Replacing a piston is a workshop job because the shim stack has to be rebuilt in the correct order. Rebuilding a piston means keeping the shim order, because the stack is the tuning. Port area sets how much oil can pass before the shims begin to lift.\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 lists this part under its own number in the service catalogue so a workshop can order exactly what it needs. The exploded drawing for your unit names the number; if you do not have it, we do. 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\u003ePart number 15441-06 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. The published dimensions are dimension a 29.0 mm, dimension b 16.4 mm, dimension c 4.6 mm — measure the old part against them if you are unsure. Rebuilding a piston means keeping the shim order, because the stack is the tuning. 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\u003eWe 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.\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 15441-06\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 29.0 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 16.4 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension C:\u003c\/em\u003e 4.6 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":53649729093898,"sku":"15441-06","price":24.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/15441-06_87dd5640-101c-4892-9601-38426438404c.png?v=1788876381","url":"https:\/\/inter-pace.com\/en-pa\/products\/ohlins-hydraulic-stop-piston-29-0-16-4-4-6-15441-06","provider":"Inter-Pace","version":"1.0","type":"link"}
