The FAST Billet Fuel Rail Kit for LSXR is a high-performance fuel delivery component designed for LS-based engines. Constructed from lightweight, high-strength billet aluminum and available in red or black anodized finishes, these fuel rails feature a larger internal diameter that effectively dampens fuel pulse vibrations and increases fuel volume. This design ensures consistent fuel delivery, preventing injectors from running dry, and promotes improved fuel distribution across the intake manifold. The result is enhanced horsepower and overall engine performance, making these rails an ideal upgrade for serious street and track applications. Their show-quality appearance complements high-performance builds, combining durability with aesthetic appeal.

Designed for LSX, LSXR, and LSXRT engines, these fuel rails are compatible with a range of Chevrolet performance vehicles. They serve as direct replacements or upgrades for stock fuel rails, fitting specific applications with the appropriate mounting configurations. Installation is straightforward, typically bolt-on, and intended for use in high-performance or modified engines where increased fuel capacity and pulse dampening are beneficial. Please note that this kit does not include Part 146020-KIT or Part 146021-KIT. Suitable for street, track, or racing environments, these fuel rails deliver reliable fuel flow and a premium appearance for demanding automotive enthusiasts.
