Pins and dowels locate parts to each other; without them the assembly is merely clamped, not positioned. Öhlins uses metric threads throughout, but the length and head form are specific to the position. Its length is a specification, not a filler — a millimetre changes what the unit does.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eParts remain available years after a unit leaves the current price list, which is unusual in this trade. Öhlins supports its suspension with individual service parts, which is why a fifteen-year-old damper can still be rebuilt to specification. 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. If the unit is already apart, compare the published dimensions with the part in your hand.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eThe reliable route is the exploded drawing: find the position, read the number, order it — 21974-02 in this case. dimension a 18 mm, dimension b 31.8 mm, dimension c 3 mm is what distinguishes this number from its neighbours in the range. Circlips hold axial position under load; a sprung one lets the assembly walk. A spacer sets an internal dimension: preload on a stack, free length, or the position of a piston.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eIf you would rather not open the damper yourself, we can do it — we are an authorised Öhlins service centre and rebuild these units as a matter of routine.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cem\u003eBrand:\u003c\/em\u003e Öhlins\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003ePart Number:\u003c\/em\u003e 21974-02\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Spacers\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension A:\u003c\/em\u003e 18 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 31.8 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension C:\u003c\/em\u003e 3 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCountry of Origin:\u003c\/em\u003e Sweden\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Öhlins","offers":[{"title":"Default Title","offer_id":53653155021066,"sku":"21974-02","price":6921.15,"currency_code":"ARS","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21974-02_903433f6-a809-4cc3-adb6-4a35a58e06ee.png?v=1788880587","url":"https:\/\/inter-pace.com\/en-ar\/products\/ohlins-spacer-18-31-8-3-21974-02","provider":"Inter-Pace","version":"1.0","type":"link"}
