DescriptionThe whole story▼

Öhlins lists part number HD 816 for one machine: the Harley Davidson DYNA WIDE GLIDE FXDWG built 2009–2017. A factory shock is set for an average rider on an average road, and few riders are either.

Key Features

  • 325 +5/-5 mm between mounting eyes
  • Monotube damper layout
  • Adjustable overall length for ride-height and geometry changes
  • Gas-pressurised monotube damper with the reservoir integrated into the body
  • Adjustable rebound damping via the knob above the lower eyelet
  • Fitted spring: Öhlins 21180-01
  • 36 mm damping piston
  • Öhlins fits a 32 N/mm spring to this application

The STX 36 Twin in Detail

The STX 36 Twin is built as a pair for exactly this geometry, with a 36 mm piston in a monotube body. Twin-shock installations load each damper differently from a monoshock, and Öhlins specifies the pair accordingly. Preload is set by a threaded collar on each side, and both sides must be set equally.

Damping and Adjustment

67 mm is the stroke Öhlins specifies against the DYNA WIDE GLIDE FXDWG's ratio. The fitted spring is 21180-01, and Öhlins lists neighbouring rates under their own numbers. The fitted spring rate is 32 N/mm, chosen against the DYNA WIDE GLIDE FXDWG's weight distribution rather than a catalogue average. 325 +5/-5 mm of adjustment turns ride height into a setting rather than a fixed dimension. The two adjusters do genuinely separate jobs, which is what makes methodical setup possible. Öhlins publishes a baseline setting for each part number, which is the sensible starting point.

Setting It Up for the DYNA WIDE GLIDE FXDWG

This part number spans model years 2009 to 2017; earlier and later generations take different numbers. A cruiser is often ridden two-up with luggage, which is the load case the standard suspension rarely handles well.

How Öhlins Builds It

The Öhlins part number is stamped on the unit, so its specification can be looked up years later. Every unit is dyno-tested against the curve held for its part number, not sampled from a batch. Anodising is hard-coat rather than decorative, which matters on a component exposed to road salt and stone chips.

Fitment and Compatibility

Öhlins part number HD 816 is the correct number for the Harley Davidson DYNA WIDE GLIDE FXDWG as built 2009–2017. Öhlins lists no other machine against this number, so it is not a unit that can be adapted to a neighbouring model.

Road Approval

Road approval: ABE (Germany). The unit is covered by a German ABE for the Harley Davidson DYNA WIDE GLIDE FXDWG, so no individual inspection or entry in the vehicle documents is required. The approval document ships with the product.
