Our ALL NEW Billet Series swingarms feature one piece CNC machined sides custom designed to give you great looks and superior strength! Extensive pocketing gets the weight down to a minimum making these arms a full 10lbs lighter than the stock factory swingarm. 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.
Arms fit Road-Glide/Road-King/Street-Glide models.
02 and later models can use with stock caliper.
Older models must use aftermarket caliper and hanger.
Arms are available with 3/4 or 1" or 25mm axle.
95-01 arms come with spherical pivot bearing kit.
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.
95-01 Road Glide swingarms require the use on an after-market brake caliper and hanger. You can source your own set-up or purchase our PM brake kit below.
