Carb Insert 2in Tall 1.125in Diameter

The Carb Insert 2in Tall 1.125in Diameter by Wehrs Machine is a precision-engineered restrictor plate insert designed for engine builders and performance tuners working within regulated competition and street engine applications. This aluminum spacer insert fits into Wehrs Machine's modular carburetor spacer system and provides exact bore diameter control at 1.125 inches, enabling consistent fuel delivery metering across a range of engine configurations.

Manufactured from durable aluminum in natural finish, the 2-inch tall insert measures 2.75 x 1.85 x 7.5 inches overall and weighs 0.9 lbs, making it a lightweight addition to your carburetor stack-up. The 1.125-inch bore diameter is critical for regulations requiring air restriction in drag racing, circle track, and other sanctioned motorsports where intake air metering must meet specific class rules. Wehrs Machine spacer systems are built for easy stacking and removal, allowing tuners to swap inserts quickly between competition events or test sessions without complete carburetor disassembly.

This insert is ideal for engine builders, racing teams, and dedicated enthusiasts running sanctioned competition vehicles in classes that mandate intake air control devices. Whether you're preparing a Pro Stock engine, Super Street competitor, or bracket racing platform, the Wehrs Machine carburetor spacer system with these bore-specific inserts ensures compliance with technical rules while maintaining repeatability across multiple test runs and qualifying sessions. The natural aluminum finish resists corrosion in typical garage and shop environments, and the modular design lets you maintain a toolbox of inserts for different competition events or engine combinations.
