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.

Upgrade your Harley-Davidson Dyna's front end with Progressive Fork Springs, engineered to deliver a superior ride. These springs feature a progressive rate that adeptly absorbs minor road imperfections while providing robust support for heavy braking and larger impacts. Enjoy enhanced control and comfort on every ride.

Why riders pick this

  • Progressive rate absorbs small bumps, resists brake dive
  • Precision-wound construction for consistent performance
  • Available in Standard and Heavy Duty versions
  • Improves front-end stability and control
  • Backed by a lifetime manufacturer's warranty

Progressive fork springs are a direct upgrade for Harley-Davidson Dyna models, designed to significantly improve your bike's front suspension performance. The progressive rate design means the springs are softer initially to soak up small bumps and road chatter, then gradually firm up as they compress to handle more aggressive riding, hard braking, and larger impacts without bottoming out.

Responsive Suspension Performance

  • Progressive spring rate effectively absorbs small road bumps
  • Maintains firmness to control front-end dive during braking
  • Precision-wound construction ensures consistent performance and durability
  • Available in Standard and Heavy Duty versions to match your load and riding style
  • Backed by a lifetime manufacturer's warranty for peace of mind

Choose Your Ride Style

Whether you're a solo rider looking for a comfortable cruise or frequently ride two-up with luggage, Progressive offers both Standard and Heavy Duty spring options to perfectly match your needs. The Standard version is ideal for solo riders and lighter loads, while the Heavy Duty springs provide the extra support required for heavier riders, passengers, or loaded saddlebags. This upgrade is a foundational step toward a more controlled and enjoyable riding experience on your Dyna.

Common questions

What's the difference between Standard and Heavy Duty versions?

The Standard version suits solo riders and lighter loads. Heavy Duty is stiffer for two-up riding, luggage, or heavier riders, providing more support.

Will these reduce my front-end dive when I brake hard?

Yes — the progressive rate is specifically tuned to minimize front-end dive during hard braking while maintaining ride comfort over bumps.

Are these springs a direct replacement for my Dyna?

Yes, these Progressive fork springs are designed as a direct replacement for Harley-Davidson Dyna models with stock fork tubes.

IF Big...Go Big (Heavy Duty)

There are multiple reviews and recommendations for Standard or heavy Duty 11inch shocks out there. I have these on a 2015 HD Street Bob. Unfortunately the review I read recommended standard for someone 275lb and under. I'm 250lbs and bottom out/drag pipes in the faster turns with the standards on the 5 setting. These shocks look and ride great. I don't regret the purchase, regardless.

Even better than I had expected!

These shocks look and feel amazing! I weigh 190 and only ride 2-up occasionally but decided to go with the 12.5" Heavy Duty shocks anyway. This proved to be a great decision as they are nice and stiff for aggressive riding but handle the road with ease.<br /><br />Side Note: To spite the photographs, the black shocks do come with the skirts on the bottom like the chrome shocks that are pictured. If you do not want the skirts on then you will need a spring compressor from Progressive to remove them. It is a very easy job with the correct tool.

Nice easy mod

These shocks are the best entry level customs you can buy! Super easy install. Night and day difference in ride and handling from stock. This is also a great way to raise or lower your ride in the 2-3 inch range. If you plan on riding 2 up or weigh over 250, you should consider the Heavy Duty. Peace

Better cornering

I bought these for my 13 streetbob to raise the bike. I purchased 13.5 inch springs and the handling increased dramatically. At slow speeds the bike does like to tip more but this helps in the corners. Bike hugs much better and makes it so I only scrape the controls and not my Vance and Hines ProPipe.

Dropped my bike perfect so I could flat foot

Look amazing on my bike but def stiff for me. Kinda wish I got the standard and not heavy duty. I’m 180lb on a 06 Dyna wide glide.

Good fit

Easy install and looks good on my bike. I can tell the ride is better. Still early for a full review. Good bang for your buck.
