LT Ceramic Long Tube Headers for 2WD C-10/C-15 (1973-1987) and Blazer/Jimmy/Suburban (1973-1991)
Adapting an LT engine to a 1973 to 1987 Chevy C10 or GMC C15 requires precision fitment to clear tight frame rails. The 1973-1987 2WD GM Truck LT Series 1-7/8 Ceramic Coated Long Tube Headers employ CNC formed flanges machined from 3/8 inch mild steel to match factory ports and seal without adapters. A multilayer ceramic finish reflects heat away from firewall components and preserves pulse energy. Reinforced MIG weld beads join each mandrel bent tube, while composite gaskets, high grade bolts, V band clamps, and welded O2 sensor bungs are all included. A mount kit for LT engine applications engineered for integration with MuscleRods engine mount kits fits C10, C15, Blazer, Jimmy, and Suburban 2WD models.
Flow Optimization and Power Gains
The one and seven eighths inch long tube architecture in these headers is designed to enhance exhaust scavenging and minimize backpressure throughout the rpm range. By extending primary tubes beyond the cylinder head and merging them into a smooth collector, these headers promote efficient gas evacuation and deliver noticeable torque in the low end and strong horsepower in the midrange. Premium mild steel construction, combined with expertly applied MIG welded beads, ensures structural integrity under repeated thermal cycling. Made in USA, this system provides a direct bolt-up solution that preserves firewall clearance and maintains factory forward accessory drive alignment.
Heat Management and Durability
A multi layer ceramic coating covers each tube to inhibit heat transfer and reduce underhood temperatures. This thermal barrier safeguards sensitive wiring, fuel lines and brake components, while allowing catalytic devices downstream to reach optimum temperature faster. CNC formed three eighths inch thick flanges mirror factory port geometry, ensuring a leak-free seal without gasket blowout. The coating also resists corrosion and abrasion, giving these headers extended service life even in harsh weather. Together, material choice and precise manufacturing guarantee consistent performance over long drives and repeated start-stop cycles.
Precision Fit and Engine Integration
Specifically engineered for LT engine swaps in 1973 through 1987 GM two-wheel-drive trucks, these headers integrate seamlessly with MuscleRods mounts. This partnership ensures proper engine placement and optimal driveline angles, reducing vibration and stress on u-joints and transmission input shafts. The result is a smoother power delivery and increased reliability under load. Because the bolt-in design follows factory mounting points, installation remains straightforward, requiring no frame modification or aftermarket brackets. Each set is backed by rigorous quality control to meet the demands of custom builds and daily drivers alike.
Trust these headers to deliver reliable fitment and consistent power for your LT swap, backed by MuscleRods quality and engineered durability.
