Experience a smoother, more controlled ride with the 444 Series Shocks. 🔧 These shocks automatically adapt to road inputs using Frequency Sensing Technology to deliver superior damping and a more composed feel over varied terrain. 🚀

Key benefits:

• Frequency Sensing Technology (FST) senses bump frequency and automatically adjusts damping for improved ride quality.
• Deflective disc valving for consistent control through varying inputs.
• Hand-adjustable pre-load spring—no special tools required.
• Includes progressive-rate spring and is high-pressure gas charged for consistent performance.
• Made in the USA.
• Length changes from stock may affect head angle and steering: slightly longer can quicken steering; slightly shorter can slow steering. Verify wheel travel and clearances before installing non-OEM lengths to avoid swingarm, axle, exhaust, chain/belt guard, or tire contact.
• Recommended for heavy duty use when the bike operates near maximum load over extended periods.
