Kawasaki KSF400 KFX400 Suzuki LTZ400 Arctic Cat DVX400 Intake Exhaust Valve OEM #12004-S004 Choose (Sold Each)

OVERVIEW

This intake and exhaust valve set replaces worn or damaged engine valves directly, restoring proper combustion sealing and compression. The components are constructed from durable, heat-resistant steel alloys designed for reliable long-term operation. They are engineered as direct OEM-style replacements for select Kawasaki, Suzuki, and Arctic Cat ATVs.

ENGINEERING & PERFORMANCE

Precision-machined from SUH35B heat-resistant stainless steel, these valves maintain structural integrity under extreme cylinder head temperatures. The available nitride surface treatment significantly increases corrosion resistance and reduces stem friction during high-RPM operation. Performance versions feature a swirl polish stem and Stellite-Tipped stems to further enhance durability and sealing stability. All valves are manufactured to exacting OEM dimensions, ensuring accurate installation and consistent engine performance upon rebuild.
