The AA-4 series of Front Adaptors are designed for the same bolt pattern as the Arrowcraft Magnum series. They allow you to use the same dual style wheels on the front axle, giving your truck a complete dually look. AA-4’s accommodate both 2- and 4-wheel drive trucks.
Trucks with dual rear wheels will require the use of a special dually wheel adapter. These parts have been made to work specifically with Dynatrac’s Free-Spin kit.
