Description
Stock header bolts corrode, seize, and fail under sustained heat and vibration—leaving you stranded mid-season or worse, causing catastrophic engine damage. ARP’s stainless steel header bolts are engineered to withstand extreme exhaust temperatures and cyclic stress without galling or loosening, ensuring your headers stay secure through thousands of heat cycles. The 12-point design provides superior grip during installation and removal, eliminating the frustration of rounded fasteners.
This universal kit contains everything needed for most header applications, and the polished stainless finish resists corrosion while adding a professional appearance to your engine bay.
