Customer Reviews


The difference in the handling of my '07 FXSTC with the Progressive Monotubes is amazing. I debated on Progressive Springs or Monotubes and am very happy I went Monotube. I did preload for more weight than I should have and had to remove one of the preloads. Follow the manufacturer recommendations... they know what they are talking about.


This is a great product and changed the handling of my 2007 Softail Custom. Thank you J&P for providing a market leading product at a far better price point than other vendors.
