Progressive Fork Cartridge Kits For Harley Sportster

True high-performance front suspension has finally made its way to HD. Progressive's state-of-the-art Monotube Fork Kit represents the pinnacle of front end handling. High performance specialty components replace the sloppy open bath damping found in HD forks. The kit features a set of gas charged monotube dampers and a set of custom tuned fork springs so you can convert your bike to cartridge forks whether you have dual damper rod forks or a damper rod/cartridge setup.


  • Complete fork internal replacement kit
  • Improved resistance to front brake dive, front end stability & cornering traits, and better avoidance of "bottoming out"
  • Made in USA
  • Progressive spring rate
  • High-quality chrome-silicon wire
  • Precision wound

Fitment Notes & Exceptions

  • Changing ride height can potentially change many carefully-engineered attributes of your bike, including trail and mechanical trail
  • A change in ride height at one end of the vehicle usually will require a change at the other end
  • Prior to purchasing front-end components that are different than your OEM length, please verify that wheel and suspension travel can be altered without causing clearance issues - common interference spots include triple trees, fenders, frame, and of course, the ground.

Great performance; not compatible with adjusters I bought Progressive's Monotube Kit for my 2014 HD 1200 Custom and I couldn't be more impressed. Before, the stock suspension seemed like it worked exactly wrong: I could feel even little bumps in the road hit hard, yet under heavy braking I would get severe dive. Leaning on the front end would easily compress it substantially. Now I find that the ride is both more comfortable and focused. Brake dive is decreased, and the suspension feels much more responsive in the corners. The only disappointment I have with this product is the fact that it is not compatible with preload adjusters. I bought a set of RSD's Misano adjusters thinking they would look trick and also enable me to fine tune the suspension. Unfortunately, the tops of the monotubes are not replaceable. Still if you're debating whether to choose one over the other, go with the monotubes. They're great. June 3, 2014
The Feel is Greatly Improved I replaced the the front and rear shocks on my 2013 Iron 883 and these both completely changed the feel of my bike! If you are going to do one upgrade on your Iron, replace both the front and rear shocks with Progressives. I could ride over a pothole the size of a moon crater and not even have to stand up with the 13" 444s. These fork cartridges dramatically improve the cornering and handling. I can't recommended these highly enough! June 29, 2014
Performance above expectations. Other than the usual headache of removing and refitting the front forks of my 2007 FXST Softail Standard the fitting of these fork cartridges was an absolute breeze. Even before heading out on the road I checked the front compression under braking and was actually surprised at the rate of control. Once out on the road and covering approximately 600km in the first week of around town and open highway riding the performance was impressive since the roads here in Australia quite often go from good to quite horrific depending on the area. Having owned the bike since new the front end has never felt this good. I am more than happy with the outcome and the performance and would not hesitate to recommend these cartridge inserts to anyone. Who has two thumbs up and a big grin on his dial? ME! March 23, 2014
