Progressive Suspension Monotube Fork Cartridge Kit 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.

Features:

  • 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

Progressive Monotube Fork Cartridge Kit For Harley Sportster 2007-2015 4.7 5 3 3
2014 XL883N (Iron 883) Review Review from a 5'-6" 145lbs rider Miles ridden with monotube kit: ~800 miles Rear suspension: Progressive Suspension 13" 412 series With my weight and rear suspension the recommended 6 pre-load spacers gave me 1/8 inch of static sag!! 5 spacers gave me 1/2 inch of static sag. 4 spacer gave me 3/4 inch static sag. So after taking apart my front fork tubes 3 times I finally got the static sag that I'm happy with. I can feel the monotube kit working over bumps, and is real nice vs stock. Pros: -pre-load is adjustable -improvement over stock -improvement over drop in springs? -no more fork oil changes or leaks Cons: -recommended pre-load is for heavy riders -must take off the fork tubes to adjust pre-load -fork tube cap is part of the damper tube assembly, so will not work with a separate pre-load fork cap for fine tuning overall I'm very happy about this upgrade and would do it again. Also let me get real good at taking apart the front tire, brakes, and fork tubes. June 7, 2016
Excellent upgrade to compliment new shocks. These monoshocks came highly recommended when I was looking to upgrade the forks and installing new shocks. Im not 100% sure that this made the front suspension more comfortable but it definitely improved the handling. I feel like my bike can easily slice through corners and doesnt dive quite as easily when getting on the brakes. Installation was a bit challenging and I recommend using a press or a buddy to compress the shock. April 21, 2016
Top Notch! Best thing I've bought for my 15 iron sporty yet! Stock suspension is horrible on these bikes from the factory. I did the 412's in the rear at 13" and immediatley the front suspension weakness showed even more. I decided to spend the extra coin on the cartridge kit and I'm SOOOO glad I did. I was having alot of wheel drift problems on the highway and other issues with the front end handling. This kit fixed EVERYTHING. The bike is so planted now on the road, world of a difference. Buy the kit and don't look back! Best of all, no need to remove the forks to install on a sporty! August 16, 2015
