External Throttle Linkage shaft Kit, 4500

BLP Products is proud to introduce a NEW external linkage system for the Holley® 4500 HP series carburetors. This revolutionary design moves all the linkage from underneath the carburetor allowing the racer to change linkage ratios from 1:1 to 3 different progressions all on the outside of the carburetor. Each change can be made within seconds.

• Thinned throttle shafts provide up to an extra 15 CFM over a stock throttle shaft
• 4 different progressions available in a matter of a few seconds. No more tearing the carburetor completely apart to change linkage ratios
• Available for four different bore sizes 2.000-2.125-2.190-2.375
