PTT 7.25" (184mm) Clutch Combination
The 7.25”/184mm diameter clutch is the most commonly used diameter for motorsport application, due to its strength and durability and able to cope with a range of motorsport applications at a reasonable cost. The 7.25”/184mm clutch has a significant reduction in inertia over a standard road-based clutch.
It is available in 3 thicknesses; 0.105” (normally used for race), 0.200” (normally for track or rally use) and 0.250” (normally used for heavy duty rally) 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.
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.
