Replacing a piston is a workshop job because the shim stack has to be rebuilt in the correct order.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDimension B 37.9 mm\u003c\/li\u003e\n\u003cli\u003eDimension C 15 mm\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eDimension A 17.1 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 06165-01\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat It Is\u003c\/h2\u003e\u003cp\u003e06165-01 is the 17.1 mm, 37.9 mm, 15 mm version — Öhlins lists each size separately. Needle geometry sets the shape of the adjustable range, not just its size. A scored piston face means oil bypasses the shims entirely. Rebuilding a piston means keeping the shim order, because the stack is the tuning.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eParts remain available years after a unit leaves the current price list, which is unusual in this trade. Öhlins numbers every position so a workshop can order precisely what it needs, not a whole assembly. 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. Order by part number — descriptions repeat across sizes, numbers do not.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003ePart number 06165-01 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. dimension a 17.1 mm, dimension b 37.9 mm, dimension c 15 mm is what distinguishes this number from its neighbours in the range. Port area and shim seat geometry decide the damping curve before any adjuster is touched. A check valve holds pressure in one direction and opens in the other; a worn one lets damping bleed away.\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 06165-01\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Pistons\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension A:\u003c\/em\u003e 17.1 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 37.9 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension C:\u003c\/em\u003e 15 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":53649360617738,"sku":"06165-01","price":114.55,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/06165-01_3b478f5c-bad8-47ac-a546-fd211a14b8a3.png?v=1788875044","url":"https:\/\/inter-pace.com\/en-bg\/products\/ohlins-piston-17-1-37-9-15-06165-01","provider":"Inter-Pace","version":"1.0","type":"link"}
