Trucks with dual rear wheels will require the use of a special dually wheel adapter; part number AA4DDT. These can be purchased through Arrowcraft (248-280-0210) and have been made to work specifically with Dynatracs Free-Spin Kit... Also, this Dynatrac Free-Spin kit will not fit with most 2014-2019 factory RAM wheels. Please click here to download a fitment notification for more information. The issue is the wheels are closed and do not have a removable center cap which is required to allow the hub snout to pass through. The customer must have a wheel with a center-hole or removable center cap. Dynatrac does not recommend modifying any part of the wheel. This will decrease the strength of the wheel and can lead to catastrophic failure. Dynatrac has confirmed the fitment of the following wheels: RAM Power Wagon, 2010-2012 Factory RAM wheels, AEV RAM wheels, BMF RAM wheels.
