Info

This complete disc brake kit easily installs big 11-3/4" rotors on your 1937-1948 Ford car or 1937-1947 Ford 1/2 ton pickup spindles while retaining the original 5 on 5-1/2" bolt circle.

This kit will work with spindles having either original steering arms or with flat steel steering arms. It will NOT work with forged aftermarket steering arms. Wheels must have 3-7/16" center hole and have been designed for disc brake applications. Will NOT work with early Ford factory wire or steel drum brake wheels. You will need to use a later disc brake steel wheel or aftermarket wheel.
