    PTT's 4.5" Power-V racing clutches are the lightest Moment of Inertia (M.O.I.) clutches in our product line. They have approximately half the M.O.I. of our 5.5" clutches. If the rules you race under allow a clutch this small, you cannot afford to pass up this speed advantage.

    The simple facts are this:

    A PTT 4.5" clutch makes your racecar accelerate faster. It lowers the rotating weight in your racecar's driveline, allowing your engine's horsepower to accelerate the car faster.

    A PTT 4.5" clutch also allows the car to decelerate faster without using up more of your brakes. There is less inertia in the drivetrain that the brakes have to slow down so you get more 'engine braking' with a lighter clutch.

    Quicker Shifting. The lower M.O.I. of the clutch discs allow quicker shifting and less wear on the synchros, or dog rings, in your transmission. Lower M.O.I. clutch discs change R.P.M. faster because they have very low stored inertia, causing less stress on transmission parts.

    PTT’s 4.5” clutch has 56% of the M.O.I. of a 5.5” clutch.  4.5” clutches are available in 1, 2, 3 or 4 disc configurations.

    When it is time to select a winning clutch for your racecar, remember:

    Lighter really is FASTER!
