1-7/8 inch LT Long Tube Headers for 73-87 C-10/C-15 & 73-91 K5/Jimmy/Suburban

Precision port matching and full ceramic coating on 1 7/8 inch long tube headers delivers a measurable increase in horsepower and torque by optimizing exhaust flow and reducing underhood heat in 1973 to 1987 GM C10, C15 and early K5 two wheel drive Blazer, Jimmy and Suburban models. Pre welded oxygen sensor bungs ensure a leak free seal, while included hardware and gaskets simplify bolt on installation and mild steel construction resists heat fatigue for reliable LT swap performance.

LT Ceramic Coated Headers for 1973-1987 C-10/C-15 & 1973-1991 Blazer K5/Jimmy/Suburban

The 1973 through 1987 2WD GM Truck LT Series 1-7/8 Ceramic Coated Long Tube Headers are built to solve the tight clearance and port mismatch challenges common in LT engine swaps on classic Chevy and GMC rigs. Crafted from mild steel with CNC formed flanges that match factory exhaust ports, these headers ensure a direct seal and include O2 sensor bungs positioned for accurate readings. A ceramic layer reflects heat into the exhaust stream to lower underhood temperature and sustain scavenging for smoother throttle response. Installers will appreciate the complete hardware kit that streamlines fitment into C10, C15, K5 Blazer, Jimmy and Suburban platforms.

Enhanced Exhaust Flow and Pulse Scavenging

The 1.875 inch primary tubes maintain optimal gas velocity and minimize backpressure for improved response. Balanced pulses help to draw exhaust out of the combustion chamber more effectively, boosting mid range torque and smoothing power delivery. The smooth path to the collector reduces turbulence at high rpm, translating into measurable gains in horsepower. This effect is especially beneficial for LT engine conversions that often suffer from port mismatch and tight clearance zones, delivering a more immediate throttle feel under real world conditions.

Effective Heat Control with Ceramic Coating

A multiple layer ceramic finish reflects radiant energy back into the exhaust stream, reducing temperature under the hood and shielding critical wiring and hoses. By keeping heat inside the tubes, the coating preserves the energy of exhaust pulses to support consistent scavenging and throttle response. This surface treatment resists abrasion and cracking through repeated heat cycles, ensuring durability in daily driving or spirited runs. Lower underhood heat also helps keep intake air cooler for more efficient combustion and engine longevity.

Precision Machined Flanges for Secure Sealing

CNC formed flanges are cut and machined to match factory exhaust ports within tight tolerances to ensure a reliable seal. At 3/8 inch thick, they resist warping under thermal stress and vibration, holding composite gaskets firmly in place when torqued with quality fasteners. The precise fit eliminates exhaust leaks that can trigger diagnostic codes or sap performance. Installers benefit from accurate port alignment and a leak free connection on the first attempt, streamlining the swap process and reducing rework.

Robust Mild Steel Body and Strong Welds

These headers are built from premium mild steel to balance toughness with the ability to withstand heat induced expansion cycles. MIG welded beads reinforce every critical joint and provide uniform strength along the tube seams, preventing cracks under demanding conditions. Manufactured in the USA under strict quality controls, each component delivers consistency in fit and finish. The inclusion of composite gaskets, high grade bolts and V band clamps simplifies assembly, allowing installers to focus on tuning rather than sourcing hardware.

Engineered for a precise fit and durable performance under demanding conditions.
