Progressive Suspension 444 Series Shocks — 330 mm (13.00") length, Black

444 Series shocks deliver refined ride control using Frequency Sensing Technology (FST), which senses bump frequency and automatically adjusts damping for superior ride quality.

Key features:

• Deflective disc valving for consistent damping
• Pre-load spring adjusts by hand with no special tool needed
• Includes a progressive-rate spring and is high-pressure gas charged for consistent performance
• Made in the USA

Installation notes: shocks slightly longer or shorter than stock may alter head angle and change steering response. Before purchasing or attempting installation of shocks different than OEM length, confirm wheel travel and clearances to avoid swingarm/axle to exhaust contact or chain/belt guard or tire contact.
