1975-1979 X-Body LS 1-7/8 Ceramic Coated Long Tube Headers
Dropping a modern LS motor into your 1975 to 1979 X-body demands headers that clear frame rails and channel exhaust effectively, and these ceramic coated long tube headers meet that need with precision. Each 1 7/8 inch primary tube is laser-checked for consistent diameter to support smoother pulse tuning and torque delivery across the rev range. Featuring 3/8 inch flanges and a V Band collector, this design maintains a tight seal under high exhaust temperatures. Built for fuss-free LS engine swaps, these headers pair with standard hardware to simplify installation while guarding surrounding components from excessive heat.
Dedicated Precision Fit for 1975 to 1979 X-Body LS Swaps
These headers are laser-verified to maintain a consistent 1 7/8 inch primary tube diameter, a key factor in smooth exhaust pulse tuning and predictable torque delivery. The tubes are carefully routed to clear the frame rails on 1975 to 1979 X-body GM trucks, eliminating clearance headaches during installation. Each 3/8 inch flange is machined flat to guarantee a uniform seal against the cylinder head, preventing exhaust leaks that can sap performance. By matching the exact factory mounting points, these long tube headers deliver a plug-and-play experience that eliminates custom trimming or manifold adapters.
Silver Ceramic Coating for Thermal Management
The silver ceramic finish on each tube and collector delivers superior heat deflection, keeping under-hood temperatures in check and protecting adjacent wiring and hoses. This coating forms a thin, hard barrier that resists oxidation and corrosion even when exposed to sustained high temperature exhaust gases. By reducing radiant heat, the engine bay stays cooler, which can help preserve intake charge density and extend the life of engine components. The clean, reflective surface also maintains a showroom appearance without peeling or blistering over time.
Mild Steel Construction and Flange Integrity
Fabricated from premium mild steel, these headers strike the ideal balance between ductility and strength, allowing the tubing to withstand the thermal cycling common in LS engine applications. Mild steel offers excellent weldability, ensuring that each joint achieves full penetration without compromising tube integrity. The robust 3/8 inch flanges resist warping under extreme exhaust pressure, which is vital for maintaining a leak-free seal over thousands of heat cycles. This durable steel construction also simplifies repair or modification if custom fabrication is ever required.
V-Band Collector for Secure, Leak-Free Connections
The integrated V-band collector replaces traditional slip-fit or bolted flanges, delivering a compact connection that can be quickly assembled or removed for maintenance. A single clamp and precision-machined mating flange create a concentric seal that holds tight under vibration and thermal expansion. This design not only reduces the chances of exhaust leaks but also eases the alignment of downstream components like catalytic converters or mufflers. With the V-band system in place, service intervals become faster and less error-prone, keeping your swap running reliably.
These headers deliver precise fit and reliable performance for your 1975 to 1979 X body LS conversion.
