ZOOM® Performance Products is taking twin-disc technology to the street with their all new D2™ Series Twin, an affordable light-weight clutch with the holding power of a racing twin, the smooth engagement of a diaphragm style single disc and superior durability by applying cryogenic technology.
Most twin-disc clutches engage both discs at the same time, transmitting harsh shock loads into the driveline and producing an abrupt "on-off switch" effect that is hard to control on the street. ZOOM’s® groundbreaking D2™ Twin features their patent pending Progressive Uptake™ design, allowing the discs to engage one at a time for super-smooth operation and the ability to take up to 925lb-ft of torque.
The floater plate features heavy-duty straps for noise free operation and is cryogenically treated along with the nodular iron pressure plate. By applying a cryogenic treatment to the metal friction surfaces, ZOOM® is able to strengthen the molecular structure of the metal to increase durability, prevent heat warpage and stabilize the cover, diaphragm and friction ring.
Matched low inertia discs and your choice of a billet steel or lightweight aluminum flywheel complete this technologically advanced ZOOM® clutch system.
Each D2™ Twin system comes fully assembled with high tensile strength fasteners. The stack height is designed into the unit for use with stock release bearing set ups and eliminates the need for shims, making installation a snap.
Since 1966, ZOOM® Performance Products has been the leader in performance clutch engineering and innovation for muscle cars, modern performance cars, racecars and diesel trucks. ZOOM® is headquartered in Timmonsville, SC. To learn more about this or other ZOOM® products, or to find an authorized distributor, visit http://www.zoomperformance.com/.

Perfection Clutch was recently named "NAPA Under Car - Supplier of the Year” at the annual NAPA National Sales Meeting in Dallas, Texas. Mike Robinson, general sales manager for NAPA Under Car, noted upon presenting the award that "Perfection is not our biggest supplier.....they are our best supplier". Also according to Mike, in a letter sent to Perfection Clutch president Jim Ott, he said “It was viewed by our entire team as well deserved recognition; of the fine support you (Perfection) gave us (NAPA) throughout 2007.” In his letter he went on to quote what some reps in the field had said about Perfection when solicited for comments. Here are a few of those comments.
“They (Perfection) are always ready to train, give clinics, or promote their line!"
"The plant visits are well planned, and impressive...they truly appreciate the NAPA customers we bring for a visit!"
"Our large ATP Group is so pleased with their changeover to Perfection!"
Perfection Clutch is deeply grateful for this prestigious award and is already hard at work earning the NAPA Under Car Supplier of the Year award for 2008. They plan on doing this by continuing to provide excellent customer service and superior products as well as educate the customer and end user of the great importance of servicing the entire system when replacing a clutch. A clutch system will only operate as good as the weakest link in the entire system. The overall clutch system will last longer when all of the components that make up the system are replaced at time of clutch installation.

Dodge made a mid-year change to the transmission, flywheel and clutch assembly for 2005 Dodge Ram 2500, 3500 5.9L Diesel trucks. The clutch sets and flywheels are not directly interchangeable and the correct sets must be selected for servicing. The question is...which transmission does the truck have in it? The two choices are a NV5600 or a G56 transmission.
The NV5600 has a cast iron case like in the image shown below.
The G56 transmission has an aluminum case like the image below.
The next picture is the easiest way to identify which transmission is in the truck without getting under the truck. Just get in the truck and you will see that the G56 has reverse located to the LEFT and DOWN and the NV5600 has reverse located to the RIGHT and FORWARD. Pretty easy, right?
Using these qualifiers will help you sell the proper clutch for the 2005 Dodge 5.9L clutch system. The G56 uses a MU72179-1 (shown below)
and the NV5600 uses a MU2023-1 (shown below).

