1988-1998 Chevy C/K & GMC Sierra 2WD Ceramic Coated LS Long Tube Headers
The 1988-1998 2WD Truck LS 1-7/8 Ceramic Coated Long Tube Headers were developed to solve the choke points in exhaust manifolds and deliver smooth power gains in classic Chevy C/K and GMC Sierra pickups. Featuring precisely measured 1-7/8 inch primary tubes and a durable ceramic coating these headers reduce underhood heat and support improved airflow. Each header is shaped to accommodate LS engine mounts and maintain clearance around brake lines and steering components. Built to last these mild steel headers ensure a reliable seal and consistent performance under high exhaust pressures.
Precision Engineered Fit for LS Engine Mounting
The headers are designed with flanges precisely aligned to LS cylinder head ports and truck engine mounts, eliminating the need for flange spacers or adapter plates. This exacting fit not only slashes installation time but also ensures each primary tube seals uniformly against the head surface, preventing exhaust leaks at the very first startup. By matching OEM mounting points, the system maintains proper alignment with steering and brake lines, preserving original chassis clearances. Installers benefit from a more predictable process and a reliable outcome without additional trimming or modifications.
Improved Scavenging through 1-7/8 Inch Tubing
Each primary tube measures 1-7/8 inches in diameter, striking an ideal balance between gas velocity and flow capacity for street and light performance use. The consistent diameter and mandrel bends encourage even exhaust scavenging across all cylinders, which translates directly into stronger midrange torque and improved top-end horsepower. Collector pulses merge smoothly thanks to the included V-band clamp, sustaining exhaust velocity and reducing turbulence. As a result, throttle response feels sharper and power delivery is noticeably more linear when accelerating.
Ceramic Coating for Underhood Temperature Control
The ceramic barrier coating reflects radiant heat back into the exhaust stream, cutting down temperatures under the hood by as much as 50 percent compared with bare metal headers. Cooler bay temperatures safeguard intake components, wiring harnesses, and brake lines from heat soak, while enhancing air-charge density for better combustion. This thermal protection extends the life of both the header and nearby engine parts by resisting oxidation, corrosion, and abrasive contaminants. Over time, the coating maintains its integrity to ensure ongoing heat management in demanding environments.
Heavy Duty Steel Construction with Flange Strength
Crafted from robust mild steel, these headers endure repeated heat cycles and vibration without warping or cracking. The 3/8 inch thick flanges hold their flatness even at extreme exhaust pressures, ensuring a leak free seal against the cylinder head gasket. Steel mandrel bends retain consistent cross-sectional area for dependable performance, while the integrated V-band collector makes service and future disassembly quick and straightforward. Together, these design choices deliver a durable header system built to withstand the rigors of truck duty.
