1968-1972 A-Body 1-7/8 Ceramic Coated LS Mid-Length Headers
When fitting an LS engine into a 1968-1972 A-Body chassis, precise routing around frame rails and suspension is vital and these 1 7/8 inch ceramic coated mid length headers deliver that exact fit. Each mandrel bent tube follows the stock contours to maintain clearance without modifying your frame and the reflective silver ceramic shell holds exhaust heat within the runners to lower underhood temperatures. Thick 3/8 inch flanges are machined flat for a reliable seal and align perfectly with LS head bolt patterns. Installers appreciate a bolt in solution that stands up to daily driving and spirited track use.
Precision Steel Tube Design for 1965 through 1970 B Body LS Conversion
The primary tubes are mandrel bent from robust steel to follow the unique contours of 1965 through 1970 B Body chassis rails, ensuring a precise fit that clears suspension components without modification. By maintaining true center-to-center spacing across all cylinders, stress is evenly distributed along the head flange, preserving gasket life through repeated heat cycles. The 1 7/8 inch diameter optimizes exhaust velocity and pulse tuning, which translates directly into stronger torque at low rpm and measurable horsepower gains at higher revs. Weld beads are ground smooth to eliminate flow disruptions, and the seamless tube design resists cracking under thermal stress. Installers gain confidence from a component that aligns exactly with LS head bolt patterns for a hassle-free engine swap.
Silver Ceramic Coating for Effective Heat Management
A reflective ceramic shell covers each primary tube, trapping radiant heat within the exhaust stream and reducing underhood temperature by as much as 100 degrees Fahrenheit. This thermal barrier protects wiring, hoses, and other heat-sensitive components around the engine bay, extending service life and simplifying maintenance. Retained heat also accelerates catalytic converter light-off, improving emissions performance on street-driven vehicles. The coating resists abrasive deposits and prevents corrosive buildup, so the headers maintain a clean, polished appearance over many seasons. Beyond aesthetics, this surface treatment supports improved scavenging at midrange rpm, yielding a more responsive throttle feel during daily driving or spirited acceleration.
Machined 3/8 Inch Flanges for Leak Free Sealing
Flanges milled from solid steel plate maintain a consistent thickness of 3/8 inch to eliminate warpage and ensure even gasket compression across all exhaust ports. Precision CNC machining of the flange faces guarantees an exact match to LS head openings, removing the need for shims or spacers during installation. The increased material mass dampens vibration and resists distortion under high manifold pressures, securing a leak free seal even when the engine is pushed hard on track or on long hauls. Bolts line up perfectly with LS pattern threads, cutting setup time and reducing the risk of exhaust leaks that can sap performance and raise underhood sound levels. This attention to sealing integrity ensures reliable operation season after season.
These ceramic coated headers deliver precise fit and reliable heat management for your LS engine conversion.
