Billet Fuel Rail Kit for LS2 LSXr 102mm Intake

The Billet Fuel Rail Kit for LS2 LSXr 102mm Intake from FAST Electronics is a precision-engineered fuel delivery system designed for serious LS platform engine builders and performance enthusiasts. This kit addresses the critical need for consistent, high-pressure fuel delivery when upgrading to a larger intake manifold on LS2 and LSXr engines with 102mm bore applications. Whether you're tuning a street machine, track car, or building a complete engine swap, proper fuel rail architecture is non-negotiable for reliable power and drivability across all engine speeds and load conditions.

Constructed from billet aluminum, this fuel rail kit delivers superior strength and corrosion resistance compared to cast alternatives, while maintaining tight tolerances required for high-flow fuel management systems. The billet construction allows for precision porting and optimized internal passages that minimize fuel turbulence and pressure drop, ensuring stable injector spray patterns at elevated boost levels or high RPM. FAST Electronics engineered this kit specifically for 102mm intake manifolds, accounting for the unique port spacing and mounting geometry of LS2 and LSXr heads to guarantee proper fuel distribution to all eight injectors without modification or adapter complications.

This fuel rail kit is ideal for engine builders performing intake upgrades, forced induction installations, or complete LS2/LSXr engine builds where OEM fuel rail compatibility is compromised. Mechanics and tuners benefit from the drop-in design that eliminates fitment guessing, while the billet construction survives the rigors of high-performance applications without cracking or leaking under sustained pressure cycling. Installation requires basic fuel system knowledge and proper attention to sealing and line routing; the compact 9 x 4 x 19 inch footprint fits within typical engine bay constraints on both street and race vehicles using LS2 or LSXr platforms with 102mm intake specifications.
