Ohlins HD816 STX 36 Twin Rear Shock Absorbers for Harley-Davidson Dyna FXD

The Öhlins HD816 is a pair of STX 36 Twin rear shock absorbers engineered for Harley-Davidson Dyna FXD motorcycles. Built on Öhlins' proven STX platform, these shocks deliver a significant upgrade over stock suspension in both ride comfort and handling precision, offering controlled damping and consistent chassis behavior across a wide range of road conditions.

Key Features:

• STX 36 Monotube Design: High-pressure gas shock with internal reservoir (oil/gas separated) housed within the main body for consistent damping performance
• 36mm Piston: Large-diameter single-tube piston (S36DR1L type) for superior damping control and durability
• Adjustable Rebound Damping: Conveniently located adjuster wheel above the end eye allows fine-tuning of rebound characteristics to suit rider preference and road conditions
• Adjustable Spring Preload: Easily configurable for solo or two-up riding, and can be tuned to accommodate varying passenger loads
• Length Adjustable: Variable length from approximately 12.6 to 13.0 inches (320mm to 330mm) for ride height customization
• Spring Rate: 32 N/mm mounted spring for a balanced ride between comfort and support
• Stroke: 67mm of travel for effective bump absorption
• Sold as a Pair: Includes two complete rear shock absorbers
• Rebuildable: Öhlins shocks are designed to be fully serviced and rebuilt to maintain long-term performance

The HD816 improves rear-end stability under braking and acceleration while reducing chassis movement through corners. The oil/gas separated construction helps maintain damping consistency on longer rides and in varying temperature conditions. Whether riding solo or two-up, the adjustable preload and rebound settings allow riders to dial in their preferred setup with precision.
