What It Is

16 mm, 238 mm: that is the whole specification, and it has to match what came out. Corrosion on a stored damper usually starts on the exposed shaft. The damper shaft carries the piston and passes through the seal head, so its surface finish decides how long the seals last. Any mark on the polished section is a reason to replace rather than to reassemble.

Genuine Service Part

Buying the individual part rather than a complete assembly is what makes servicing an Öhlins unit worthwhile. Öhlins supports units that are decades old, which is why the spare parts list runs to thousands of numbers. Öhlins parts are unit-specific: a close dimension is not a substitute. If you are unsure which number your unit takes, send us the model and serial number of the damper and we will look it up.

Getting the Number Right

Öhlins identifies this position by the number 05508-09 in the exploded view for the unit it belongs to. Öhlins states diameter 16 mm, length 238 mm for this number, and those figures are the deciding ones. Surface hardness is what lets the shaft survive thousands of cycles through a seal. The damper shaft carries the piston through the oil and out through the seal head.

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.
