DescriptionThe whole story▼

Cylinder head S46, Öhlins part number 21956-01. Öhlins machines the head so the bushing bore is concentric with the seal — otherwise the shaft wears one side.

Key Features

  • Original Öhlins service part
  • Öhlins part number 21956-01

Function

This position is identified by its number rather than by a dimension. The tube is what the whole damper is built around: everything else references its bore. The cylinder is one of the few damper parts that is genuinely wear-limited. A scored bore means lost damping, because the oil bypasses the piston rather than being forced through the shims.

Genuine Service Part

Öhlins is one of the few suspension makers that still supplies every position in the exploded view as a single part. Rebuilding to specification only works if the parts are to specification — that starts here. Service parts are supplied per piece unless the description says otherwise. The exploded drawing for your unit names the number; if you do not have it, we do.

Getting the Number Right

If the unit is already open, compare the dimensions below with the part in your hand before ordering 21956-01. Öhlins does not publish a dimension here — go by the number and the exploded view. Öhlins turns and hones each tube to a defined roundness, because an out-of-round bore leaks past the piston. A scored bore means lost damping, because the oil bypasses the piston rather than being forced through the shims.

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.