On December 25, 2007 Berkshire-Hathaway Chairman and CEO Warren Buffett and Tom Pritzker, Chairman of Marmon Holdings announced that Berkshire will purchase 60% of Marmon Holdings, Inc. Perfection Clutch is one of the one hundred and twenty-five companies held by Marmon Holdings, Inc.
Welcome to the first edition of the Friction Zone. This series of articles is so titled because what occurs within the Friction Zone directly determines proper clutch feel and function in addition to the ability of it to transmit power from the engine to the drivetrain. The Friction Zone is the range of driver control from a totally released clutch to full engagement of the clutch. It is used to start a vehicle in motion from a standing start both forward and reverse. During this time the driver must be in control of the vehicle, not a chattering clutch in control of the vehicle. This is when chatter would occur, and it interferes with the ability to totally control vehicle speed and position. Chatter, its causes and prevention, will be a future subject for the Friction Zone. The picture at the top represents the pressure plate just beginning to touch and compress the friction material facings and the marcel cushion springs in between them. This compressible section along with the friction material creates the “Friction Zone”.
FORM, FIT & FUNCTION
Figure 1 - C47801 Variations
One of the issues customers are often confused about is why the parts removed do not look like the ones being supplied in the new clutch set. Take a look at one of our most popular applications, the Ford Ranger, which uses a C47801 cover assembly. This cover is used in MU47801-1B, 1C, 1E, and 1F clutch sets. Due to the popularity of this range of trucks, almost every company that manufactures clutches offers a cover assembly for this application. This allows for a lot of potential confusion in the field when a customer attempts to match the old to the new. Take a look at the examples in Figure 1.
The collection in the image shows seven different part numbers from six different countries. One variation was not available for the picture. That would make it 8 variations for one application!
Figure 2 - Lever to Table Dimension
How does this affect the customer and countermen? Only two of them look alike. The others are all built from the standard designs that these various companies like to use. All of them fit the flywheel and all work within their respective designs and specifications, but most of them would raise an eyebrow or two at the counter. This is where the fun usually begins. Out comes the 12” ruler, tape measure or even a pencil as a gauge. The customer and countermen should be truly commended for trying to figure this part out, but it cannot be done on the counter by comparing measurements of un-installed clutches. The cover assembly must be correctly mounted to a flywheel using either a new clutch disc or precision steel gage blocks like used in the Perfection Clutch Development Lab. Then the clutch should be cycled (engaged and disengaged) several times. Only after cycling, can one accurately check the Lever to Table dimension or diaphragm spring lever tip height (see Figure 2) and plate lift at the specified release travel and see if the system releases. Note that the plate lift at the specified release travel is not a published number. One would have to tear this setup down and set up the other seven systems and repeat the entire process to get true comparison numbers. If the customer has any doubts about the fitment of parts please do not hesitate to call the Perfection Clutch tech line at 800-258-8312 ext.4. They can provide you with all the information you need to verify a part and save you lots of time.
The only bench comparison that is possible to measure is the inside diameter (ID) and outside diameter (OD) of the pressure plate casting. Also, it is possible to compare the bolt pattern and dowel pin pattern. Even this simple comparison can cause confusion due to staggered or offset dowel pin patterns (i.e. Nissan, Honda and Toyota). Do not forget that GM, Ford and Dodge often use 2 or 3 smaller bolt holes that act as pilot holes for special shoulder bolts. One of the easiest ways to compare confusing bolt or dowel pin patterns would be to trace the pattern on a piece of cardboard using a fine point pen or pencil. Note that dowel pin holes are usually evenly spaced between the bolt holes, or adjacent to the bolt holes. Once traced, place the cover being compared on the pattern and rotate the clutch to find the matching pattern.
Clutches can be very confusing to understand and it can only help the process if the parts do the best possible job in terms of function. It is a real plus when they match Form and Fit at the same time.
1979 DAYTONA 500 CALE YARBOROUGH AND DONNIE ALLISON BATTLE FOR THE LEAD
Video below features the famous last lap battle between Cale Yarborough and Donnie Allison in the 1979 Datyona 500. Afterwards, a fight broke out that also included Bobby Allison. The clip also includes interviews with the people involved. It would be awsome if NASCAR racing (not necessarily the fighting part) were more like this today. Is it even possible to make up two laps at Daytona (or anywhere for that matter) without the help of the lucky dog pass? I guess you will have to watch the 2007 Daytona 500 to find out.
Thanks to all the folks who stopped by and visited us at the 2006 SEMA Show in Las Vegas! The show was a great success for ZOOM. It has been one year since we rolled ZVT for diesel trucks out to the industry and this year we introduced ZVT for Mustang and D2 twin disc clutches at SEMA. The twin disc clutch won a best new product award from the international panel of judges. It was a brutal week in terms of the hours and effort but a marvelous week considering the results. Thank you!

1995-2005 Ford Ranger & Mazda Pickups with 2.3, 2.5, 3.0 & 4.0L Eng
Perfection Clutch is proud to announce our new “value-priced” alternative to the OE self adjusting clutch for 1995-2005 Ford Ranger and Mazda pickup trucks. This new design has a lower release load compared to other "non" self adjusting covers offered in the marketplace. The result is an easier pedal effort required to shift and leads to reduced pressure on the clutch release system which reduces wear and tear on hydraulic components. This new design also offers an alternative price to the OEM unit for the value conscious customer. Set number MU72158-1 is a direct replacement for MU1996-1, MU1996-1A, MU70154-1 and MU70154-1A. Set number MU72159-1 is a direct replacement for MU1996-1B and MU1996-1C.

