DescriptionThe whole story▼

Valve seat shim TT44 Mk2, Öhlins part number 05849-01. Öhlins machines its pistons rather than sintering them, which is why the port edges stay sharp.

Key Features

  • Öhlins part number 05849-01
  • Original Öhlins service part

Function

There is no measurement to check here — the number and the exploded view identify it. Port area and shim seat geometry decide the damping curve before any adjuster is touched. Rebuilding a piston means keeping the shim order, because the stack is the tuning. A worn valve bleeds damping away without any visible symptom.

Genuine Service Part

Öhlins supports its suspension with individual service parts, which is why a fifteen-year-old damper can still be rebuilt to specification. Suspension is one of the few areas where the original part is genuinely the cheaper decision. The exploded drawing for your unit names the number; if you do not have it, we do. Order by part number — descriptions repeat across sizes, numbers do not.

Getting the Number Right

The reliable route is the exploded drawing: find the position, read the number, order it — 05849-01 in this case. Öhlins does not publish a dimension here — go by the number and the exploded view. Port area sets how much oil can pass before the shims begin to lift. Valves hold pressure in one direction and open in the other.

Fitting and Setup Service

Ask us about a full service: as an authorised Öhlins centre we strip, inspect, replace what is worn and set the unit back to its specification.
