The JBA Cat4Ward shorty header for 2002–2008 Dodge Ram 3.7L V6 uses 1-1/2" primaries and raw 409 construction to reduce restriction and enhance low-end torque. Mandrel-bent tubes, 3/8" machined flanges and the Firecone collector design help the engine breathe better in daily driving and towing. Oversized ports, factory-style emission connections and robust hardware deliver a reliable, leak-free installation.
