    Positraction units

    We offer a full line positraction units including  following :

    Positraction differentials ensure maximum traction under adverse conditions, they are designed to keep both wheels in a constant drive mode, with the ability to automatically "unlock" to permit necessary wheel speed differentiation. It also eliminates individual wheel spin for better traction and less tire wear.

    Gear Ratio Guide for Larger Tires (click image to see enlarged illustration)

    gearratiochart_large.jpg

    To determine your existing gear ratio:

    Place transmission in neutral and elevate one tire. Mark tire and driveshaft, turn tire two complete revolutions while counting number of turns of the driveshaft. This is your Actual Gear Ratio. i.e. 3 turns + 3.00 ratio, 4.1 turns = 4.1 ratio, etc.
    Example

    Existing gear ratio and tire size (Dia. in.) 307 ratio and 30 in. tall tires = 2060 engine RPM @ 60 MPH
    Other Formulas that might be useful!

    Ratio = (rpm x tire diameter) divided by (mph x 336)

    RPM = (mph x gear ratio x 336) divided by (tire diameter)
    MPH = (rpm x tire diameter) divided by (gear ratio x 336)

    Tire Diameter = (mph x gear ratio x 336) divided by (rpm
