1968-1972 A-Body LS 1-7/8-Inch Ceramic Coated Mid-Length Headers
Installing an LS into a 1968 to 1972 A-Body often runs into tight clearances along the frame rails and steering linkage so these ceramic coated mid length headers are built for that exact challenge. Each tube uses GM specific flanges and precision port alignment to clear suspension parts without trimming or bending. The ceramic finish traps radiant heat inside the exhaust stream to reduce underhood temperatures and protect wiring and sensors. With optimized 1 7/8 inch primaries the design balances low rpm torque and high rpm flow for a wide power band on both street and track.
Ceramic Coating That Manages Radiant Heat
These mid length headers feature a durable ceramic coating applied to each steel tube surface. By reflecting radiant heat inward toward the exhaust stream, the system maintains hotter gas temperatures for faster scavenging and lower backpressure. This thermal barrier also limits heat transfer to the engine bay, protecting sensitive wiring, sensors and intake components from heat soak. Over time the coating prevents surface corrosion on the steel substrate and resists cracking under repeated expansion and contraction. The result is consistent power delivery and reliable underhood performance in all conditions.
Steel Construction With Mandrel Bends And Thick Flanges
Fabricated from thick wall steel tubing, these headers are built to withstand the rigors of daily driving and track use. Each curve is formed using mandrel bending techniques that preserve a constant internal diameter, eliminating turbulence and flow restrictions at every turn. The three eighth inch flanges are precision machined flat to create a tight seal against the cylinder head, preventing exhaust leaks even under high backpressure. Combined with sturdy welds, this robust construction ensures long term resistance to warping, cracking and thermal fatigue.
Optimized 1 7/8 Inch Primaries For Versatile Torque And Power
The choice of 1 7/8 inch primary tubes reflects a careful balance between low speed torque and high speed flow. At low rpm the diameter supports strong exhaust scavenging, resulting in sharper throttle response and improved off the line acceleration. As engine speed climbs, the same sizing allows sufficient volume to feed peak horsepower without creating excessive backpressure. This geometry creates a smooth transition through the rev range, enhancing fuel efficiency and providing a wide power band for both street driving and competition applications.
Direct Fit Design For Simplified Installation
Engineers developed these headers with GM specific flanges and port alignment to match factory cylinder heads without modification. The mid length routing avoids interference with frame rails, steering linkages and suspension components, so there is no need for trimming or bending during installation. Installers can bolt on the headers using the included gaskets and hardware, reducing labor time and ensuring precise fitment. This direct fit approach allows enthusiasts to complete a swap cleanly and quickly, focusing on performance upgrades rather than fabrication work.
