1968-1972 A-Body LS Ceramic Coated 1-7/8-Inch Mid-Length Headers
The 1968 through 1972 A Body LS one and seven eighths mid length headers address tight frame rail clearance and route exhaust through a ceramic coated finish that cuts underhood heat and resists corrosion. Formed from three eighths inch thick steel each primary tube matches LS cylinder head ports to guide combustion gases efficiently. Factory style flanges and included gaskets complete a precise seal without modifications or extra parts and make installation straightforward. This design preserves sharp throttle response and consistent torque delivery throughout the rev range.
Precise Fitment for 1968 to 1972 A Body LS Conversions
The mid length header bodies are shaped to clear the narrow frame rails found on classic 1968 through 1972 A Body sedans and coupes when mated with LS engines. Factory style flanges align precisely at the port faces without any trimming or modification, so installers can rely on original mounting points to guide the hardware into place. Supplied gaskets and bolts complete the seal, preventing leaks that can reduce performance and endanger nearby components. The routing of each primary tube matches cylinder head ports one to one, ensuring equal length pathways that support balanced scavenging and improved power delivery. This custom fit delivers a plug and play installation that keeps steering and suspension brackets free from unwanted interference, saving time while ensuring reliability.
Durable Three Eighths Inch Steel Construction
Each primary tube is formed from three eighths inch thick steel to withstand the extreme temperature cycles created by LS exhaust flows. This wall thickness provides the rigidity needed to resist deformation under heat and vibration, so the sealing surfaces remain flat and gaskets hold their compression. Steel material also offers robust fatigue resistance, delivering long term durability even in trucks that see heavy duty use. Welds are precisely executed to maintain consistent wall thickness and avoid weak points, ensuring the header assembly remains leak free through repeated heating and cooling events. Precision formed bends avoid kinks and preserve a uniform cross section throughout each curve, which further reduces turbulence and backflow.
High Temperature Ceramic Coating for Heat Management and Corrosion Protection
A silver colored ceramic layer covers each tube and flange to reflect radiant heat back toward the exhaust stream, accelerating gas velocity and lowering underhood temperatures. This reduction in ambient heat helps protect wiring harnesses, hoses and electronic sensors from premature aging and ensures a safer engine bay environment. The coating also acts as a barrier against moisture, road salt and debris, reducing the onset of rust and pitting over years of service. By preserving the structural integrity of the header tubes, the finish helps maintain consistent performance while keeping the engine compartment clean and presentable.
Optimized One and Seven Eighths Inch Tube Sizing for Balanced Flow and Torque Delivery
The one and seven eighths inch primary tubes strike a precise balance between exhaust gas velocity and volume to support a wide torque curve across all rpm ranges. At low engine speeds, the sizing enhances scavenging in the cylinders to improve throttle response during city driving and light acceleration. As rpm climbs, the design minimizes backpressure so the LS engine can breathe freely and sustain power output at higher speeds. Such attention to diameter and spacing helps maintain optimal pulse timing that benefits both low end torque and high rpm horsepower. This calibration fosters smooth acceleration, consistent midrange torque and an engaging driving experience whether towing, hauling or cruising on the highway.
