Header Tab Kit

The SCHOENFELD Header Tab Kit (Model 4003-6) is a complete fastening solution designed for header installation and exhaust system assembly in performance and engine rebuild applications. This kit bundles all the hardware necessary for secure, repeatable header mounting: 12 steel tabs, 6 bolts, 6 lock nuts, and 12 washers in a single package.

Construction from steel provides the strength and heat resistance required for engine compartment duty, where vibration and thermal cycling demand hardware that won't loosen or fail. The inclusion of lock nuts ensures the bolts remain secure during extended operation—critical in high-vibration environments where standard fasteners may back out. Twelve washers distributed across the six bolt positions allow for even load distribution, reducing the risk of stripping holes or damaging tab surfaces during installation and future service.

This kit serves engine builders, performance technicians, and serious enthusiasts who demand OEM or OEM-equivalent hardware for header installation. Whether working on a fresh engine build, upgrading to a high-flow exhaust manifold, or rebuilding with factory-spec fasteners, the Header Tab Kit eliminates the need to source hardware separately. The set-of-6 configuration supports dual-bank header systems or provides a complete solution for single-side work with spares on hand.

Schoenfeld is recognized in the automotive performance sector for precision engine components and fastening kits engineered to match OEM specifications. Weighing 0.74 lbs and compactly dimensioned, this kit fits easily in a tool kit or shop drawer, ready for the next project or service interval.
