Where It Sits
At 12 mm, 26 mm, 3.5 mm it fits one position only; the next size up carries a different number. Circlips are single-use in practice: once sprung, they no longer hold their groove reliably. Öhlins lists these individually because a service usually needs a handful of them. Retaining rings come in a groove-specific thickness — the next size does not hold.
Why the Original
Öhlins supports its suspension with individual service parts, which is why a fifteen-year-old damper can still be rebuilt to specification. Öhlins is one of the few suspension makers that still supplies every position in the exploded view as a single part. Order by part number — descriptions repeat across sizes, numbers do not. We can supply the whole position from the drawing rather than the single piece if that is easier.
How to Be Sure It Fits
15554-01 is the Öhlins number for this position — the same one printed in the service documentation. The published dimensions are dimension a 12 mm, dimension b 26 mm, dimension c 3.5 mm — measure the old part against them if you are unsure. Öhlins lists washers by thickness because it forms part of the internal stack height. Öhlins lists these individually because a service usually needs a handful of them.
Fitting and Setup Service
We are an authorised Öhlins service centre, so you do not have to source the tools and the nitrogen: send us the damper and we rebuild it with the correct parts and the correct setting.
