DescriptionThe whole story▼

Cylinder head TTX36, Öhlins part number 21879-01. Diameter and length together identify the tube — both are specific to the damper it came from.

Key Features

  • Öhlins part number 21879-01
  • Original Öhlins service part

Function

This position is identified by its number rather than by a dimension. Corrosion inside a tube is terminal: it cannot be honed out without changing the clearance. Most seal kits are built around a specific head design. The cylinder is one of the few damper parts that is genuinely wear-limited.

Genuine Service Part

Öhlins supports units that are decades old, which is why the spare parts list runs to thousands of numbers. Öhlins lists this part under its own number in the service catalogue so a workshop can order exactly what it needs. We can check the number against the Öhlins exploded view before you order — just ask. Öhlins numbers do not follow a logic you can guess — always read them from the documentation.

How to Be Sure It Fits

Order under 21879-01. 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. The cylinder tube is the working bore of the damper: the piston runs in it, and its finish decides how well the piston rings seal. Öhlins matches tube and piston as a pair during assembly, which is why the part numbers are specific.

Fitting and Setup Service

Fitting service parts means opening a pressurised unit. As an authorised Öhlins service centre we do that here, with the right tools and a dyno check afterwards — just ask.
