BILLET SERIES Dyna "Speedway" Swingarms

Our ALL NEW Billet Series Speedway 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.
  • Black Anodize
  • Gold Anodize

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


PLEASE NOTE: All Trac Dynamics swingarms are manufactured entirely in the United States and due to the wide variety of arms we make, they are all made to order. Production times can range from 5 to 12 weeks and depend on the model, style and finish of the arm. Please feel free to call if you have a special project or unavoidable deadline, we will see what we can do or what we can offer you.


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