1970–1972 Big Block Chevy Choke Kit – Quadrajet (Q‑Jet)

One of the most important components of a properly tuned and running engine is a choke system that operates correctly. This high-quality reproduction Quadrajet choke kit is designed for 1970–1972 Chevrolet big block applications equipped with a Rochester Quadrajet carburetor.

The original factory choke assemblies used a thermo-spring coil that gradually released as engine temperature increased. After decades of use, many original choke components have become worn out, damaged, or discarded during carburetor swaps, intake manifold changes, and other modifications.

Bowtie Muscle Parts is proud to offer this complete reproduction choke kit for Chevrolet 396, 402, and 454 big block engines. This convenient kit includes the components needed to restore proper factory-style choke operation and appearance.
