Stop washers limit travel of an internal part and are sized to that job. Retaining rings come in a groove-specific thickness — the next size does not hold. Ordering the small parts with the seal kit saves the second delivery that most rebuilds otherwise need.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eThis is an original Öhlins part, not an aftermarket equivalent — the tolerances are the ones the unit was assembled to. A damper that can be rebuilt is a damper that stays on the bike; that is the whole argument for original service parts. If the unit is already apart, compare the published dimensions with the part in your hand. If you are between two sizes, send us the measurement and we will check it against the catalogue.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eIf the unit is already open, compare the dimensions below with the part in your hand before ordering 21617-15. Check dimension a 8.2 mm, dimension b 20 mm, dimension c 4 mm against what you have removed; a close size is not the same part. Stainless where corrosion matters, hardened where load matters — the choice is made per position. Washers spread load and set clearance; in a damper both of those are specifications.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eA damper rebuild is workshop work: it needs the unit dismantled, the shim stack rebuilt in the correct order and the gas charge reset. We are an authorised Öhlins service centre and do exactly that in house — send us the unit or ask us to fit the part with your order.\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 21617-15\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Washers\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension A:\u003c\/em\u003e 8.2 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 20 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension C:\u003c\/em\u003e 4 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":53652602847498,"sku":"21617-15","price":8.16,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21617-15_4f61a93e-690f-41e5-9be7-72f8c54471d4.png?v=1788879657","url":"https:\/\/inter-pace.com\/products\/ohlins-washer-8-2-20-4-21617-15","provider":"Inter-Pace","version":"1.0","type":"link"}
