Whether you ride the ZX-4RR daily or push it hard on track days, these seals deliver the consistent, long-lasting protection your suspension deserves.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eManufactured by NOK in collaboration with SHOWA — the same engineers behind the original fork specification on the ZX-4RR.\u003c\/li\u003e\n\u003cli\u003eDirect OEM replacement with exact dimensions (37.00 mm inner diameter, 50.00 mm outer diameter, 11.00 mm height) for a precise, gap-free fit.\u003c\/li\u003e\n\u003cli\u003ePrevents oil loss and contamination that would otherwise compromise fork damping and suspension response.\u003c\/li\u003e\n\u003cli\u003eKit includes two oil seals — everything you need to service both fork legs in a single purchase.\u003c\/li\u003e\n\u003cli\u003eKeeps suspension internals protected against dirt, moisture and premature wear for extended service life.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSHOWA\/NOK Quality You Can Rely On\u003c\/h2\u003e\u003cp\u003eK-Tech has built its reputation on sourcing and developing suspension components that match or exceed factory standards. The FSS-003 seals are produced by NOK — one of the world's leading seal manufacturers — under a specification refined alongside SHOWA to suit the precise fork geometry of the ZX-4RR. The result is a seal that seats cleanly, resists blow-by under hard braking and compression loads, and maintains its integrity across a wide temperature range.\u003c\/p\u003e\u003ch2\u003eSuspension Performance, Maintained\u003c\/h2\u003e\u003cp\u003eA weeping fork seal does more than leave an oil smear on your stanchion — it progressively ruins damper feel, deposits oil on the brake disc, and allows abrasive contamination to enter the fork internals. Replacing worn seals with the K-Tech FSS-003 kit restores the fork to the precise action the ZX-4RR was designed to deliver. The 37 mm bore dimension fits the SHOWA fork fitted as standard to the 2023–2026 ZX-4RR, and the 50 mm outer diameter ensures a reliable housing fit with no movement or fretting.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThis kit is specifically designed for the following application:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eKawasaki ZX-4RR — model years 2023, 2024, 2025 and 2026\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eInstallation requires specialist tools and technical knowledge of suspension servicing.
