The new Aluminum Diff. Housing Set is made of blue anodized aluminum which helpsprovide a smoother moving action and also looks great as a dress up part. When attached to your F104 machine, it makes maintenance a breeze as it does not come apart when you take off your wheels.
Can be used with F104 & F103 series chassis machines. (For use on the F103, item 54162 must be purchased as the axle needs to be shorter for item 54158 to work at all)
