Carburetor Spacer Adjustable Angled 2 Inch Thick 4 Hole Square Bore Aluminum Black Anodized Each Allstar Performance

Four-hole aluminum spacer angles the carburetor left and to the rear so the carb is closer to level when in race attitude. Spacer accepts 1/2 Inch or 1 Inch tapered inserts which can be changed quickly by removing the carb.

Inserts restrict air/fuel entry and reduce power slightly to prevent wheel spin and range in size from 0.950 Inch to 1.400 Inch for custom tailoring and quicker lap times. Spacer works with most Holley 4bbl.

4150/4160 series carburetors. Inserts sold separately.
