1963-1972 LT Ceramic Coated Long Tube Headers for GM C-10 C-15 Blazer K5 Jimmy Suburban
Swapping an LT engine into a classic Chevy C-10 or GMC C-15 chassis often exposes misaligned ports and drives underhood temperatures skyward; the 1963-1972 GM Truck LT Series 1-7/8 Ceramic Coated Long Tube Headers address these challenges with precision CNC flanges and a ceramic-coated finish that reflects radiant heat. Equipped with smooth mandrel bends and constant-diameter tubes, this header set simplifies installation on C-10, C-15, Blazer K5, Jimmy and Suburban models while promoting consistent exhaust scavenging and stronger midrange torque. Installation is further streamlined by included composite gaskets and premium hardware, and the mild steel tubes with expert MIG welding resist fatigue during thermal cycling and daily driving conditions. By retaining exhaust gas velocity inside the tubes, the design maximizes scavenging efficiency without the need for bulky shields beneath the hood.
Streamlined LT Exhaust Flow with Constant Diameter Tubing
The 1 7/8 inch tubes feature smooth mandrel bends that preserve a uniform interior profile from the head port to the collector, keeping exhaust pulse energy intact through each turn. By matching runner lengths precisely, this design promotes consistent scavenging across all cylinders, resulting in stronger midrange torque and a more responsive throttle feel. Turbulence is minimized at each bend so gases flow without interruption, reducing backpressure and improving overall engine efficiency. This approach also prevents hot spots in thin wall sections, enhancing tube longevity during thermal cycling. By preserving exhaust pulse energy, the system delivers reliable performance from idle to highway speeds.
Layered Ceramic Finish for Under Hood Temperature Control
The layered ceramic coating acts as an effective heat barrier by reflecting radiant energy back into the exhaust gases, maintaining higher flow temperatures and accelerating gas velocity. This thermal management protects critical under hood components such as wiring harnesses, fuel lines and linkages from premature heat damage. Drivers will notice lower bay temperatures that support consistent performance during extended operation or heavy load conditions. After cure the coating stands up to abrasion and resists fading even after extended exposure to heat cycles. The result is a cleaner engine bay and reduced risk of heat soak in high ambient environments.
Precision Flange Machining and Gasket Seal Assurance
CNC machining of the 3/8 inch flanges ensures exact head port alignment and a flawless mating surface for each cylinder bank. Composite gaskets conform to subtle surface irregularities while maintaining clamp force under repeated thermal cycles, preventing exhaust leaks that can sap power or trigger noise concerns. High grade bolts and V band clamps secure the header and collector with consistent torque retention, eliminating the need for retightening. Included composite gaskets and premium hardware complete the package and reduce assembly time by ensuring proper sealing from the start. A leak free connection preserves engine output and supports reliable emissions control.
MIG Welded Mild Steel Tubes Deliver Structural Integrity
Premium mild steel tubes are formed from domestic stock with uniform wall thickness to resist fatigue under constant thermal stress. Expert MIG welding creates smooth bead profiles that stand up to repeated heat cycles and engine vibration without cracking. Each weld joint is inspected to confirm full fusion and to support long term durability under heavy load conditions. This construction method yields consistent quality from unit to unit and supports both daily driving and sustained high load operation. Consumers can rely on this robust construction to handle the demands of spirited driving or towing heavy loads without fatigue.
Engineered for a precise fit and enduring performance this header set offers consistent torque gains and reliable durability.
