Ceramic Coated Long Tube LT Headers for 1973-1987 Chevy/GMC 2WD Trucks
When fitting an LT engine under the frame rails of a 1973 to 1987 Chevy C10 or GMC C15 the exhaust challenge begins with misaligned factory ports that demand grinding or adapter plates. These long tube headers use 1 7/8 inch ceramic coated mandrel bent tubes to clear tight rails while preserving exhaust pulse energy. By matching OEM port geometry with CNC formed flanges and welded oxygen sensor bungs this design ensures a leak free seal without guesswork. A multilayer ceramic finish reflects heat back into the exhaust stream which lowers underhood temperatures and shields wiring and hoses during extended operation.
Precision CNC Flange Geometry for Exact Port Fit
The flanges on these headers are formed by computer controlled machining to match the factory exhaust port profile within thousandths of an inch. At a three eighths inch thickness, the mild steel flanges resist warping under repeated heat cycles and vibration. This exact fit removes the need for port grinding or gasket modifications, creating a leak free seal and preserving exhaust pulse energy. By retaining the original bolt hole pattern, installers can align hardware quickly and avoid time lost to guesswork or rework.
Advanced Ceramic Finish for Controlled Heat Reflection
A multi layer ceramic finish covers each mandrel bent tube to reflect radiant heat back into the exhaust stream, lowering temperatures under the hood and shielding nearby wiring and hoses. By containing thermal energy within the header walls, the coating maintains exhaust pulse velocity for sharper throttle response and optimized torque delivery. This durable barrier also guards against corrosion and abrasive fallout, ensuring consistent performance over years of seasonal exposure. Technicians will appreciate the way reduced underhood heat simplifies sensor placement and routing.
Premium Mild Steel Tubing with Reinforced MIG Welds
Constructed from high quality mild steel, the 1 7/8 inch tubes balance toughness and flexibility under extreme heat stress. Uniform MIG weld beads reinforce each junction, creating smooth interior transitions that minimize flow restrictions and prevent stress concentration points. Unlike brittle joints, these welds accommodate thermal expansion and contraction without cracking or fatigue. Every seam is inspected for consistency, ensuring the headers stand up to spirited driving and daily use alike without compromising durability.
Comprehensive Hardware Kit for Faster LT Swap Installation
This package includes composite exhaust gaskets, high grade bolts, V band clamps and pre welded oxygen sensor bungs, matching mounting points on 1973–1987 Chevy C-10, GMC C-15, and 2WD Blazer, Jimmy and Suburban models. By providing all necessary fasteners and fittings in one box, the kit eliminates last-minute parts hunts and reduces shop downtime. Installers benefit from a straightforward bolt-on process that mirrors original patterns, accelerating project turnaround and letting them focus on tuning rather than sourcing small components.
Engineered to deliver a precise fit and reliable performance for your LT swap.
