Application

  1. Ford 1928-48 spindles are generally your best choice when using an original Ford axle or spring behind application using 37-48 Ford spindles.
  2. Chevy 1949-54 spindles are specifically designed for use on tube axles. A shorter, thicker axle stub makes this a slightly stronger spindle ideal for use with heavier street rods.
