ProX 40.S496011 2000-2020 Suzuki DR-Z400 DR-Z400S DR-Z400E Fork Seal Kit — Stops Leaks & Restores Smooth Suspension

ProX — Preventing Oil Leaks and Protecting Fork Internals, Stop letting oil-soaked brake pads and soft suspension ruin your ride.

Leaking fork seals are more than just a mess; they are a safety hazard that can contaminate your front brake system and cause inconsistent front-end handling. When your Suzuki DR-Z400 starts weeping oil down the fork legs, it's a sign that dirt and debris have compromised the seal. Replacing them with this ProX kit ensures your suspension stays pressurized and your fork oil stays exactly where it belongs.

Manufactured in Japan by NOK, the same supplier used by leading motorcycle brands, these seals offer Factory Quality performance without the premium price tag. Each kit features a high-grade rubber compound designed to withstand the friction and heat of off-road riding, while the included dust wipes provide a secondary barrier against the Florida sand and mud that lead to premature seal failure.

• Produced by NOK Japan to ensure Factory Quality fitment and long-term durability.
• Includes two high-performance fork seals and two heavy-duty dust wipes for a full rebuild.
• Exact dimensional tolerances ensure a leak-free fit on Suzuki DR-Z400 49mm conventional forks.
• Low-friction design improves "stiction" for smoother suspension movement and better tracking.
• Advanced rubber compounds resist chemical breakdown from synthetic and mineral fork oils.

Moto-House MX Pro Tip:

Before installing your new ProX seals, always inspect your Suzuki DR-Z400 inner fork tubes for any tiny nicks or rock chips. Even a Factory Quality seal will leak if the chrome surface is damaged. Use a very fine 2000-grit wet sandpaper to gently smooth out any burrs, and always use a fork seal bullet or plastic wrap over the end of the fork tube to prevent the sharp edges from slicing the new seal during installation.
