Breathe new life into your Honda TRX400EX with this complete performance valve upgrade kit from the pros at Kibblewhite.

Key Features:
  • Oversized 34mm intake and 30mm exhaust valves for improved airflow and power
  • Durable one-piece stainless steel Black Diamond valves
  • Complete set includes intake and exhaust valves, valve springs, retainers, seals - everything you need
  • Direct OEM replacement designed specifically for 1999-2008 Honda TRX400EX models
  • Significant power gains across the RPM range compared to stock valves

This complete valve kit from Kibblewhite gives your TRX400EX dramatically improved performance and throttle response. The oversized valves allow more air into the engine for better breathing, while the stiffer valve springs ensure reliable high-RPM operation. The result is a hard-hitting powerband with stronger acceleration and top end pull compared to stock. Whether blasting through trails or tearing up the dunes, you'll feel the difference these performance valves make.
