SPI SM-05290 MAG Exhaust Power Valve Cable for Arctic Cat Snowmobiles

The SPI SM-05290 is a MAG-side replacement exhaust valve cable (also known as a power valve cable) designed for Arctic Cat snowmobiles. This aftermarket cable is engineered to exact OEM specifications, providing a direct, drop-in replacement for worn or damaged factory cables.

The exhaust power valve system relies on precisely routed cables to actuate the valve mechanism, which optimizes exhaust port timing across the RPM range for peak two-stroke performance. A stretched, frayed, or broken cable can result in poor throttle response, reduced power, and erratic engine behavior — making timely replacement essential.

Key Features:

• MAG-side exhaust valve (power valve) cable
• Direct OEM replacement — no modifications required
• Replaces Arctic Cat OEM part numbers 3006-473 and 3006-694
• Engineered to match original equipment fit, form, and function
• Sold individually (each)

This cable is a quality aftermarket solution from SPI (Sports Parts Inc.), a trusted supplier of snowmobile replacement parts.
