About the STX 36 Twin Range

Öhlins offers several body and spring finishes in this range because the shocks are visible on the machines that use them. The STX 36 Twin is built as a pair for exactly this geometry, with a 36 mm piston in a monotube body. Twin-shock machines share the load between two units, and that changes everything about how each one is specified: half the load, but also half the leverage and often a steeper mounting angle.

Fitted to the DYNA WIDE GLIDE FXDWG

A cruiser is often ridden two-up with luggage, which is the load case the standard suspension rarely handles well. Öhlins covers the 8-year production run of this generation with a single part number, which means the mounting and the linkage stayed unchanged across it.

Damping and Adjustment

Öhlins builds it to 305 mm between the eyes for this chassis. 61 mm of stroke is what the DYNA WIDE GLIDE FXDWG's linkage allows, and the shim stack is set for exactly that. Spring part number 21180-01 is a separate catalogue item, so a rate change is inexpensive. A 36 mm piston gives the oil a large working area, so the force curve stays flat as temperature rises. A single click produces a change most riders can detect, which is not true of every adjustable damper. Öhlins publishes a baseline setting for each part number, which is the sensible starting point.

Construction and Material Quality

Machining, anodising, assembly and testing all happen in the same building rather than across a supply chain. The damper body is hard-anodised aluminium, which resists both corrosion and the thermal cycling a rear shock lives with. 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 817 is the correct number for the Harley Davidson DYNA WIDE GLIDE FXDWG as built 2009–2016. It is model-specific rather than universal: length, stroke and valving are all set for this chassis.

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.
