DescriptionThe whole story▼

Shaft 8/508.5, Öhlins part number 15404-01. A shaft is threaded at both ends: one for the piston, one for the mounting.

Key Features

  • Öhlins part number 15404-01
  • Length 508.5 mm
  • Diameter 8 mm
  • Original Öhlins service part

Function

8 mm, 508.5 mm: that is the whole specification, and it has to match what came out. The polished section runs in the seal; a mark there ends the seal's life. A bent shaft drags in the head and destroys the seal within hours — replace, never straighten. The shaft is threaded at both ends: piston at one, mounting at the other.

Original Öhlins Part

Öhlins publishes dimensions for its service parts so a workshop can verify before it fits. The part number is the contract: it defines material, dimension and finish together. The exploded drawing for your unit names the number; if you do not have it, we do. Öhlins parts are unit-specific: a close dimension is not a substitute.

Identifying the Right Part

Part number 15404-01 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. diameter 8 mm, length 508.5 mm is what distinguishes this number from its neighbours in the range. Shaft diameter sets the volume displaced into the reservoir on every compression stroke. A shaft is threaded at both ends: one for the piston, one for the mounting.

Fitting and Setup Service

If you would rather not open the damper yourself, we can do it — we are an authorised Öhlins service centre and rebuild these units as a matter of routine.
