LT Ceramic Coated Long Tube Headers for 1963-1972 Chevy C-10/GMC C-15, 1969-1972 Blazer K5 2WD, 1970-1972 Jimmy 2WD and 1963-1972 Suburban 2WD
Swapping an LT series engine into a 1963-1972 C-10 or C-15 chassis often reveals misaligned exhaust outlets and rising underhood heat; the 1963-1972 GM Truck LT Series 1-7/8 Ceramic Coated Long Tube Headers address these challenges with 3/8 inch flanges machined by CNC for precise port alignment and a multi layer ceramic finish that reflects radiant heat. Fabricated from mild steel tubing with smooth mandrel bends and MIG welded beads, this header set includes O2 sensor bungs, composite gaskets, high grade bolts and V band clamps to deliver consistent exhaust scavenging and stronger midrange torque across idle and highway operation. Each MIG welded bead is inspected to confirm full fusion and support long term durability under daily driving and towing demands.
Precision Design and Diameter Specification
The 1963 through 1972 GM Truck LT Series headers feature a 1.875 inch tube diameter in a long tube layout that promotes smooth exhaust flow and improved engine breathing. By extending the primary pipe length, these headers deliver a balanced backpressure profile that enhances low rpm torque and sustains high rpm power. This design yields a noticeable improvement in throttle response and overall drivability, maximizing the LT engine's output across its full powerband.
Advanced Coating and Material Quality
Each header is treated with a multi layer ceramic barrier that insulates heat within the tubing walls while reducing external underhood temperatures. This coating helps maintain consistent exhaust gas velocities by limiting heat loss, which in turn supports stronger scavenging effects. The result is a stable temperature environment that protects nearby components and preserves precious underhood space, all while reinforcing long term surface integrity against corrosion and thermal fatigue.
Flange Integrity and Welding Excellence
The flanges are machined from 3/8 inch thick plate to ensure a flat, distortion resistant sealing surface that mates precisely to the factory exhaust ports. CNC formed profiles guarantee uniformity from one flange to the next, delivering a leak resistant joint with no need for repeated tightening. Premium mild steel tubing pairs with consistently precise MIG welded beads, offering a robust structure that stands up to thermal cycling and the stresses of daily driving or spirited track use.
Optimized Performance and Chassis Integration
These headers are engineered to work seamlessly with MuscleRods mounting hardware, ensuring proper engine placement and ideal drivetrain angles in GM truck restorations and custom projects. Tuned to support even exhaust scavenging, the design fosters uniform pulse separation for consistent performance gains. Made in USA construction underscores a commitment to quality and reliability, delivering a finished header set that fits precisely, bolts up cleanly, and performs dependably mile after mile.
Precision fit and ceramic barrier coating ensure reliability and consistent performance in your LT swap project.
