FAST Billet Fuel Rail Kit For LSXR

The FAST Billet Fuel Rail Kit for LSXR is a high-performance fuel delivery component designed to enhance fuel system efficiency for LS-based engines. Constructed from lightweight, high-strength billet aluminum with anodized finishes in red or black, these fuel rails feature a larger internal diameter that dampens fuel pulses and increases fuel volume. This design ensures injectors receive a consistent fuel supply, reducing the risk of running dry and improving overall fuel distribution. The result is increased horsepower and better engine response, making these rails an ideal upgrade for performance applications. Their show-quality appearance complements the performance benefits, providing both durability and aesthetic appeal.

Designed for LSX, LSXR, and LSXRT engines, these fuel rails are suitable for a range of vehicle builds requiring enhanced fuel delivery. They are intended as direct replacements or upgrades for compatible fuel systems, offering improved pulse damping and fuel volume. While specific fitment details are not provided, they are typically used in performance street and track vehicles. The kit does not include the associated mounting hardware (Part 146020-KIT or 146021-KIT) but is compatible with various LS engine configurations. Installation involves bolting onto the existing fuel system, making it a straightforward upgrade for enthusiasts seeking increased horsepower and reliable fuel delivery.
