 icencic Posted:

Excellent performance driving on the roads also the price!

 mabaususa Posted:

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.

 mabaususa Posted:

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.

great upgrade,the firm no dive front end I remember when I first got my 1986 liberty HD.

 Squatch Posted:

Made a huge difference in the way the bike rides. Front end doesn't rise and fall when shifting through the gears any more. Feels more connected to the road. Install wasn't too bad. Should have done this long ago

Installed tubes on a 2002 Harley Road King. Awesome set-up. Gonna spread the word on this product.

 Gitcho Posted:

A good fix for the front end dive problem associated with braking on the 2009 FLHTCU. You would think this problem would not have gotten past the Quality Assurance folks at the plant.

 gusotto Posted:

I just added the PS Cartridge System and with even a short ride, I can feel the difference. Bike feels more planted. Can't wait for spring when I take a long ride to the coast. I have PS f/r on the Sportster, now I'm f/r on the Ultra. Really makes a long ride easier.

the only way to go for the front end

Put them in my '03 Deuce, major difference in handling and they sure stopped the nose dive.
