444 Series Shocks

Experience superior ride quality with the all-new Frequency Sensing Technology (FST), which senses the frequency of a bump and automatically adjusts damping for a smoother, more controlled ride. 🚀

Deflective disc valving combines with a hand-adjustable preload spring—no special tools required—to give reliable, tunable performance. These shocks include a progressive-rate spring and are high-pressure gas charged to maintain consistent feel under varying loads.

• Made in the USA
• Shocks slightly longer or shorter than stock may alter head angle and change steering response; confirm wheel travel and clearance before installation
• Recommended for heavy duty applications when operating near maximum load more than half the time

Built for riders who want improved compliance and control without sacrificing durability. 🔧
