KONG Billet Extreme Duty Bypass Tube for Mercury Racing 450R/500R *Lifetime Guarantee*

KONG Billet Extreme Duty Bypass Tube for Mercury Racing 450R/500R The factory bypass tube found on Mercury Racing 450R and 500R engines has a known weak point where the plastic tube connects to the bypass valve. Over time, this connection can crack or split from the pressure, heat, vibration, and stress experienced in high-performance marine applications. The KONG Extreme Duty Bypass Tube completely eliminates the failure-prone plastic construction by replacing the entire tube with a precision-machined billet aluminum assembly built for maximum strength and durability. Unlike the factory plastic component, our billet design is engineered to withstand extreme pressure, heat, vibration, and stress without cracking, splitting, or failing. Whether your 450R/500R is stock or modified, this is a simple reliability upgrade designed to eliminate a known weak point before it becomes a problem. Key Features: 💪 Full billet aluminum construction with hard anodizing 🛠️ Eliminates the failure prone OEM plastic bypass tube 💨 Designed to withstand extreme pressure, heat, and stress ⚡ Direct bolt on replacement for the factory tube 🚤 Fits Mercury Racing 450R & 500R engines 🏆 LIFETIME GUARANTEE
