Edelbrock 1455 Performer Series Carburetor Metering Rods .073 x .042 Inch Pair

The Edelbrock 1455 metering rods are precision-engineered replacement components designed for Edelbrock Performer Series and Thunder Series AVS carburetors. These metering rods play a critical role in controlling fuel flow through the carburetor's primary metering system, directly affecting engine performance, fuel economy, and throttle response.

Key Specifications:

• Primary diameter: .073 inches
• Secondary diameter (power tip): .042 inches
• Includes 2 metering rods (one pair)
• Compatible with Edelbrock Performer Series and Thunder AVS carburetors
• Precision-machined for accurate fuel metering

Metering rods work in conjunction with metering jets to regulate fuel delivery based on engine load and vacuum conditions. The dual-diameter design allows the carburetor to transition between lean cruise conditions and richer power settings. The larger .073-inch diameter restricts fuel flow during light throttle operation, while the smaller .042-inch power tip allows increased fuel flow when the metering rod lifts under acceleration or heavy load.

Edelbrock offers metering rods in various size combinations to allow fine-tuning of air-fuel ratios for specific engine combinations, altitude conditions, and performance requirements. Changing metering rod sizes is one of the primary methods for optimizing Edelbrock carburetor calibration.
