Automatic Divorce Choke Rod - GM

The Automatic Divorce Choke Rod for GM is a precision carburetor component engineered to regulate and optimize choke operation on General Motors engines equipped with automatic choke systems. Designed for enthusiasts and mechanics restoring or tuning classic GM powerplants, this rod manages the mechanical linkage that controls choke plate positioning during cold starts and warm-up cycles. It's an essential replacement part for anyone addressing stalling issues, rough idle, or excessive fuel consumption caused by worn or misaligned choke mechanisms.

Edelbrock's Automatic Divorce Choke Rod is manufactured to exact OEM specifications, ensuring proper engagement between the choke thermostat housing and the choke butterfly valve. The compact 5.7-inch length and lightweight design (0.04 lbs) allow for easy installation without requiring extensive carburetor disassembly. This rod's precision geometry maintains proper choke actuation travel, preventing binding or slack that would compromise fuel atomization and engine response during the critical warm-up phase.

Mechanics and restoration specialists rely on this component when rebuilding Edelbrock or OEM automatic choke carburetors on 1960s–1980s GM engines. Installation requires removing the choke housing and threading the rod through the linkage assembly—a straightforward operation for anyone with basic carburetor experience. Verify compatibility with your specific GM engine and carburetor model before ordering to ensure proper fitment and choke function.
