Throttle Kickdown Cable GM/Chevy TH350 56in

The Throttle Kickdown Cable GM/Chevy TH350 56in is a carburetor-mounted throttle linkage component engineered for classic and vintage marine engines using General Motors TH350 automatic transmissions. Built for boaters and engine builders who demand reliable downshift timing and throttle responsiveness, this 56-inch kickdown cable ensures your transmission receives proper signal feedback when you demand power from your inboard or outboard powerplant. Correct kickdown cable function is essential—without it, your TH350 will shift late, bog under acceleration, and waste fuel, leaving you underpowered when you need it most on the water.

This throttle kickdown cable features a braided stainless steel housing that resists corrosion and salt spray—critical for marine environments where standard cables fail within seasons. The aluminum fittings provide lightweight durability while the natural finish resists oxidation better than bare steel. At 56 inches in overall length, this cable suits most mid-range console and cabin cruiser installations where the carburetor sits moderate distance from the transmission control lever. The kickdown mechanism works by translating throttle position directly to transmission line pressure; as you advance the throttle, the cable pulls the kickdown valve open, commanding earlier downshifts and preventing the transmission from hunting between gears during acceleration or load changes.

This cable is purpose-built for TH350-equipped marine and automotive applications where carburetor throttle control directly manages transmission behavior. Whether you're restoring a classic ski boat, rebuilding a vintage cabin cruiser engine bay, or upgrading a performance rebuild, proper cable routing and adjustment are non-negotiable—slack or binding causes hesitation and transmission lag. The kit format includes all necessary hardware for straightforward installation; measure carefully from carburetor mounting point to transmission kickdown lever before ordering, as cable length is fixed and must match your specific engine and transom configuration.
