it kind of amusing? Yes. Was I disappointed in the "chew guard" technology? Absolutely. Be warned! If your dog destroys stuffed animals this one will be no different!!

Durable squeaky,eats any toy squeaker gone immediately definitely would recommend
Purchased December still has 2 squeakers working. Never ever had a squeaky that last this long. 25 lb fur baby that finds all especially squeakers. Would definitely recommend I am going to purchase more. Toy boxes is full of stuffy’s with squeakers that no longer work just amazed at the durability and wash as well also

The puppy loves it!
Our new little Rat Terrier, w/ razor sharp teeth and toenails, seems to love this toy. She has learned to squeak the wings and feet, but the belly squeaker is too well buried for her, so when I squeak it, she comes running! After three weeks, it is well chewed, but NO holes in it! Puppies have short attention spans, but she will chase this happily for about 15 minutes, when we're playing Squeak and Throw! Actually, I get tired of throwing it, before she tires of chasing it!
