Quadrajet Electric Choke Conversion Kit

The JET PERFORMANCE Quadrajet Electric Choke Conversion Kit (MPN 201355) transforms manual-choke Quadrajet carburetors into modern electric-choke systems. This retrofit conversion eliminates the mechanical complexity of manual choke operation while maintaining the proven reliability and fuel-delivery characteristics that made Quadrajet carburetors the standard on full-size American engines from the 1960s through 1980s. The kit delivers complete wiring harness and mounting hardware required for a clean, functional electric choke retrofit.

This conversion addresses a critical real-world problem: manual choke operation requires learning a specific technique for cold starts, and the mechanism can stick or fail from fuel varnish buildup in long-term storage. An electric choke solves this by delivering consistent heating to the bimetallic spring through an electric element, eliminating guesswork at startup. The included wiring connects directly to vehicle charging circuits, providing automatic temperature compensation without operator intervention. All necessary hardware is supplied—no sourcing additional fasteners or adapters.

This kit is designed for engine builders, classic car restoration specialists, and hot rod enthusiasts working with Quadrajet four-barrel carburetors on small-block and big-block applications. It suits owners seeking improved drivability and cold-start reliability in vintage vehicles without replacing the original carburetor. Weighing just 0.29 lbs and dimensioned for compact installation, the conversion preserves OEM carburetor aesthetics while modernizing function. Quadrajet electric choke conversions are common in street rods, muscle car restorations, and vintage truck builds where reliability matters.
