A must have !
They were super easy to install and changed the overall ride tremendously no more front end dive while braking and over all soaks up the nasty pot holes perfectly.

About Progressive
Progressive Suspension has focused exclusively on American V-twin suspension since 1982, and its Monotube fork cartridges and 400/970/970G shock series are among the most common upgrades on baggers and Softails. For most riders the stock rear shock is the single worst part on the bike — this is the fix.
Elevate your Harley-Davidson's front-end performance with Progressive Rate Fork Springs. Engineered to deliver a superior ride, these springs effectively absorb minor road imperfections while providing firm control during aggressive braking. Experience a balanced blend of comfort and handling, all without requiring complex modifications to your V-twin.
Why riders pick this
- Reduces front-end dive during braking
- Progressive rate for balanced comfort and control
- Precision-wound construction for durability
- Works with stock fork internals
- Improves overall ride quality
Unlock a new level of ride quality for your Harley-Davidson with Progressive Rate Fork Springs. Unlike linear springs, the progressive design means these springs are softer at the initial stroke to soak up small bumps, then progressively stiffen to prevent excessive front-end dive under hard braking. This results in a more controlled, comfortable, and confident ride, whether you're cruising the open road or navigating city streets.
Superior Control and Comfort
- Progressive rate design reduces front-end dive during braking
- Precision-wound construction for consistent performance
- Absorbs small road bumps for improved comfort
- Designed to work with stock fork internals
A Foundation for Performance
Installing Progressive Rate Fork Springs is one of the most impactful suspension upgrades you can make to your Harley-Davidson. They provide a noticeable improvement in stability and feel, especially when pushing your bike through corners or coming to a quick stop. This upgrade is an excellent foundation for any rider looking to enhance their V-twin's handling characteristics without committing to a full fork overhaul.

Common questions
Will these springs reduce front-end dive during hard braking?
Yes, the progressive rate design is specifically engineered to minimize front-end squat and dive when you apply the brakes, providing a more stable feel.
Do I need to modify my forks to install these Progressive springs?
No, these Progressive Rate Fork Springs are designed as a direct replacement for your stock springs and work seamlessly with your existing fork internals.
How do Progressive Rate springs differ from standard springs?
Progressive Rate springs offer a variable spring rate; they are softer initially for comfort over small bumps and become stiffer as they compress to handle larger impacts and prevent bottoming out, unlike a consistent rate found in standard springs.

great upgrade over stock
Not much to say, Progressive makes a good spring. A major improvment over the stock springs. I did not have to change the fork oil out and after 3k miles Ive seen no issues. 2012 FXDB.

Progressive Heavy Duty Springs elimintated my brake dive
Replaced stock springs with Progressive Heavy Duty to eliminate or drastically reduce my front end brake dive for which it works very well! My only complaint is that the included instructions said that for my particular bike the spacers should be 5.5 inches. The included spacers are only 5 inches.....So I just took my stock spacers and cut them down to 5.5 inches. No biggie but just a little strange that the included spacers dont measure their recommendation.

Fork spring upgrade
Installed on 2012 FXDF much better ride than stock, smaller bumps are not really felt anymore. Great improvement in ride, definitely a plus for riders over 225 pounds. I wish I had done this a long time ago. Installation was simple and instructions were clear. Spacers didn't need to be cut down.

Very Satisfied
They fixed the diving under braking on my 03. Stayed stock height. Just stiffened up the front end like it is supposed to be. Makes it much easier to control under braking. Highly recommend.
