Progressive Suspension 444 Series Shocks

• After more than a decade of ruling the roads with their famous 440 Series shocks with IAS, Progressive Suspension has unveiled another breakthrough design

• It is dubbed Frequency Sensing Technology (FST) for its unique ability to dynamically adjust damping as you ride

• Frequency Sensing Technology allows the shocks to sense the frequency of a bump and automatically adjust damping for superior ride quality

• These shocks also feature deflective disc valving, hand adjustable spring pre-load (no special tools needed), and progressive rate springs

• High pressure gas charged for consistent performance

• Sold in pairs

• Lifetime Limited Warranty and are Made in USA

Excellent product. Looks great with the 'all black' look being created on a bike with the HD 1/4 mile paint job...
