    FITMENT CHECK

    animation comparing factory differential cover size vs Banks Ram-AirDownload and print out the fitment guide to check for clearance. When using this guide for fitment, make sure that either (a) your truck's full weight is on the wheels, or (b) you lifted the truck by the diff. When the truck is lifted off the ground, your swaybar (if you have one) moves and may cause a false fitment reading.
