Throttle Rod Ext. Kit - GM

The Throttle Rod Extension Kit for GM vehicles from Edelbrock is a precision linkage solution designed for carburetor and fuel injection throttle cable management in classic and modified engines. This kit addresses a common challenge faced by engine builders and transmission swappers: maintaining proper throttle cable geometry when engine placement, intake manifold height, or accessory bracket configuration shifts during a rebuild or upgrade. Whether you're installing a crate engine, modifying cylinder head placement, or adapting a carburetor to a non-original mounting position, this extension kit preserves smooth throttle response and cable longevity.

Constructed from steel with zinc oxide plating, the Throttle Rod Extension Kit features a 7.5-inch extension length that accommodates typical engine bay offset scenarios without introducing binding or slack in the linkage. The steel construction provides rigidity and durability under repeated throttle cycles, while the zinc oxide finish resists corrosion from engine heat and humidity. The compact, lightweight design (0.2 lbs) integrates seamlessly into existing throttle linkage assemblies, and the rod mechanism allows for precise cable routing adjustments. This is essential when intake manifolds are repositioned, superchargers or intercoolers occupy stock cable paths, or custom engine mounts alter the relationship between throttle pedal geometry and carburetor throttle body position.

Professional engine builders, street rod fabricators, and GM performance enthusiasts rely on this extension kit during engine swaps, turbo conversions, and high-displacement engine installations where factory cable routing no longer works. The kit is compatible with GM carburetors and fuel injection throttle actuation systems, making it ideal for LS engine swaps into older platforms, big-block upgrades, and custom engine bay layouts. Installation requires basic hand tools and an understanding of linkage geometry; ensure cable travel is linear and free from interference when routed through the extension. This product eliminates the need for custom fabrication and reduces installation time on complex projects.
