Allstar Performance Carb Shear Plate – Holley 4150 – 1-3/4″ Bore

Carb plates with built-in shear design help maximize performance on race engines with a large amount of cam overlap by creating a dam under the throttle plates, helping to build low pressure while improving vacuum signal to the carb. 1/2″ tall plates are machined from 6061-T6 aluminum and clear anodized to protect against corrosion.
