Ceramic Coated LS 1-7/8 Long Tube Headers for 1955-1957 Chevy Truck
Fitting the 1955-1957 Chevy LS 1-7/8 Ceramic Coated Long Tube Headers into your classic truck tackles two critical challenges at once, aligning the LS engine precisely to the factory frame and managing underhood heat. Each tube follows mandrel bends that preserve internal diameter and balance exhaust pulses, preventing backpressure while matching factory mounts without cutting or reshaping the frame. By reflecting heat back into the exhaust stream, ceramic coating lowers temperatures around wiring and intake parts, and the single clamp collector speeds maintenance with a leak free seal and minimal tools.
Precision Alignment with Mandrel Bends for 1-7/8 Exhaust Flow
Long tube headers rely on mandrel bends to keep the internal diameter consistent from flange to collector. A constant 1-7/8 inch path lets exhaust pulses move without disruption, cutting backpressure and boosting scavenging. By matching original engine mount points and frame rails, these headers fit the 1955 to 1957 Chevy truck stock layout. Installers avoid cutting or reshaping the frame, and cylinder heads see less stress as exhaust ports seal smoothly under heat cycles. This precision fit speeds installation and preserves core engine components over years of use.
Ceramic Coating for Effective Under Hood Heat Shielding
A ceramic layer on each tube acts as a thermal barrier that keeps heat inside the exhaust stream. Reflecting radiant energy away from wiring, fuel lines and intake parts helps prevent heat soak and protects sensitive components. Cooler under hood conditions also maintain denser charge air, which can support consistent power delivery. Over time, the coating limits oxidation, helping steel tubes resist corrosion and retain finish under varied operating demands.
Steel Flanges with 3/8 Inch Thickness for Consistent Seals
Each flange on these headers is cut from 3/8 inch thick steel to deliver a flat, rigid sealing surface. This robust dimension resists warping when exposed to repeated heat expansion and contraction, keeping gaskets compressed evenly against the cylinder head. A stable seal prevents small exhaust leaks that can sap torque and create unwanted noise. Even under vibration or hard launches, the thick flanges maintain contact integrity for reliable performance.
V Band Collector System for Fast Service Access
The V band collector uses a single clamp to join left and right header banks into the mid tube. By applying force around the entire circumference, it replaces multiple bolts and gaskets with one precision clamp and seal. This design makes front end removal or exhaust inspection a quick task with minimal tools. Mechanics can loosen one clamp rather than several fasteners, enabling swift access for routine checks or repairs while keeping leaks at bay.
These headers deliver a precise fit and reliable performance for your LS-powered classic Chevy truck.
