Vic Edelbrock, Sr. engineered the original progressive triple carburetor linkage in the late 1950's, providing a bolt-on linkage solution for multiple carburetor set-ups. The progressive design operates a single or two carburetors to half throttle and then progresses the third carburetor and synchronizes the opening of all three carburetors at wide open throttle. Edelbrock 94 carburetors are equipped with an extended length throttle shaft, making these kits a bolt-on to Edelbrock 94 carbs.

-Operates a single or dual carb to half throttle and progresses all three to WOT
-Saves fuel, provides smoother throttle operation and ends flat spots
