Function
Dimensionally this is 47.3 mm, 30 mm, which is how it is told apart from the rest of the range. Öhlins recommends replacing seals whenever the unit is opened, not only when it leaks. Seal kits gather the pieces one rebuild needs, which avoids a second order mid-job. Seals are the part of a damper that decides whether it holds its gas charge and its oil, and they are the usual reason a unit ends up on the bench.
Original Öhlins Part
Öhlins supports its suspension with individual service parts, which is why a fifteen-year-old damper can still be rebuilt to specification. The part is identical to what Öhlins fits in production — same supplier, same specification. The Öhlins exploded view names the number for each position; we can look it up if you do not have it. Service parts are supplied per piece unless the description says otherwise.
Identifying the Right Part
If the unit is already open, compare the dimensions below with the part in your hand before ordering 15551-06. The published dimensions are inner diameter 47.3 mm, outer diameter 30 mm — measure the old part against them if you are unsure. An oil seal that has hardened lets the shaft pass oil past it, and the damping fades long before the leak becomes visible. Seals are the part of a damper that decides whether it holds its gas charge and its oil, and they are the usual reason a unit ends up on the bench.
Fitting and Setup Service
A damper rebuild is workshop work: it needs the unit dismantled, the shim stack rebuilt in the correct order and the gas charge reset. We are an authorised Öhlins service centre and do exactly that in house — send us the unit or ask us to fit the part with your order.
