DescriptionThe whole story▼
The K-Tech DSS-007 Dust Seals Kit is engineered to preserve the precision and longevity of your Kawasaki Ninja 400's front forks across the full 2018–2023 model run. Manufactured by NOK — a name synonymous with exacting seal technology in the motorsport and automotive industries — these dust seals combine a heritage of quality with a design purpose-built for the Ninja 400's fork geometry, delivering a drop-in fit that maintains suspension performance mile after mile.
Key Features
- Manufactured by NOK: seals produced to the exacting standards that have made NOK a trusted name in suspension components worldwide
- Precision dimensions matched to the Ninja 400 fork: 41.00 mm inner diameter and 54.40 mm outer diameter ensure a secure, rattle-free seat
- Direct OEM replacement fit — no modification or adapters required, simply swap out worn seals and ride
- Dual-height profile (4.60 mm / 14.00 mm) effectively sheds road debris, mud and moisture before it can reach the oil seals beneath
- Kit supplies both fork legs: two dust seals included, covering a complete front-fork service in a single purchase
- Extends suspension service intervals by keeping damping oil clean and fork stanchions free from abrasive contamination
Design, Finish and Heritage
K-Tech Suspension has built its reputation on components that combine race-derived engineering with road-going durability. The DSS-007 reflects that philosophy: the seals are produced by NOK using compound formulations chosen for their resistance to ozone, road chemicals and temperature cycling — the everyday adversaries of any street-ridden Ninja 400. The clean, close-tolerance profile mirrors the original factory design so the fork assembly retains its factory appearance while benefiting from a fresh, high-quality seal contact surface.
Where lesser aftermarket dust seals can introduce microscopic clearances that allow grit ingress, the DSS-007's precisely dimensioned lips wipe the stanchion cleanly on every compression and rebound stroke. The result is a fork that stays supple, responsive and leak-free for far longer between services.
Installation Notes
Installation requires the front forks to be removed and partially disassembled. K-Tech recommends that fitting is carried out by an authorised K-Tech service centre using the appropriate seal drivers and assembly tools to guarantee correct seating depth and seal integrity. Incorrect installation can compromise both performance and safety.
Fitment and Compatibility
The K-Tech DSS-007 Dust Seals Kit is designed exclusively for the following model:
- Kawasaki Ninja 400 — model years 2018, 2019, 2020, 2021, 2022 and 2023
Always verify your fork inner diameter against the 41.00 mm specification before ordering if your machine has been fitted with non-standard forks.
