Product Details

The Progressive Suspension 444-4001B is a 12.5-inch rear shock featuring proprietary patented Frequency Sensing Technology (FST) designed for Harley-Davidson motorcycles. FST allows the shock to sense the frequency of a bump and automatically adjust damping for superior ride quality, whether you encounter small ripples or major road imperfections.

Key Features:

  • Top mount threaded preload adjuster allows for fine-tuning with a simple twist of the cap
  • Adjust spring pre-load by hand, no special tool needed
  • Deflective disc valve for precise damping control
  • Progressive rate spring with 90/130 spring rate (lbs/in)
  • High-pressure gas charged for consistent performance
  • Black anodized finish

These shocks are Standard Duty for Touring models, and Heavy Duty for all other models listed. Every 444 shock is hand-built, tuned and dyno'd and includes a Limited Lifetime Warranty. Sold individually.

Needed what I wanted. Very easy checkout!

Good description of parts. Now to hope what I get fits.

Easy to find product and to check out.

Easy so far

I received the product before I got the tracking information. Luckily, I live in a house, with neighbors far from me. Most customers would like tracking at the time of shipping. Only to ensure expectations and accommodations can be made if they do not own a home. I only raise this issue up as I can see foreseen issues with stolen packages. Your equipment is high quality and has high value. Thank you very much.

Thanks for making it easy to find and order what I need.
