Function

This one measures 46 mm, 186 mm, and those figures are what separate it from the neighbouring numbers. The cylinder is one of the few damper parts that is genuinely wear-limited. Diameter and length together identify the tube — both are specific to the damper it came from. Surface finish is specified in microns, because it decides how quickly the piston band wears.

Original Öhlins Part

Suspension is one of the few areas where the original part is genuinely the cheaper decision. Parts remain available years after a unit leaves the current price list, which is unusual in this trade. Ask us before ordering if you are unsure: a wrong part in a pressurised unit is an expensive lesson. The exploded drawing for your unit names the number; if you do not have it, we do.

Identifying the Right Part

Öhlins identifies this position by the number 04210-30 in the exploded view for the unit it belongs to. Öhlins states diameter 46 mm, length 186 mm for this number, and those figures are the deciding ones. Aluminium tubes are hard-anodised in the bore so the piston band has a hard surface to run against. The cylinder tube is the working bore: the piston runs inside it and every damping force is reacted by its wall.

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.
