Ceramic Coated 1-7/8 LT Long Tube Headers for 1963-1972 C-10, C-15, K5 Blazer/Jimmy and Suburban
Retrofitting an LT engine into a classic 1963 through 1972 Chevy C-10, GMC C-15 or Suburban chassis can expose mismatch in tube length and flange spacing but these 1963 through 1972 GM Truck LT Series 1.875 inch Ceramic Coated Long Tube Headers solve that by pairing CNC formed 3/8 inch flanges with mandrel bends that match factory port layout. Built in O2 sensor ports and included mounting hardware assure simple hookup and secure fit in Chevy C-10, GMC C-15, K5 Blazer, Jimmy and Suburban 2WD models. The multilayer ceramic finish reflects heat back into the exhaust stream to lower underhood temperatures and shield wiring and linkages from damage. With identical tube lengths and uniform diameter, each header yields optimized exhaust scavenging for a stronger midrange response and dependable performance during spirited runs.
Mandrel Bent 1.875 Inch Tubing for Enhanced Exhaust Scavenging
The long tube layout with 1.875 inch diameter runners uses mandrel formed bends to preserve a constant cross section and maximize exhaust pulse energy. Each smooth radius bend minimizes turbulence and allows gases to exit combustion chambers more efficiently. This configuration equalizes tube lengths, which is critical for generating a reliable scavenging effect across midrange rpm and improves throttle response in spirited driving. By maintaining a uniform flow area from cylinder head to collector, backpressure is reduced and power delivery remains consistent. The result is stronger low end torque and a balanced power curve without sacrificing everyday drivability on classic Chevrolet and GMC trucks.
Multi Layer Ceramic Coating for Underhood Temperature Control
A proprietary multi layer ceramic finish serves as an effective thermal barrier by reflecting heat back into the exhaust stream and keeping underhood temperatures in check. This heat control protects wiring harnesses, fuel lines and steering linkages from damage during sustained operation. The cured coating resists abrasion and stands up to repeated heating cycles without flaking or fading. By retaining heat within the tubes, exhaust gas velocity is increased, further boosting scavenging efficiency. Installers and drivers alike benefit from a cooler engine bay that aids consistent performance and component longevity.
Precision CNC Flanges and Durable Mild Steel Fabrication
Each flange is CNC machined to a precise 3/8 inch thickness for an exact match to factory cylinder head ports and to ensure a leak resistant seal. The included composite gaskets and high grade bolts deliver correct clamp load so fasteners stay secure under constant vibration and thermal expansion. Tubing is crafted from domestically sourced mild steel with uniform wall thickness for strength and fatigue resistance. Expert MIG welding produces clean, uniform beads that resist cracking through countless heat cycles. Together, these features guarantee a dependable installation and long service life for your LT engine swap.
