Where It Sits
This one measures 8 mm, 384 mm, and those figures are what separate it from the neighbouring numbers. Shaft diameter sets the displaced volume, which is why it is part of the damper's specification. Corrosion on a stored damper usually starts on the exposed shaft. A bent shaft drags in the head and destroys the seal within hours — replace, never straighten.
Original Öhlins Part
Parts remain available years after a unit leaves the current price list, which is unusual in this trade. This is an original Öhlins part, not an aftermarket equivalent — the tolerances are the ones the unit was assembled to. Order by part number — descriptions repeat across sizes, numbers do not. Order by part number. The dimensions below are the ones Öhlins publishes for it.
Identifying the Right Part
Order under 21812-11. Where several sizes share a description, only the number separates them. Check diameter 8 mm, length 384 mm against what you have removed; a close size is not the same part. Any mark on the polished section is a reason to replace rather than to reassemble. Corrosion on a stored damper usually starts on the exposed shaft.
Fitting and Setup Service
Fitting service parts means opening a pressurised unit. As an authorised Öhlins service centre we do that here, with the right tools and a dyno check afterwards — just ask.
