Radius Ball Kit

 

The authentic style radius cap assembly. A loose radius ball cap can cause steering problems. Fits 1928-31. Lower cap is powder coated black. The only American made kit on the market today!! Ours fits! Note: Radius Ball Assemblies, from the factory, the model had the A-3440-S style radius kit. The A-3440-RE kit (Replacement Ball Cap) is a replacement style kit that was offered by aftermarket companies at a later date. The A-3440-RE kit uses a rubber ball to take up slop from a worn radius ball.
