Summit Racing 1 1/2" Long Tube Headers for Small Block Chevy

The Summit Racing SUM-G9006 is a set of long tube headers engineered for enhanced performance in Chevy/GMC Truck, Van, Blazer, and Suburban models equipped with Small Block Chevy engines. These headers are crafted from durable 18-gauge steel, featuring 1 1/2-inch primary tubes that smoothly transition to a 3-inch collector. The construction utilizes JIG-welded tube-to-flange plates to guarantee a precise fit and optimal sealing. These headers are manufactured for off-road and racing applications, prioritizing exhaust flow for increased horsepower. The design includes pressure-formed collectors for improved flow rates and come with necessary gaskets and collector reducers for installation. The flange thickness is 0.31 inches, and the cylinder head port shape is oval to match the engine's design. It's important to note that the included temporary non-high temperature paint is for protection during shipping and storage, and is not a final finish. It is recommended to strip this coating and apply a high-temperature paint or coating suitable for header applications before use. When installing the Summit SUM-G9006 headers, it is crucial to ensure that your vehicle is configured as it came from the manufacturer. This means that components such as cylinder heads, chassis, steering, motor mounts, body mounts, and bushings should be in their original state. If your vehicle has been modified with aftermarket parts, parts from other applications, or custom alterations, it becomes the installer's responsibility to verify fitment and compatibility.
