Hi-Ram Fuel Rail Kit LS3/L92/LS7

The Holley Hi-Ram Fuel Rail Kit for LS3, L92, and LS7 engines is a precision fuel delivery system engineered for high-performance GM LS-series applications. This aluminum fuel rail assembly is finished in black anodized coating, providing both corrosion resistance and a professional appearance. The Hi-Ram kit delivers consistent fuel supply across all cylinders, critical for maintaining engine performance under demanding conditions—whether on the dyno, at the track, or during sustained high-load operation.

The fuel rail's aluminum construction balances weight savings with structural rigidity required for injection system stability. Black anodizing protects the aluminum substrate against oxidation and thermal stress in the engine bay, extending service life in high-temperature environments. This kit is specifically designed to work with LS3, L92, and LS7 cylinder heads, ensuring proper fuel injector spacing, port alignment, and fuel distribution characteristics that maximize combustion efficiency. The complete assembly includes all necessary fittings and components for bolt-on installation into compatible LS platforms.

This fuel rail kit serves builders, performance shops, and enthusiasts upgrading LS-series engines for improved fuel delivery accuracy and system reliability. Whether upgrading a stock fuel system for turbocharging, building a road-race engine, or converting a carbureted drivetrain to fuel injection, the Hi-Ram kit provides OEM-quality fuel rail performance. Weighing 3.05 lbs with compact dimensions (7.6 × 1.05 × 20.8 in), it installs cleanly without requiring extensive engine bay modifications on properly prepared LS installations.
