1-7/8 Ceramic Coated LT Long Tube Headers for 1963-1972 Chevy C-10/C-15/Blazer K5/Jimmy/Suburban
Swapping an LT power plant into a 1963 to 1972 Chevy C 10, GMC C 15 or Suburban chassis can expose misaligned ports and excessive underhood heat that hinder performance. These 1963 1972 GM Truck LT Series 1 7/8 Ceramic Coated Long Tube Headers pair CNC formed flanges with smooth mandrel bends to match factory head ports and simplify installation on C 10, C 15, K5 Blazer, Jimmy and Suburban models. The design equalizes tube lengths for reliable exhaust scavenging and stronger midrange response. A multilayer ceramic coating reflects heat back into exhaust flow to protect wiring and keep the engine bay cooler.
Constant Diameter Mandrel Tubing for Optimized Exhaust Scavenging
The smooth mandrel bends of the 1 7/8 inch tubes maintain a uniform interior profile that preserves exhaust pulse energy. By matching each runner to identical lengths from head port to collector, this design achieves consistent scavenging across all cylinders. Turbulence is minimized at each turn so gases flow without interruption and back pressure is reduced. The outcome is stronger torque in the mid range and a responsive throttle feel that suits both daily driving and spirited runs. Engine builders will note that a consistent runner profile prevents hot spots and stresses that could distort thin wall sections during thermal cycling.
Multi Layer Ceramic Finish for Underhood Temperature Management
A proprietary multi layer ceramic finish forms an effective heat barrier by reflecting radiant energy back into the exhaust flow. This thermal control keeps critical engine bay components such as wiring harnesses, fuel lines and linkages safe from excessive heat. By retaining higher temperatures inside the runners, exhaust gas velocity increases which further enhances scavenging efficiency. Drivers benefit from lower underhood temperatures that support consistent performance over extended operation. Once cured the coating resists abrasion and resists fading even after repeated temperature swings.
Precision CNC Flanges and Composite Gasket Seal Integrity
CNC machining ensures each three eighth inch flange matches factory head port spacing for a precise fit and reliable seal. Composite gaskets included in the hardware kit conform to surface irregularities and maintain clamp force even under repeated thermal cycles. High grade bolts and V band clamps secure the header to the head and collector without loosening from vibration. A tight seal prevents exhaust leaks that can sap power and lead to noise or emission issues. Bundled fasteners and clamps streamline the installation process by eliminating trips to hardware stores.
Robust Mild Steel Construction with Expert MIG Welding
The header tubes are formed from domestically sourced mild steel with consistent wall thickness for strength and fatigue resistance. Expert MIG welding creates smooth bead profiles that resist cracking during repeated heat cycles and engine vibration. This construction approach delivers long lasting durability and supports daily duty as well as sustained high load conditions. Each header is assembled and coated in the USA under strict quality standards to ensure consistent performance from unit to unit. Consumers can expect dependable operation mile after mile regardless of driving style or environment.
Engineered for a precise fit and durable performance in any LT swap project.
