FULL HIGHLIGHTS

Xcelerator Metering Rod

Instant Response. No Bog. All Throttle.

Designed to mimic an accelerator pump—without the complexity—the Xcelerator Metering Rod delivers fuel precisely when you need it. Whether you’re rolling it on or whacking it wide open, this circuit reacts instantly for throttle response you didn’t think a carb could deliver.

Power Jet (Top-End)

No Compromise. Top-End Control. No Tools Required.

Confidently dial in your low-end with the metering rod without top end compromise. The Power Jet circuit lets you adjust fuel delivery at high RPMs without disassembly and is independent of the metering rod—so you can confidently tune your bottom-end without sacrificing the top.

Air-Redirect Slide

Targeted Airflow. Sharper Response.

Engineered to channel low-throttle airflow directly at the metering rod, this slide enhances fuel signal where it matters most. Better signal means better response, especially in off-idle and low-RPM situations.

Tailored Bore Design

Matched to Your Engines Displacement. Built for Real Power.

Our bore isn’t one-size-fits-all—it’s precision-matched to your engine’s displacement for optimal air velocity and fuel signal. That means stronger throttle response, more usable torque, and smoother power delivery across the RPM range. Power made for you.

Billet Aluminum Construction

Stronger. Lighter. Built to Perform.

Machined from solid billet aluminum, this body delivers superior strength, tighter tolerances, and a premium finish. It’s lighter, tougher than plastic, and designed to withstand heat, vibration, and abuse—ride after ride.
