DescriptionThe whole story▼

Separating piston 44, Öhlins part number 01005-04. Port area and seat geometry decide the damping before any adjuster is touched.

Key Features

  • Original Öhlins service part
  • Öhlins part number 01005-04

What It Is

This position is identified by its number rather than by a dimension. Port area sets how much oil can pass before the shims begin to lift. The seat face has to be flat enough for the first shim to seal against it. The piston carries the shim stacks and meters the oil; its port layout is what makes an Öhlins damper behave the way it does.

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 keeps service parts available for units long after they leave the current price list. Where a number has been superseded, Öhlins states the replacement — we pass that on. Tell us the damper's model designation and year and we will match the number for you.

Getting the Number Right

Order under 01005-04. Where several sizes share a description, only the number separates them. Öhlins does not publish a dimension here — go by the number and the exploded view. Piston bands are consumables — they wear against the bore and lose their seal gradually. Port area sets how much oil can pass before the shims begin to lift.

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.
