LT Long Tube Headers for 1963-1972 Chevy GMC Trucks C-10 C-15 K5 Blazer Jimmy Suburban
When starting an LT engine swap in a classic 1963 to 1972 Chevy C 10 or GMC C 15 chassis precise exhaust routing and underhood heat control are critical and these long tube headers address both requirements with optimized runner length and port alignment. Crafted from premium mild steel with CNC formed flanges and integrated O2 sensor bungs installers get a leak free seal along with consistent torque retention. A multi layer ceramic finish manages radiant heat by reflecting it back into the exhaust stream lowering underhood temperature and preserving wiring and components during sustained runs. These headers are engineered for a direct fit on Chevy C 10 1963 to 1972 trucks along with Blazer K5 two wheel drive Jimmy and Suburban models ensuring straightforward installation even in tight engine bays.
Precision Runner Layout for Enhanced LT Exhaust Scavenging
These headers feature 1 7/8 inch diameter tubes that extend deep into the engine bay, aligning precisely with LT engine port spacing to optimize exhaust pulse timing. The deliberate separation of each tube promotes effective pulse separation, which draws spent gases from the combustion chamber with greater efficiency. Efficient scavenging at both midrange and high rpm delivers noticeable improvements in torque and a more responsive throttle feel on classic Chevy C 10 and GMC C 15 models. Crafted mandrel bends reduce turbulence, preserving smooth flow across the rev band. Matching runner length to cylinder exhaust timing ensures maximum energy extraction from each pulse without compromising strength.
Layered Ceramic Finish for Effective Thermal Management
A proprietary layered ceramic coating reflects radiant heat back into the exhaust stream, lowering underhood temperatures and protecting adjacent wiring and components during sustained operation. By acting as a thermal barrier, the finish reduces heat soak into critical engine bay areas, which enhances component life and avoids heat related failures. The coating is cured to resist abrasion and maintain integrity through repeated heating cycles, ensuring a consistent surface over time. In addition to thermal control, the finish promotes faster engine warmup and improves exhaust velocity, further boosting scavenging and overall efficiency. This approach streamlines temperature management and supports reliable performance in demanding conditions.
CNC Formed Flanges for Precise Exhaust Sealing
Each flange is formed using CNC equipment to maintain an exact 3/8 inch thickness that aligns perfectly with factory engine ports. When paired with composite gaskets and supplied hardware the tight tolerances prevent exhaust leaks and avoid noise issues commonly encountered with loose connections. Installers benefit from straightforward torque procedures that deliver consistent clamp load and resist loosening under vibration. This precise mating surface supports minimal backpressure and ensures steady exhaust flow, which contributes to the headers' reliable gains in power. Controlled thermal expansion further reduces retightening needs after initial break in, saving time and effort.
Premium Mild Steel Tubing with Expert MIG Welding
Constructed from domestic mild steel with uniform wall thickness these headers withstand extreme heat and mechanical stress without cracking or warping. Expert MIG welding creates strong, consistent weld beads that can endure numerous thermal cycles, assuring structural integrity over time. The tubing's resilience to fatigue makes it suitable for daily driving and spirited runs, providing dependable service life and performance. All fabrication takes place under strict quality standards in the USA, ensuring each header meets precise tolerance requirements before shipping. The combination of robust materials and skilled workmanship results in a durable assembly built to support demanding engine swaps.
Engineered for a direct fit and dependable performance in your LT engine swap project.
