DescriptionThe whole story▼
Lock ring, Öhlins part number 21825-01. Circlips are single-use in practice: once opened, the grip is no longer reliable.
Key Features
- Original Öhlins service part
- Öhlins part number 21825-01
Function
This position is identified by its number rather than by a dimension. Öhlins publishes them in the exploded view so a workshop can order the whole position at once. Spacers set the internal geometry of the unit, which means their length is a specification and not a filler. Ordering the small parts with the seal kit saves the second delivery that most rebuilds otherwise need.
Genuine Service Part
This is an original Öhlins part, not an aftermarket equivalent — the tolerances are the ones the unit was assembled to. Öhlins keeps service parts available for units long after they leave the current price list. Ask us before ordering if you are unsure: a wrong part in a pressurised unit is an expensive lesson. Service parts are supplied per piece unless the description says otherwise.
How to Be Sure It Fits
21825-01 is the Öhlins number for this position — the same one printed in the service documentation. This position has no published dimension, so the part number is the only reliable identifier. Small parts are what hold a rebuild together — the wrong circlip or washer is enough to fail the job. These are the parts that are easy to lose on the bench and impossible to improvise afterwards.
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.
