Designed specifically for the 2023–2026 Kawasaki ZX-4RR, this kit restores factory-tight fork sealing integrity and guards against the contamination that degrades suspension performance over time.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eNOK-manufactured oil seals — a globally trusted name in high-performance sealing technology, chosen for durability and dimensional consistency\u003c\/li\u003e\n\u003cli\u003ePrecision inner diameter of 37.00 mm and outer diameter of 50.00 mm, machined to exact OEM tolerances for a leak-free fit\u003c\/li\u003e\n\u003cli\u003eDual dust caps form a physical barrier against road grit, mud and moisture reaching the fork leg surfaces\u003c\/li\u003e\n\u003cli\u003ePrevents fork oil loss that would otherwise compromise damping response and rider feedback\u003c\/li\u003e\n\u003cli\u003eExtends fork service life by maintaining the clean, oil-rich environment the damping internals depend on\u003c\/li\u003e\n\u003cli\u003ePart number FSK-003 ensures correct identification when ordering or cross-referencing with K-Tech service centres\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eBuild Quality \u0026amp; Materials\u003c\/h2\u003e\u003cp\u003eK-Tech has specified NOK seals for this kit rather than generic alternatives — a deliberate choice that reflects the brand's commitment to components that perform under sustained stress. NOK is recognised across motorsport and OEM production for the consistency of its rubber compounds and dimensional accuracy. Each oil seal in this kit is manufactured to resist the thermal cycling and pressure fluctuations inherent in hard road and track use, while the dust caps provide a close-tolerance interference fit that stays in place even after repeated fork cycles.\u003c\/p\u003e\u003ch2\u003ePerformance \u0026amp; Reliability\u003c\/h2\u003e\u003cp\u003eWorn or weeping fork seals are one of the most common causes of degraded suspension feel on any sportsbike. Once fork oil escapes past a failing seal, it contaminates the brake rotor and tyre, turning a maintenance issue into a safety concern. Replacing seals at the correct service interval with a quality kit like the FSK-003 keeps the ZX-4RR's suspension performing as Kawasaki intended — consistent spring rates, predictable damping and confident braking.\u003c\/p\u003e\u003ch2\u003eInstallation Note\u003c\/h2\u003e\u003cp\u003eFork seal replacement requires specialist tools and technical knowledge to ensure correct seating depth and avoid damage to the fork tubes. K-Tech recommends installation be carried out by an authorised K-Tech Service Centre to guarantee optimal function and safety.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cul\u003e\u003cli\u003eKawasaki ZX-4RR — 2023, 2024, 2025, 2026\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eAttribute\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003eFSK-003\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInner Diameter\u003c\/td\u003e\n\u003ctd\u003e37.00 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Diameter\u003c\/td\u003e\n\u003ctd\u003e50.00 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeal Manufacturer\u003c\/td\u003e\n\u003ctd\u003eNOK\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eContents\u003c\/td\u003e\n\u003ctd\u003e2x oil seals, 2x dust caps\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFitment\u003c\/td\u003e\n\u003ctd\u003eKawasaki ZX-4RR (2023–2026)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"K-Tech","offers":[{"title":"Default Title","offer_id":53168834347274,"sku":"FSK-003","price":151.0,"currency_code":"QAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/KappenKit_f24a734e-fe77-4aad-b388-6c36e6f383d1.png?v=1780817019","url":"https:\/\/inter-pace.com\/en-qa\/products\/k-tech-fork-oil-seal-dust-cap-kit-kawasaki-zx-4rr-fsk-003","provider":"Inter-Pace","version":"1.0","type":"link"}
