FST146027-KIT - FAST LSXR LS3/LS7/L76/L99 Billet Fuel Rail Kit

This product may require vehicle validation(s) for proper fitment. Please contact us to confirm correct vehicle fitment and usage.



The 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 anodized aluminum construction (does not include Part #146020-KIT), FAST™ fuel rails deliver performance in addition to a show car quality appearance. The FAST™ fuel rails are available in a component matched kit, including black anodized #8 fittings and super seal o-rings.
