Ceramic Coated 1-7/8in LS Long Tube Headers for 1988-1998 Chevy/GMC C/K 2WD Trucks
Builders installing an LS in a classic Chevy or GMC two wheel drive truck built between 1988 and 1998 rely on precise long tube headers to clear brake hard lines and steering gear while enhancing exhaust scavenging. These ceramic coated primaries are mandrel bent to match factory frame rails and seal directly to LS cylinder head ports without spacers or adapter plates. The ceramic barrier coating traps radiant heat within the exhaust stream and lowers underhood temperatures to shield intake components, wiring harnesses, and brake lines from heat soak. Made from mild steel with thick flanges and a secure collector clamp this header set delivers a reliable seal under high exhaust pressures and endures repeated heat cycles on demanding applications.
Precision Fit Headers for LS Swap Installations
These headers are crafted with flanges that align exactly to the port dimensions of LS cylinder heads, eliminating the need for spacers or adapter plates. That precise alignment ensures each primary tube mates flush to the engine block, preventing exhaust leaks from the moment of first startup. By matching factory frame rail contours, the design maintains ample clearance around brake lines and the steering box, so no trimming or rerouting is required. Installers benefit from a streamlined process and predictable results, saving time and reducing the risk of errors during assembly.
Ceramic Barrier Coating for Thermal Control
A heat resistant ceramic barrier layer reflects radiant energy back into the exhaust stream, which can lower underhood temperatures by as much as 50 percent compared with bare steel. Lower bay heat helps protect intake runners, wiring harnesses and brake hoses from heat damage, supporting consistent air charge density and reliable performance. This coating also resists oxidation and corrosive elements, maintaining its integrity through repeated heat cycles. Over time that durable finish ensures ongoing temperature management without peeling or flaking.
Smooth Exhaust Scavenging with Mandrel Bends and V Band Collector
The mandrel bent 1.875 inch primary tubes maintain a uniform cross sectional area through each curve, reducing turbulence and promoting even pulse timing. As exhaust pulses merge in the V band collector, the design sustains optimal velocity and minimizes backpressure at high rpm. The V band clamp provides a secure yet service friendly joint, allowing quick disassembly for maintenance or performance upgrades. Together, these features translate into sharper throttle response, stronger midrange torque and a more linear power curve.
Heavy Duty Steel Construction for Reliable Sealing
Manufactured from robust mild steel, these headers are built to withstand the thermal expansion and vibration common to truck applications. The 3/8 inch thick flanges retain their flatness under extreme exhaust pressure, ensuring a tight seal against the head gasket and preventing leaks. Thick wall tubing stands up to repeated heat cycling without warping or cracking, while the V band joint simplifies future repairs or system changes. This rugged construction delivers dependable performance mile after mile.
