1947 - 1959 Front Disc Kit 

Our kit will not work, if you have an aftermarket steering arm shown in the photos on this page. (Minimum Rotor Thickness 28mm) (Save your original hubs & bearings. Our rotor slips over your stock hubs.) Remember.. it fits most 16" Single Disc Brake Style Wheels and larger. It will not fit 15" Single Disc Brake Style Wheels. ​ ​Our kit may fit as early as 1943 with a .920 King Pin. Measure spindle bolt pattern and confirm the king pin if earlier than 1947.

​*When converting from drum to disk. You will need to cut and re-flair your existing hard brake line or bend new ones. These are not supplied.
