Öhlins gives the tube its diameter and its working length as a pair — a tube of the same bore but different length belongs to a different unit.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eLength 171 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 04211-29\u003c\/li\u003e\n\u003cli\u003eDiameter 46 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhere It Sits\u003c\/h2\u003e\u003cp\u003eThe published figures are 46 mm, 171 mm. Measure the old part against them before ordering. The cylinder tube is the working bore of the damper: the piston runs in it, and its finish decides how well the piston rings seal. The tube also carries the end cap threads, so thread damage means a new tube. Öhlins hones its tubes to a defined surface finish rather than simply to a diameter.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eThe part number is the contract: it defines material, dimension and finish together. The tolerances here are the ones the unit was assembled to, not a pattern equivalent's interpretation of them. The Öhlins exploded view names the number for each position; we can look it up if you do not have it. Order by part number. The dimensions below are the ones Öhlins publishes for it.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003eIf the unit is already open, compare the dimensions below with the part in your hand before ordering 04211-29. Check diameter 46 mm, length 171 mm against what you have removed; a close size is not the same part. Bore finish decides how well the piston band seals; a scored tube leaks damping past the piston. A scored bore means lost damping, because the oil bypasses the piston rather than being forced through the shims.\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 04211-29\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Cylinder Tubes\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDiameter:\u003c\/em\u003e 46 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eLength:\u003c\/em\u003e 171 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":53649373856010,"sku":"04211-29","price":105.23,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/04211-29_6a5e211e-19e3-4732-abc3-bf8f4f91a56a.png?v=1788875112","url":"https:\/\/inter-pace.com\/products\/ohlins-cylinder-tube-46-171-al-04211-29","provider":"Inter-Pace","version":"1.0","type":"link"}
