Black Billet Fuel Rail Kit With 6AN Ports For LS1 LS6 Intake

Upgrade your build with this black billet fuel rail kit designed specifically for OE-style LS1 and LS6 intake manifolds.

The half-inch inner bore moves enough fuel to feed engines pushing over 1,100 horsepower.

That generous passage prevents the pressure drops and back pulses that choke high-output setups.

Fuel reaches every injector evenly, so you get consistent power and smooth idle.

CNC-machined from solid aluminum, these rails hold their shape under heavy vibration.

A durable anodized black finish resists chemicals and keeps your engine bay looking clean.

Benefits & Tips

• Match with a tunable ECU to unlock the full flow potential and dial in precise air-to-fuel targets.
• Route the crossover hose gently to avoid sharp bends that restrict vapor return or cause rubbing.
• Apply an alcohol-safe thread sealant to all six-millimeter AN fittings during reassembly for lasting leak-free performance.
