Allstar Performance 4500 Shear Plate: Maximize Induction Efficiency

The Allstar Performance Shear Plate is a critical component for high-performance engines utilizing a 4500-series Dominator carburetor. Designed to improve air-fuel mixture quality, this 0.5-inch thick aluminum plate helps shear the fuel charge as it enters the intake manifold, leading to better atomization and increased horsepower. If you are looking to squeeze every bit of performance out of your race engine, this is the precision part you need.

Key Specifications

  • Compatibility: Designed for 4500 Dominator Flange carburetors
  • Bore Size: 2.000-inch diameter for high-flow applications
  • Thickness: 0.5-inch profile for optimal plenum volume
  • Material: Lightweight, high-strength aluminum
  • Configuration: 4-hole design for improved signal and distribution

Precision-machined for a perfect seal, this shear plate is an essential upgrade for drag racing and high-output street applications. By smoothing the transition from the carburetor venturi to the intake manifold, you reduce turbulence and optimize airflow. The natural aluminum finish is durable and ready for high-heat environments. When you need reliable, track-proven components for your fuel system, look no further than the selection available at GGCRACING.
