330 Tire Motorcycle Swingarm Conversion Kits for 2008-11 Twin Cam Softails


Our 330 tire motorcycle swingarm kits are bolt on replacements for the stock 2008-11 Harley  Softail swingarms and they enable you to mount a 330 tire on your stock Twin Cam Softail without doing any modifications to the frame.

Thanks to this innovative wide swingarm you will be able to mount a super-wide rear tire, without any modifications to your stock frame, still keeping front and rear wheels properly lined up for safe riding and great handling.

  • aftermarket rear brake calipers
  • Harley-Davidson OEM rear brake calipers
