Billet LSXRT Fuel Rail Kit

The FAST LSXRT Billet Fuel Rail Kit is engineered to enhance fuel delivery for GM Truck/SUV 4.8, 5.3, and 6.0L engines equipped with the LSXRT intake manifold. This kit is constructed from high-strength, lightweight anodized aluminum, offering a durable solution with a premium, show-car aesthetic. The fuel rails boast a larger internal diameter, which effectively dampens fuel pulses and guarantees sufficient fuel volume to prevent injectors from running dry under demanding conditions. This improved fuel distribution contributes to better overall engine performance and ultimately, greater horsepower. Compatibility is specifically for GM Truck/SUV 4.8, 5.3, and 6.0L engines utilizing the LSXRT intake manifold. Please note that the LSXRT intake manifold is sold separately. This kit can be configured for LS2-style injectors. If using OEM injectors, a lower O-ring swap is required, utilizing part #54043-602, which is included with the manifold.
