1968-1972 A-Body LS 1-7/8 Ceramic Coated Mid-Length Headers
When fitting an LS powerplant into a 1968 to 1972 A-Body frame, exhaust routing and clearance often present the biggest obstacles in a swap project. These headers bolt directly to the factory mounts and align perfectly with standard LS mount kits. Constructed with 1.875 inch primary tubes and 3/8 inch thick flanges they maintain optimal scavenging and stand up to repeated heat cycles. A ceramic barrier coating reflects heat back into the exhaust stream and guards against corrosion for dependable performance.
Precision Engineered 1.875 Inch Primary Tubes
The 1.875 inch primary tubes are mandrel bent to preserve a constant diameter through each curve, minimizing turbulence and stress points that can lead to early fatigue. This careful shaping balances exhaust gas velocity with flow volume, enhancing cylinder scavenging for stronger low-end torque and elevated peak power. By maintaining smooth transitions, these headers deliver a more linear power curve and sharper throttle response across the rev range. The result is a noticeable improvement in drivability whether on the street or at the strip.
Robust 3/8 Inch Flange Design for Seal Integrity
Each flange is machined from heavy gauge steel at a full 3/8 inch thickness to resist warping under extreme temperature cycles. When paired with the provided gaskets and hardware, this sturdy mounting surface forms a uniform, leak free seal against the cylinder head. Eliminating exhaust leaks at the joint preserves consistent scavenging effects and reduces unwanted noise and emissions. Durability is maximized, ensuring the mating surfaces remain true even after repeated heating and cooling events.
Ceramic Coating for Thermal Management and Corrosion Defense
The silver ceramic barrier finish reflects radiant heat back into the exhaust system to reduce under-hood temperatures and limit heat soak into nearby intake and ignition components. This thermal control helps preserve spark plug longevity and improves air charge density for more efficient combustion. In addition, the coating seals the steel substrate against moisture and road salts, preventing rust and pitting over years of use. The protective layer also retains a bright appearance, keeping the engine bay looking clean.
Custom Fit for 1968 to 1972 A Body LS Installation
These mid-length headers are tailored precisely to the factory mounting points of '68 to '72 A Body frames, eliminating the need for manifold spacers or trimming. They align seamlessly with standard LS mount kits to simplify installation and save valuable workshop time. With exhaust routing cleared around front suspension and steering components, installers can achieve a straight bolt in fit without trial-and-error modifications. This design focus ensures a hassle-free swap and reliable performance from day one.
Built for reliable operation and exact fit, these headers ensure smooth installation and consistent exhaust flow.
