Excellent performance driving on the roads also the price!


great suspension up-grade


great suspension up-grade


These are the best upgrade I have ever made. Replaced the stock height Progressive springs I installed 2 years ago. These have a much firmer ride and much better handling. Bumps and potholes no longer feel like they might rip my front end off. '06 FLSTF


amazing product ,changed the feel of the bike ,I can now take corners with confidence .ride is firmer and positive .excellent


The difference is night and day between this and stock. No more front end dipping. Handling is great. Totally worth it.


I should have done this a long time ago, the suspension works great!


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.


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.


have to say J&P you are wrong you say this does not fit 2003 fxdwg but I asked progressive and they said it did fit so I bought it from you and it fitted perfect no problem at all and it works great does just what it says on the tin thanks J&P for another great product


Big improvement over factory springs. Took the "jolt" out when hitting large bumps at cruising speed that I felt with stock springs. Better handling at all speeds, just as they stated. Easy installation. Only reason did not give 5 stars is because I don't know the durability of them yet.


Product instructions work well with maintenance manual. Easy procedure to install. I replaced front and rear shocks with Progressive shocks on my 2003 FXST after 110,000 miles. What a difference in ride and cornering.


I put the monotubes on my 02 deuce and was surprised at home much the difference was. At first I thought they were too stiff until I rode for a few miles, then I started paying attention to the usual bumps in the roads on my usual path out of the suburban where i live. I couldn't believe the great feel and no more fork slamming down. And brake dive is now what its supposed to be ,minimal. Thanks Progressive nice job!! And thanks JPcycles for such a great deal and ease of service!!!


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


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.


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.


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.

Perfect resolution for a common nose dive problem.


perfect fit fast shipping.highly recommend jp cycle to my friends


great product, shipped quicker than expected and am enjoying it on my bike now


This product was a great improvement over my stock fork assembly. defiantly worth the money!


Great product. Very happy. Recommend.


Much better handling now. The front end feels like it has less flex and the tire stays in contact with the road better so there was a dramatic improvement in handling.The directions regarding the number of preload spacers to use in very poor in my opinion but watching the Youtube video helps a little. Pretty easy install otherwise.


Had a set on my dog tail they work great lots better than factory


The best money you can spend on your Harley


Great product....Installed in 2 hours in my shop.


Pay attention to your instructions follow them explicitly the results are fantastic I love it . I have 02 Electra Glide I updated it to the new monotube by Progressive really good


As always, Progressive Suspension made an exceptional porduct and JP Cycles provides it at a great price!


this kit is 4 extreme handling..WOW!! LOVIT !! I couldn't believe those lame springs from Harley... these r state of the art control...the cornering,stability,the smoothness on those rough roads is very impressive!!


Great ride


Much better quality than the OEM suspension. During the installation, I realized that the OEM suspension were only springs. Progressive has really pulled it off with this suspension. Easy to install but takes a little time. I used Screamin' Eagle Heavy Duty oil. The suspension feels great. Great improvement and quality!! I also put the 412 12" shocks. Great combination! I absolutely recommend the product.


Fork Cartridges are a must have for any Harley owner. The amount of difference that they make is almost unbelievable. I've owned several Harleys, and this is the first time I've installed them on a bike. I initially didn't even give it much thought, but decided on my most recent scoot to give it a shot. These are worth every penny. I feel much more stable in curves and turns, I'm not experiencing nearly as many of those jaw shaking moments that are found on poorly maintained roads. The front end no longer dives when I stop on a dime either. Using mine with Belray 10w fork oil.


Thanks for this great item and fast shipping I will comeback again Jorge


Great product. I wish preload adjust was easier to adjust. It's a little stiff for me at 150 lbs. probably perfect for average weight rider. This is the 2nd bike I've installed them in and I'll use them on the next bike. Easy install. Great ride.


Great ride


These made a major improvement in ride quality and reduced bottoming to all but the harshest of hits. Installed in less than two hours. The quality and fitment is amazing given the price point. I will definitely recommend these to my friends .


Progressive Suspension has done it again. I now have an AWESOME front end. Very smooth.
