Function

Öhlins publishes 14 mm, 171.5 mm for 21000-12 — the dimensions are the identity of the part. Shaft straightness matters: a bent shaft drags in the seal head and destroys the seal within hours. Shaft diameter sets the displaced volume, which is why it is part of the damper's specification. Adjuster shafts run inside the main shaft on units with a rod-through adjuster.

Why the Original

Öhlins numbers every position so a workshop can order precisely what it needs, not a whole assembly. Öhlins keeps service parts available for units long after they leave the current price list. We can supply the whole position from the drawing rather than the single piece if that is easier. Send us the model and serial number of your unit and we will confirm the position before you order.

Getting the Number Right

Part number 21000-12 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. Check diameter 14 mm, length 171.5 mm against what you have removed; a close size is not the same part. A shaft is threaded at both ends: one for the piston, one for the mounting. Shaft diameter sets the volume displaced into the reservoir on every compression stroke.

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.
