Specifications

Headers, Tri-5, Mid Length, Steel, Ceramic Coated, Chevy, Small Block, Pair

Patriot's popular 1955-57 Chevy passenger car headers for small block, big block, and LS1/LS6 swaps offer superior performance and fit. These headers feature durable 18-gauge tubing, accommodate the GM 605 power steering box conversion, and fit most motor mounts. Their extra ground clearance makes "slammed" cars drivable and above-frame rail exhaust system installation easy. Patriot Tri-5 headers come with gaskets, header bolts, and collector reducers.

Unless otherwise noted, these headers are designed to fit the vehicle as it came from the manufacturer. This includes components like cylinder heads, chassis, steering, motor mounts, body mounts and bushings, etc. If your vehicle is using aftermarket components, parts from other applications, or custom altered parts, then it is the installer's responsibility to verify fitment.

Finishes available:
• Metallic Ceramic Thermal Barrier Coating (MCTBC), which is 60 percent more corrosion-resistant than an unpolished surface, easy to maintain, and will last for years under normal operation conditions. MCTBC also protects the headers by creating a thermal barrier (heat-resistant up to 1,600 degrees F) that significantly lowers underhood temperatures and protects the substrate metal from thermal fatigue.
• Hi-Temp black coating is an affordably priced alternative to their MCTBC. This finish provides good corrosion and heat protection.
• Raw steel is available for individual customizing
