Ceramic Coated LT Long Tube Headers for 1963-1972 GM C-10 C-15 Blazer K5 Jimmy Suburban
Retrofitting an LT engine into a 1963-1972 Chevy C-10 or GMC C-15 chassis demands headers that align port spacing, manage radiant heat and maintain a leak-free seal under vibration. These 1963-1972 GM Truck LT Series 1-7/8 Ceramic Coated Long Tube Headers deliver that precise fit by pairing CNC formed flanges with 1.875 inch mandrel bends to optimize pulse timing and minimize backpressure. A multi layer ceramic finish reflects heat back into the exhaust stream, lowering underhood temperatures and protecting wiring and steering linkages during sustained runs. Built in O2 sensor bungs and an installer focused design ensure straightforward mounting in Chevy C-10, GMC C-15, Blazer K5 two wheel drive, Jimmy and Suburban models so you can complete your swap without custom fabrication.
Optimized 1-7/8 Inch Tubing for Enhanced LT Exhaust Scavenging
The 1-7/8 inch diameter long tube layout is calibrated to match LT engine port spacing, creating an effective scavenging effect at midrange and high rpm. With CNC formed mandrel bends, each runner maintains a uniform cross section that reduces turbulence and preserves exhaust pulse energy. This precise configuration draws spent gases from the combustion chamber more efficiently, translating into stronger low-end torque and a more responsive throttle feel on classic Chevrolet and GMC trucks. By equalizing runner length and minimizing flow restriction, the design maximizes horsepower gains without sacrificing drivability in daily use. The result is a balanced powerband that extracts the most energy from each exhaust pulse across the rev range.
Multi Layer Ceramic Coating and Thermal Management
A proprietary multi layer ceramic finish serves as an effective thermal barrier by reflecting heat back into the exhaust stream rather than allowing it to radiate into the engine bay. This reflection lowers underhood temperatures, protecting sensitive wiring, fuel lines and steering linkage components during sustained operation. The cured coating resists abrasion and maintains its integrity through repeated heating cycles, ensuring consistent performance over time. By helping the engine reach optimal operating temperature more quickly, the finish also improves exhaust gas velocity, further enhancing scavenging efficiency. Altogether, this approach delivers controlled heat and supports reliable function in demanding road or towing scenarios.
Precision 3/8 Inch CNC Formed Flanges for Seal Integrity
Each flange is machined to a consistent 3/8 inch thickness using CNC equipment, which ensures perfect alignment with factory cylinder head ports. When used with the included composite gaskets and high-grade bolts, these flanges create a leak-resistant mating surface that stays secure under constant vibration. Installers will find that consistent torque procedures yield reliable clamp loads without the need for frequent retightening after thermal cycling. This tight seal reduces backpressure and prevents exhaust leaks that can rob power and generate unwanted noise. Controlled thermal expansion at the flange interface further supports steady performance over the life of the headers.
Premium Mild Steel Tubing with MIG Weld Beads
Constructed from domestically sourced mild steel with uniform wall thickness, these headers deliver both strength and flexibility under thermal stress. Expert MIG welding provides robust, uniform weld beads that endure numerous heat cycles without cracking or warping. The inherent fatigue resistance of the tubing material and the precision welds combine to offer long term durability well suited for daily driving or spirited highway runs. All fabrication is performed in the USA under stringent quality controls, guaranteeing that each header meets exact tolerances before it ships. This marriage of quality materials and skilled workmanship results in a dependable exhaust solution for your LT swap project.
