Where It Sits

The published figures are 12 mm, 36 mm. Measure the old part against them before ordering. A check valve holds pressure in one direction and opens in the other; a worn one lets damping bleed away. The piston carries the shim stacks and meters the oil; its port layout is what makes an Öhlins damper behave the way it does. Jets meter fixed bleed flow and are sized in tenths of a millimetre.

Original Öhlins Part

A damper that can be rebuilt is a damper that stays on the bike; that is the whole argument for original service parts. The part number is the contract: it defines material, dimension and finish together. Ask us before ordering if you are unsure: a wrong part in a pressurised unit is an expensive lesson. If you are unsure which number your unit takes, send us the model and serial number of the damper and we will look it up.

Getting the Number Right

Order under 03377-45. Where several sizes share a description, only the number separates them. Öhlins states dimension a 12 mm, dimension b 36 mm for this number, and those figures are the deciding ones. Jets meter fixed bleed flow and are sized in tenths of a millimetre. Öhlins machines its pistons so the port edges stay sharp and the flow predictable.
