LT Long Tube Headers for 1973-1987 C-10/C-15 and 1973-1991 2WD Blazer K5 Jimmy Suburban
When fitting an LT motor into a 1973-1987 C10 or K5 Blazer chassis, exhaust clearance and port mismatch can stall any swap plan. Built from premium mild steel with CNC formed flanges that mirror factory ports, these 1 7/8 inch ceramic coated long tube headers deliver a precise seal and include pre welded O2 bungs for accurate sensor readings. The multi layer ceramic finish reflects heat inward to reduce underhood temperatures and safeguard nearby wiring while maintaining pulse energy for a more responsive throttle feel. Installers benefit from a complete hardware kit that simplifies bolt on fitment across C10, C15, Blazer K5, Jimmy and Suburban models, eliminating last minute parts hunts.
Precision CNC Formed Flanges for Leak Free Alignment
Computer controlled machining ensures each flange matches the factory exhaust port profile within thousandths of an inch, producing a reliable seal without the need for grinding or filler. At a robust three eighths of an inch thick, these mild steel flanges resist warping under heat cycles and vibration, preserving gasket integrity over time. The precise port to tube interface eliminates alignment error that often leads to exhaust leaks, misfires, and fault codes. Installers can rely on consistent hole patterns that line up with original bolt points, cutting out trial and error and speeding up the swap process.
Effective Heat Management with Ceramic Coated Tubes
A multi layer ceramic finish reflects radiant heat back into the exhaust stream to lower underhood temperatures and protect electrical wiring, hoses, and intake components. By containing thermal energy within the tubes, the ceramic surface helps sustain pulse velocity and scavenging action for a more responsive throttle feel. This coating also offers abrasion and corrosion resistance, guarding against flaking or cracking during long term operation. The result is a cooler engine bay, which can improve component longevity and maintain consistent performance under load.
Mild Steel Construction Reinforced by MIG Welded Joints
Constructed from premium grade mild steel, these headers balance toughness with the ability to absorb expansion and contraction during heat cycles without cracking. Uniform MIG weld beads reinforce every junction, creating smooth interior transitions that minimize flow restrictions and prevent stress concentrations. Weld quality is critical to avoid failures in high temperature areas, and each joint undergoes inspection to ensure structural integrity. The material choice delivers reliable performance in daily driving, while the welds stand up to repeated thermal stress encountered during spirited operation.
Complete Hardware Kit for Bolt-On Installation
Each header comes with composite gaskets, high grade bolts, V band clamps, and pre welded O2 sensor bungs, providing everything needed for a straightforward swap. By including all fasteners and fittings in one package, installers avoid parts runs and lost time searching for compatible components. The layout mirrors factory mounting points, and the pre fitted sensor locations help ensure accurate exhaust monitoring right out of the box. With this kit, technicians can focus on fine tuning rather than hunting for missing pieces, making the installation process faster and more reliable.
