Description
Header bolts endure extreme thermal cycling and vibration—standard fasteners simply won’t hold up. ARP’s stainless steel construction resists corrosion and maintains clamp load where it matters most, ensuring your header stays sealed and your engine performs consistently. This polished, drilled kit delivers both durability and a finished appearance under the hood.
