LSXRT Billet Fuel Rail Kit - Truck

The LSXRT Billet Fuel Rail Kit - Truck by FAST ELECTRONICS is a precision-engineered fuel delivery system designed for LS-platform engine swaps and high-performance truck builds. Built for operators and builders who demand reliable, consistent fuel distribution under demanding conditions, this billet fuel rail kit addresses the critical need for quality fuel management in custom powerplant installations. Whether you're upgrading an existing LS engine or executing a complete drivetrain swap, proper fuel rail specification is non-negotiable for engine stability and performance consistency in tactical or off-road applications.

This kit features a fully billet-aluminum construction, which provides superior corrosion resistance and structural integrity compared to cast alternatives, critical for field durability in harsh environments. The aluminum billet design minimizes thermal expansion issues and maintains precise fuel pressure regulation across the entire fuel delivery spectrum. The rail assembly includes all necessary components for LS-series engine integration, with carefully engineered port positioning to ensure even fuel distribution and optimal injector spray patterns. At 2.6 lbs, the compact assembly (8.5 x 4 x 19 inches) fits cleanly within modern truck engine bays while maintaining accessibility for service and adjustment.

This kit is ideal for truck builders, powersports enthusiasts, and technicians performing LS engine conversions who cannot compromise on fuel system reliability. The LSXRT configuration is specifically tuned for truck-platform dimensions and mounting points, ensuring straightforward installation without custom fabrication. Compatibility with LS-series engines—including LS1, LS2, LS3, and LS9 variants—makes this a versatile choice across generations. Professional-grade construction means extended service life in both street and field conditions, with the billet aluminum construction resisting fuel degradation and temperature extremes that compromise lower-grade alternatives.
