1968-1972 A-Body LS Ceramic Coated Mid-Length Headers
Facing tight steering column and crossmember clearance when dropping an LS into a 1968 to 1972 A Body, installers rely on the 1968 to 1972 A Body LS 1 7/8 inch ceramic coated mid length headers to deliver a precise fit without fabrication. Made from heavy gauge steel, the tubes maintain their form under thermal cycling while uniform bends support efficient exhaust scavenging across the rev band. A silver ceramic finish doubles as a reflective ceramic barrier to reduce underhood heat and shield wiring and hoses. Flanges machined to stock thickness and included hardware provide a straight bolt on installation.
Optimized 1 7/8 Inch Primary Tube Design for Enhanced Scavenging
The precisely sized 1 7/8 inch primary tubes are engineered to match the exhaust pulse timing of an LS engine, ensuring efficient scavenging across a broad RPM range. Smooth mandrel bends maintain a constant diameter through each curve, reducing turbulence and minimizing backpressure that can sap midrange torque. Consistent tube length balances pressure waves to promote a more linear throttle response, so drivers experience stronger pull throughout the rev band. This level of calibrated flow not only unlocks measurable horsepower gains but also helps the engine breathe more freely under load, improving both daily driveability and spirited acceleration.
Silver Ceramic Barrier for Underhood Heat Reflection
A durable ceramic coat applied to each primary and collector surface forms a reflective barrier that directs radiant heat back into the exhaust stream. This reflective ceramic barrier lowers underhood temperatures by as much as 50%, shielding sensitive wiring, hoses, and intake plumbing from heat soak during prolonged operation. By retaining thermal energy inside the tubes, the coating also enhances exhaust velocity, which further improves scavenging efficiency. Over time, this finish resists corrosion and surface fatigue, extending the service life of the headers even under repeated high-temperature cycling.
Heavy Gauge Steel Endurance Through Thermal Cycling
Constructed from robust heavy gauge steel, these headers resist warping and cracking as they heat up and cool down. The substantial wall thickness maintains structural integrity under the extreme pressures generated by a modern small block LS, ensuring that each primary tube holds its designed profile. Expert welding techniques reinforce critical junctions at the merge collector and flange, preventing stress points from developing over time. This rugged build delivers reliable durability for both daily commuting and track use, providing consistent performance without premature distortion.
Precision Machined Flanges and Bolt-on Installation
Each flange is CNC machined to a precise 3/8 inch thickness, guaranteeing a flat mating surface that aligns perfectly with stock exhaust ports. This dimensional accuracy prevents exhaust leaks and eliminates the common need for gasket squish adjustments or additional shimming. Factory-style bolt holes correspond exactly to existing head mounting points, and the included gaskets and stainless steel hardware allow a true bolt-on installation that avoids any cutting or welding. Installers benefit from reduced labor time and can maintain factory clearances for steering and crossmember components without modification.
