PTT 5.5" (140mm) Clutch Combination

CLTC-PTT-5.50

The 5.5”/140mm diameter clutch, due to its small diameter has very low inertia, ideal where rapid throttle response is important. Perfect for use in race and lightweight sprint car applications such as single seaters, where space is a premium. It is also used on high end applications for rallying. 
 
It is available in 2 thicknesses; 0.105” (normally used for Race and sometime Sprint), 0.200” (normally for Sprint, Track or Rally use) with the options of single or multiple plates depending on torque requirement and space available. There is also an option of different spring rates to aid with installation choice.
 
If you contact us with full details of your application, including peak torque and horsepower, type of gearbox and spline, as much information about your installation and intended use, we can then recommend a suitable clutch. All clutches are specially built to order.
 
 
PTT
Power V-Drive System: The angled Power-V drive legs make the floater plates self-centering. It evens out the drive forces in the Clutch and provides for inherent dynamic balance. The resulting increased surface area of the Power-V lowers stress in the clutch as well, allowing longer life of component parts.
 
PTT Proprietary friction materials are state of the art giving smoother engagement characteristics and longer life.
 
Micro finished friction material means no bedding-in required and eliminates excessive Clutch wear.
 
Much lower Moment of Inertia than a stock style clutch and up to 20% lower than other manufacturers’ equivalent racing clutches. This lower M.O.I. allows faster acceleration, decreased Brake wear on deceleration, quicker shifting, and reduced Syncro or Dog Ring wear in your Transmission.
 
Clutch Cover machined from Billet Aluminium. Optimized Clutch Cover design means lower pedal effort, better modulation, driveability and control.
 
Open housing design means better cooling and dust evacuation.
 
Fits into a smaller area due to improved design and flush mounted fasteners. Approximately 0.250” shorter overall than competitors clutches.
 
Tailored to your every element of YOUR application requirements.
 
Precision manufactured in the USA.
