Description

Your TRX400EX's exhaust valve is subjected to extreme heat cycles and high RPM stress—factory valves wear quickly under aggressive use or tuning. The Hot Cams Steel Exhaust Valve restores precision sealing and durability, ensuring consistent performance whether you're racing or riding hard. Built to OEM fitment standards with performance-grade construction, this is a straightforward bolt-on replacement that demands no modification.

The forged one-piece design and advanced coatings mean you're not just replacing a worn part—you're upgrading to a valve engineered for longevity and reliability under sustained load.

  • Forged one-piece construction
  • Nitride coated stem
  • Induction hardened tip
  • Precision machined seat
  • Polished surface finish
  • OEM keeper compatible
  • 1999–2008 TRX400EX fitment
  • MPN: 8400003-1
