PROGRESSIVE SUSPENSION 444 Series Shocks — 330 mm (13.00"), Rear, Chrome – 91-17 Dyna, 01-02, 07-10 CVO

The 444 Series Shocks deliver refined ride control with the all-new Frequency Sensing Technology (FST). FST senses the frequency of a bump and automatically adjusts damping for superior ride quality, pairing deflective disc valving with a progressive-rate spring for consistent performance. 🚀

Pre-load spring adjusts by hand with no special tool needed, and the high-pressure gas charge helps maintain consistent damping through changing conditions. Before purchasing or attempting installation, confirm your wheel travel can be altered without causing clearance issues such as swingarm or axle contact with the exhaust, and chain/belt guard or tire contact. ⚠️

Shocks slightly longer than stock may alter head angle and provide quicker steering, while shocks slightly shorter than stock may slow steering. Heavy duty applications are recommended for bikes operating at or near maximum load rating over 50% of the time.

Made in the USA. Proceed with installation only after verifying clearance and fitment to avoid interference with swingarm, axle, tire, or exhaust. 🔧
