Harley Davidson 2018-2024 Softail "Racer" Swingarms

Our ALL NEW Billet Series swingarms feature one piece CNC machined sides custom designed to give you great looks and superior strength! Extensive pocketing on the inside gets the weight down to a minimum making these arms only slightly heavier than our conventional arms. Billet Series arms also include our AXS (axle interchange system) axle adjusters that are manufactured "in house" and made from super hard 7075-T7 aluminum. Our exclusive design allows you to change axle diameters in the future without having to purchase a whole new swingarm all with a weight savings of over 10 lbs. over you stock arm!

Available finishes:

  • Bare/Factory finish.
  • Black Anodize.
  • Gold Anodize.
