LS 1-7/8 Ceramic Coated Mid-Length Headers for 1973-1977 A-Body
When transplanting an LS engine into a 1973 to 1977 A Body chassis finding headers that fit without grinding is essential and the 1973 to 1977 A Body LS 1 7/8 inch ceramic coated mid length headers answer that need with exact port alignment. Precision three eighth inch flanges seal flat against the cylinder head to prevent leaks and endure repeated heat cycles without warping. The ceramic coated finish reflects radiant heat away from sensitive components and guards against corrosion in demanding underhood environments. Installation is simplified by a complete hardware kit including gaskets bolts and dowels so you can spend time tuning throttle response instead of hunting for missing parts.
Precise Flange Alignment for LS Engine Swaps
The built-in 3/8" thick flanges are machined flat to match the cylinder head port surfaces, ensuring a leak-free seal even after repeated heat cycles. This exact alignment removes the need for grinding or using spacers, saving hours during the swap process and reducing error points. By maintaining the correct spacing from the steering linkage and frame rails, the headers clear surrounding components and preserve engine bay integrity. As a result, you avoid common fitment headaches and achieve consistent exhaust performance from the moment the engine fires.
Stainless Steel Construction with Ceramic Coating for Durability
Constructed from high-grade stainless steel, these headers resist rust and maintain strength under extreme temperatures. The silver ceramic coating reflects radiant heat back into the exhaust flow, lowering underhood temperature by up to 100 degrees and helping preserve nearby wiring and hoses. This finish also repels moisture and road salt, so the headers retain their appearance and function in all conditions. Over time, the combination of material and coating translates into lasting performance without warping or corrosion.
Tuned Tube Diameter and Length for Power and Tone
The 1.875-inch mid length tubes are sized to match the LS engine's torque curve, enhancing low-rpm response while still allowing top-end horsepower gains. Smooth mandrel bends keep exhaust gases moving freely, minimizing turbulence that can rob power. Inside the merge collectors, precisely positioned junctions blend exhaust pulses for a deep, throaty tone without unwanted drone at cruising speeds. These design choices deliver authentic muscle-car character with modern efficiency.
Complete Hardware Kit for Streamlined Installation
Each header set ships with factory-style gaskets, bolts, dowels and step-by-step instructions, providing everything needed for a weekend install. With all parts included, there's no second trip to the hardware store or frantic searches for missing components. The quality fasteners hold torque through relentless heat cycles, preserving the leak-free fit over thousands of miles. You can focus your time on tuning throttle response instead of troubleshooting fitment issues.
Engineered for precise fit and lasting performance in your LS swap.
