Ceramic Coated LT Long Tube Headers for 1973-1987 C-10/C-15 and 1973-1991 Blazer Jimmy Suburban 2WD
When fitting an LT engine under the hood of a 1973 to 1987 Chevy C10 or 2WD Blazer chassis, tight frame rails and port misalignment can stall any swap plan. These 1 7/8 inch ceramic coated long tubes tackle that challenge by matching factory exhaust ports with CNC formed flanges and pre welded O2 bungs for precise sensor placement. Temperature management comes from a multi layer finish that reflects radiant heat back into the exhaust stream to lower underhood temperatures and protect wiring and hoses. Technicians will value the complete hardware kit that mirrors original bolt patterns for a straightforward fit and quicker project turnaround.
Precision CNC Flange Design Ensuring Exact Port Alignment
The flanges on these LT headers are formed by computer controlled machining to match the factory exhaust port profile to within thousandths of an inch. At a three eighths inch thickness, the mild steel flanges resist warping under repeated heat cycles and highway vibration. This exact fit creates a leak free seal without the need for grinding, filler or gasket modifications. By preserving the original bolt hole pattern, installers benefit from straightforward hardware alignment and a predictable swap procedure that eliminates time lost on trial and error adjustments.
Multi Layer Ceramic Coating for Enhanced Heat Management
A proprietary multi layer ceramic finish covers every tube to reflect radiant heat back into the exhaust stream, lowering temperatures under hood and safeguarding nearby wiring, hoses and intake components. By containing thermal energy within the header walls, the coating sustains exhaust pulse velocity and scavenging, translating into a sharper throttle response and optimized torque delivery. The ceramic layers also provide a durable barrier against corrosion and abrasive fallout, ensuring the finish remains intact through seasonal changes and road debris exposure.
Premium Mild Steel Tubing with Reinforced MIG Welds
Constructed from high quality mild steel, these long tubes strike the ideal balance between toughness and flexibility under heat stress. Uniform MIG weld beads reinforce every junction, creating smooth interior transitions that minimize flow restrictions and prevent stress concentration points. Unlike brittle weld types, these joints accommodate thermal expansion and contraction without developing cracks or fatigue. Each weld seam undergoes strict inspection to meet endurance demands of spirited driving and daily use alike.
Complete Hardware Package Simplifying LT Swaps
Included in the kit are composite exhaust gaskets, quality bolts, V band clamps and pre welded oxygen sensor bungs, providing the critical components needed for a full installation. This comprehensive package mirrors original mounting points on 1973–1987 C-10, C-15 and 2WD Blazer, Jimmy and Suburban models, so technicians can tackle the swap without late-stage parts hunts. By delivering all fasteners and fittings in one box, the hardware kit reduces shop downtime and lets installers focus on tuning rather than sourcing hard-to-find pieces.
Engineered for a precise fit and dependable performance in your LT swap, these headers deliver lasting reliability on every ride.
