The Aeromotive billet fuel rails for GM LS1/LS6 applications (1997–2004 LS1 and 2001–2005 LS6 rails only) are engineered for high-flow fuel delivery with ORB-08 ports and a full 5/8" ID through bore. They provide full-size end ports for steady injector supply and include additional plumbing ports where needed. CNC-machined billet construction and custom steel mounting brackets deliver a durable, bolt-on installation.
