Product Description

The Stainless Works HFJP61188 Header Flanges provide the foundation for custom header fabrication on Gen III Hemi engines. Laser-cut from heavy-duty 3/8" thick 304 stainless steel, these D-Port shaped flanges deliver superior resistance to warping from extreme exhaust temperatures compared to mild steel alternatives. The precision laser cutting ensures accurate port alignment with factory Hemi cylinder heads on 5.7L VVT, 6.1L SRT8, and 6.4L 392 applications.

Designed for 1-7/8" primary tube diameter, these flanges are ideal for building high-performance long tube headers or replacing damaged flanges on existing custom headers. The thick 3/8" construction provides a rigid, flat mounting surface that maintains a secure seal against the cylinder head. Sold as a matched pair and backed by Stainless Works' limited lifetime warranty on material and craftsmanship, these flanges are proudly manufactured in the USA at Stainless Works' facility in Streetsboro, Ohio.
