Function
At 14 mm, 156 mm it fits one position only; the next size up carries a different number. A bent shaft drags in the head and destroys the seal within hours — replace, never straighten. Öhlins offers several lengths per diameter because stroke differs by model. A shaft is measured by diameter and overall length, and both are specific to the unit it belongs to.
Original Öhlins Part
Öhlins publishes dimensions for its service parts so a workshop can verify before it fits. Öhlins manufactures service parts on the same lines as production parts — there is no second quality. Service parts are supplied per piece unless the description says otherwise. For a full rebuild, the seal kit plus the wear parts is usually the sensible order.
Getting the Number Right
Part number 21001-05 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. Öhlins states diameter 14 mm, length 156 mm for this number, and those figures are the deciding ones. The damper shaft carries the piston through the oil and out through the seal head. The damper shaft carries the piston and passes through the seal head, so its surface finish decides how long the seals last.
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.
