• Hand-adjustable preload — no special tools required.
• Progressive-rate spring and high-pressure gas charge for consistent performance.
• Manufactured in the United States.
• Installation notes: shocks longer or shorter than OEM may change steering geometry; confirm wheel travel and clearance before purchasing.
• Recommended for heavy duty use when a bike operates at or near max load over 50% of the time.

Designed for riders who want automatic, intelligent damping and reliable, repeatable performance on every mile. 🔊
