BILLET SERIES Dyna 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 2024-T8 aluminum. Our exclusive design allows you to change axle diameters in the future without having to purchase a whole new swingarm.

Available finishes:

  • Bare/Factory finish.
  • Mechanical Polish.
  • Black Powdercoat.

Product Info:
  • Dyna models can be used with stock caliper.
  • Arms are available with 3/4 or 1" or 25mm axle.


For a special project, Width, or length, please call 661-295-1956.