Exciting New Clutch for Dodge and Ford Diesel Trucks! TIMMONSVILLE, SC (October 22, 2005) – ZOOM® Performance Clutches is proud to introduce ZOOM Variable Torque (ZVT™) clutches for Ford and Dodge diesel trucks.
Patent pending ZVT™ clutches add clamp load by applying centrifugal force to the pressure plate as RPM of the engine increases. Each unit is designed with consideration to the application’s peak torque RPM range. Additional clamp loads of over 700 pounds can be achieved within these ranges. With a ZVT™ cover assembly, one can expect torque handling gains of 300 lb-ft or more with organic friction material and well over 600 lb-ft with ceramic button friction materials. The main benefit, other than more clamp load and torque handling ability, is the clutch pedal will feel stock and will not overload clutch release systems or engine thrust bearings.
Plans are currently in the works to extend this new technology into the Mustang and Sport Compact markets.
If you would like information on where you can buy ZVT™ clutches please email our Sales Department or call us at 1-800-258-8312.
Today I would like to talk about torque and how the torque handling ability is calculated for an automotive clutch.
The formula looks like this:
Torque Capacity (lb-ft) = F ● Rg ● N ●µ
The torque capacity of a clutch can be calculated if the following four values are known.
1) F = Clamp load applied by the cover assembly in pounds (lb). 2) Rg = The mean radius, or radius of gyration, of the friction material in feet (ft). 3) N = The number of friction surfaces, one disc has two surfaces. 4) µ = The coefficient of friction of the facing material.
Let's go through them in order.
First of all, the clamp load applied by the cover assembly will be something that the manufacturer or distributor will have to give you. This number can range from (but is not limited to) 800 lb. to 3,200 lb. For our import car example we will use 950 lb. Special equipment is needed to calculate this number. Contact us here at Perfection Clutch (Makers of ZOOM Performance Clutches) and talk to one of our ASE certified tech guys. They should be able to tell you the clamp load number for the cover assembly in your particular vehicle.
The second variable is the mean radius of the of the friction material in feet. This is also known as the radius of gyration. At first glance it might sound simple to calculate but it actually involves a few steps. I will go through an example of how to calculate it. The first thing you need to do is measure the outside diameter of your clutch disc (a.k.a. driven disc) in inches. Then measure the inside diameter of the clutch disc (at the edge of the friction surface) in inches. The Radius of Gyration in Feet = Square Root of (Outer Radius in Feet Squared + Inner Radius in Feet Squared / 2) . Note that this formula says RADIUS of gyration in FEET. Remember that your diameter numbers will have to be coverted from inches to feet and then divided by two to get the RADIUS in FEET. For example, if you have a clutch disc that has outer and inner diameters of 8.35" x 5.91" respectively, then that would translate into radii in feet of 0.348' x 0.246' respectively. Then we plug these numbers into the radius of gyration equation. The Radius of Gyration in Feet = Square Root of (0.348' squared + 0.246' squared / 2). The final number for this example would be 0.30 ft.
That pretty much takes care of the complicated stuff. Next you would need to know the number of friction surfaces. 1 disc = 2 surfaces, 2 discs = 4 surfaces, 3 discs = 6 surfaces...... You get the idea. The example here will have 1 disc (N= 2 surfaces).
The last number you will need to know is the coefficient of friction of the disc's facing material. In general, the following numbers can be used for Perfection Clutch and ZOOM Performance Clutch Products:
Coefficient of Friction numbers can vary from manufacturer to manufacturer but these numbers are well within reason for the types of material listed and should also provide a slight safety factor which means that each material might have a slightly higher coefficient of friction at lower operating temperatures. Our example will use a stock coefficient of friction of 0.25.
These 4 values can now be entered into the formula and multiplied to determine the torque capacity of this particular import car system.
Clampload = 950 lb. Mean radius in feet = .30 ft. Number of friction surfaces = 2 Coefficient of friction .25 (organic facings)
950 lb. ● .30 ft. ● 2 ● .25 = 142.5 lb-ft
As mentioned earlier, this value includes a designed in safety factor that is in excess of the expected maximum engine torque.
If you need assistance, don't hesitate to give Perfection Clutch a call at 1-800-258-8312.
Improper release bearing installation of this nature is a common occurrence that can be easily avoided. The fork and spring clips must be installed between the two flanges of the collar of the release bearing.
If improperly installed: 1) Clutch will NOT release correctly. 2) Release Bearing will fail prematurely. 3) Damage may result to other parts of the drive system.
