This versatile swing arm is intended to fit our mag style drive wheels with drum brake assembly (as pictured).

For use with other wheels, please check the dimensions provided, to be confident it will fit your needs.


  • welded box & plate steel.
  • durable powdercoat finish, color of parts shipped may vary.


  • Integrated boss (prevents brake plate assembly from spinning when brake is applied)
  • two M10 threaded inserts for connecting braces, shocks, or other attachments.
  • two pivot axis plates with 12mm (1/2") holes, for mounting to frame. 



  • Space between the axle drop-out slots (width) is approximately 135mm. Width is somewhat flexible.
  • Axle drop out  slots accept our alloy wheel assemblies with integrated brake systems (which include an axle which narrows down to an 11mm diameter at the drop-outs). A drop-out edge may need to be ground if using slightly larger axles.
