DescriptionThe whole story▼
Spring valve rod 52 N, Öhlins part number 15840-01. A worn valve bleeds damping away without any visible symptom.
Key Features
- Öhlins part number 15840-01
- Original Öhlins service part
What It Is
Öhlins publishes no separate dimension for this position, so the part number carries the identity. Valves hold pressure in one direction and open in the other. Port area sets how much oil can pass before the shims begin to lift. Replacing a piston is a workshop job because the shim stack has to be rebuilt in the correct order.
Genuine Service Part
Öhlins manufactures service parts on the same lines as production parts — there is no second quality. The alternative to a service part is usually a new damper, which is why this catalogue exists. Service parts are ordered per piece unless stated otherwise. If you are between two sizes, send us the measurement and we will check it against the catalogue.
Identifying the Right Part
Order under 15840-01. Where several sizes share a description, only the number separates them. This position has no published dimension, so the part number is the only reliable identifier. Piston bands are consumables — they wear against the bore and lose their seal gradually. The piston carries the shim stacks and meters the oil; its port layout is what makes an Öhlins damper behave the way it does.
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.
