FAST Billet Fuel Rail Kit For LSXR

MPN: 146033B-KIT Catalog #: 001133706 Category: Fuel Rails Check Vehicle Fitment

Product Details

FAST LSX/LSXR/LSXRT Fuel Rails feature a larger internal diameter that dampens the pulses and provides increased fuel volume, ensuring that your injectors never run dry. In addition, they yield better fuel distribution and ultimately greater horsepower. Featuring high strength billet, lightweight, red or black (specific applications) anodized aluminum construction (does not include Part 146020-KIT or Part 146021-KIT), FAST fuel rails deliver performance in addition to a show car quality appearance.

This Billet Fuel Rail kit for LS2 engines includes billet fuel rails and mounting brackets designed to mount an LS2 fuel injector to our 146302B 102mm intake manifold.

See 146033-KIT for red rail option. 146302B w/ LS2 injectors require no injector adapters for use with OE rails/brackets.
