Mid-Length Ceramic Coated LS Headers for 1973-1987 2WD Truck Engine Swaps
If you are tackling an LS engine swap in a 1973 to 1987 GM two wheel drive truck, these 1 7/8 ceramic coated mid length headers deliver the precise fit and airflow improvement needed for reliable performance. With a robust 3/8 inch thick flange that seals firmly to the block and a high temperature ceramic coating that shields engine bay components, these headers help maintain consistent exhaust flow under load. Designed specifically for GM two wheel drive trucks from 1973 through 1987 running LS powerplants, installation is straightforward when paired with compatible mount kits. The result is a well rounded blend of durability and throttle response that keeps your classic ready for hauling and towing tasks.
Durable Steel Construction With Thermal Protection
The headers are built from robust steel tubing that handles the stress and heat of LS operation in classic GM trucks. This material choice offers a balance of strength and cost efficiency, resisting cracking or warping under exhaust temperatures. The silver ceramic coating acts as a heat barrier that reflects radiant heat back into the exhaust stream, reducing underhood heat and protecting nearby components from heat soak. Over time this coating also resists corrosion, ensuring the headers maintain structural integrity and appearance through heavy use.
Precision Flange Ensuring Leak Free Seal
The three eighths inch thick flange is machined flat to deliver consistent rigidity and a leak free joint to the LS block. This substantial thickness prevents warping during repeated heat cycles, preserving uninterrupted contact with the cylinder head. Such seal integrity stops exhaust leaks that can sap performance and create hot spots under the hood. When paired with premium gaskets and bolts the flange provides dependable sealing for consistent horsepower and torque delivery under load.
Optimized 1 7/8 Inch Mid Length Design for Smooth Flow
Featuring one and seven eighths inch primaries, the mid length design strikes a balance between scavenging efficiency and engine bay clearance on 1973 to 1987 two wheel drive GM trucks. This diameter optimizes exhaust velocity across the rpm range, translating into improved throttle response and a broader power band. Unlike full length headers that may conflict with frame rails, the mid length layout allows flexible routing while maintaining ground clearance for daily driving. The result is a smooth power delivery that enhances both towing performance and everyday use.
Engine Swap Fitment and Simplified Installation
Purpose built for LS swaps in GM two wheel drive trucks from 1973 through 1987, these headers align precisely with factory port locations and mounting points. They integrate seamlessly with compatible header mount kits, reducing the time and adjustments needed to secure them. The included gaskets and bolts further streamline the process by eliminating guesswork on fastener selection. Installers achieve a precise fit and reliable operation without extensive fabrication or modification.
Engineered for precision-fit and reliable performance in your LS swap project.
