Back to TRX400EX Valve Kits

No more ticking!

My 400ex has never sounded better. New tensioner, guides, and chain fixed the noise. Metal bottom end gasket was cool too, didn't rip while working on it.

Thank you for your positive review! We're glad to hear that the TRX400EX Cam Chain Tensioner & Wiseco Heavy Duty Cam Chain Kit was able to fix the ticking noise on your 400ex. We agree, these small maintenance steps can make a big difference in the overall performance and sound of your vehicle. We appreciate your feedback and hope to continue providing quality products for your ATV. Happy riding!
