Throttle Cable Ext. Kit - GM

The Edelbrock Throttle Cable Extension Kit for GM vehicles (part number 8012) is a precision linkage extension designed to accommodate throttle and transmission kickdown cable routing on General Motors engines. Manufactured from cadmium-plated steel, this extension solves common fitment challenges when installing aftermarket carburetors, fuel injection systems, or modified intake manifolds that alter the stock cable geometry.

The cadmium plating provides corrosion resistance and longevity, critical for engine bay longevity where moisture and heat cycling accelerate oxidation. At just 0.11 lbs with compact dimensions (1.65 x 1.2 x 5.1 inches), this extension integrates seamlessly into tight engine compartments without adding bulk or weight. The steel construction ensures rigidity under load, preventing cable slack or unintended throttle fluctuation during acceleration or deceleration cycles. This level of mechanical precision is especially important in carbureted and older fuel-injection systems where cable tension directly affects throttle response and idle quality.

Technicians and engine builders rely on this extension when relocating throttle anchor points or when transmission kickdown cables require extended routing to maintain proper engagement angles. It's an essential component for stroker builds, engine swaps, and carburetor conversions on Chevy small-block and big-block platforms, as well as other GM powerplants. The Edelbrock 8012 is engineered to restore OEM-quality throttle feel and transmission shift responsiveness without compromise, making it the go-to solution for precision fuel system and driveline modifications.
