Billet Bullet Carburetor Spacer

   

Our Billet Bullet carb spacers provide superior power gains in a wide variety of applications. We offer spacers for Holley 4150, 4500, and Braswell 4825 series carbs. They raise the carburetor from 3/4" to 2" as best needed by your intake and cam combination and are available for most throttle bore sizes. Our catalog also includes several application specific spacers for circle track and spec motors.

Our proprietary 4 hole to open spacer transitions outflow the competition. The smoothed flow results in a stronger vacuum signal to the boosters for a broader torque curve and improved throttle response. Horsepower gains are made through the entire power band and the carburetor will often flow beyond its rated CFM.

Anodizing is available for volume orders.
