– 444 Series Shocks — 12.50″ – Black – Standard/Heavy-Duty – 12.5″
77 Cycles is a proud supporter of PROGRESSIVE SUSPENSION and Harley-Davidson.
- Feature the all-new Frequency Sensing Technology (FST) which allows the shocks to sense the frequency of a bump and automatically adjust damping for superior ride quality
- Deflective disc valving
- Adjust spring pre-load by hand, no special tool needed
- Include a progressive-rate spring and are high-pressure gas charged for consistent performance
- Shocks slightly longer than stock may alter head angle slightly and provide quicker steering.
- Shocks slightly shorter than stock may alter head angle and provide slower steering.
- Before purchasing or attempting to install shocks different than OEM length, confirm your wheel travel can be altered without causing clearance issues, such as swingarm/axle to exhaust contact and chain/belt guard or tire contact.
- Heavy duty applications recommended for bikes operating at or near maximum load rating over 50% of the time.
