With most high performance clutch kits you must sacrifice drivabilty and long wear by going with a puck style clutch, Most pucks will only last 10,000 -15,000 miles and can wear out in less than 7,000 miles when driven hard. Do you really want to change you clutch that often?

In our search for a clutch that can take the abuse of Aggressive street/track and auto-X , Drive smooth on the street and last a very long time we now offer you the "TZR" clutch kit.

This clutch features a very light weight disk for super quick shifting! Disk weighs only 2.5 LBS VS a normal full face disk weight around 4.5- 5lbs and is still much lighter than a sprung 6 puck which reduces disk inertia and allows easy High RPM shifts!

!
A Segmented kevlar lining provides extremely long life and durability.


This kit will give you all the advantages of a puck disk without sacrificing clutch life and drive-ability!

• Extremely Light disk weight, Much easier on transmission and syncros

• Quick/Full Clutch release

• Smooth Starts

• 300% longer life than organic clutch linings

• Since there are no metal or abrasive particles in the friction material, Kevlar significantly reduces flywheel wear
• Offers extremely fast shifting at high RPM

• Dynamic coefficient of friction: 0.36 µ ± 0.1 in the  200° F - 650° F range.
• Wear rate: 1/5 to 1/10 that of asbestos materials, 1/2 to 1/3 that of sintered bronze materials

• Composition: 100% long KEVLAR^® fibers and proprietary polymer binders. Includes no metal, no abrasives, no cotton, and no fillers.
• Density: 0.91 g/cu. cm (0.033 lb./cu.in.)
• Thermal conductivity: Extremely low
• Shock resistance: Excellent (does not crack, or break)
• Lubricant contaminant resistance: Does not degrade
• Abrasiveness: Non-abrasive to opposing iron, steel, and copper surfaces

Why is Tribco Kevlar Friction Material Superior?

Simply put, it is the world's first friction material that utilizes long KEVLAR^® fibers in 100% levels. KEVLAR^® is a man-made fiber that offers an incredible combination of high strength, nonabrasiveness as well as resistance to heat and tearing. That's why KEVLAR^® is used in demanding applications as varied as bulletproof vests, army helmets, boat hulls, radial tire belting and composite aircraft.

Other companies have tried to use KEVLAR^® in friction materials but could not break away from traditional manufacturing techniques such as molding. But the only way they can mold KEVLAR^® is to grind it into a pulp—unfortunately, molding severely limits how much KEVLAR^® they can use. Additionally, grinding up KEVLAR^® reduces its strength, wear resistance and tolerance to heat.

Recognizing these problems, Tribco set out to find a new way of making friction material. The result was a revolutionary textile sheet-making process that utilizes long KEVLAR^® fibers in 100% levels.

But there is more to the story. Tribco also found a new polymer resin that the U. S. space agency NASA developed for heat resistance on reentry vehicles. Tribco then developed a process to use this high temperature resin as a binder in its friction material. This is a major breakthrough because the resin, a polyimide resin, has much higher heat resistance than the phenolic resins used in standard friction facings.

The New Segmented Kelvar material used in the TZR clutch kit is not the old cheaper grade kevlars that can easily glaze, This new generation Kevlar material is segmented for better heat dissipation, Highly resistant to glazing, Will handle hard use and an excellent choice for smooth operation in high powered cars even with heavy track or Auto-X use.

Break-in period of 500-1000 miles during which slippage may occur.  Care must be taken during this period not to overheat from excessive slipping.  We strongly recommend no more than 1/2 throttle and no hard launches during this time. After this material is burnished in you may resume your high performance driving.
