The piston carries the shim stacks and meters the oil; its port layout is what makes an Öhlins damper behave the way it does.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eÖhlins part number 01021-03\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat It Is\u003c\/h2\u003e\u003cp\u003eThere is no measurement to check here — the number and the exploded view identify it. The seat face has to be flat enough for the first shim to seal against it. A scored piston face means oil bypasses the shims entirely. A worn piston band lets oil past the outside of the piston, which shows up as damping that has gone soft.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eThe part number is the contract: it defines material, dimension and finish together. Suspension is one of the few areas where the original part is genuinely the cheaper decision. Service parts are supplied per piece unless the description says otherwise. Order by part number — descriptions repeat across sizes, numbers do not.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eOrder under 01021-03. Where several sizes share a description, only the number separates them. Where no measurement is given, the drawing position is what identifies the part. Öhlins machines the ports rather than casting them, so the edges stay sharp and the flow predictable. 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\u003eFitting service parts means opening a pressurised unit. As an authorised Öhlins service centre we do that here, with the right tools and a dyno check afterwards — just ask.\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 01021-03\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Jets\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":53648988340490,"sku":"01021-03","price":5300.0,"currency_code":"XAF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/01021-03_ebb045a2-74f0-4c10-9a86-b42f6b1d2a5b.png?v=1788872906","url":"https:\/\/inter-pace.com\/en-cg\/products\/ohlins-shaft-jet-bleed-4-0-01021-03","provider":"Inter-Pace","version":"1.0","type":"link"}
