Ceramic Coated 1-7/8 LS Mid-Length Headers for 1973-1987 4WD Trucks
Tailored to the rigors of an LS engine swap in a 1973-1987 4WD truck this set of ceramic coated headers focuses on improving power delivery and mitigating underhood heat. With 1-7/8 inch primary tubes calibrated for optimal exhaust scavenging these headers deliver measurable gains in horsepower and torque across small block and big block LS platforms. The robust ceramic finish limits heat transfer into the engine bay while standing up to corrosion from moisture and road salt. Precision flanges and an accurate fit make installation straightforward and preserve exhaust sealing under high stress for reliable operation.
Engineered 1-7/8 Inch Primaries for Superior Exhaust Scavenging
These mid length headers employ 1-7/8 inch primary tubes that are carefully sized to create an ideal pulse overlap and scavenging effect. By tuning tube diameter to this specification, exhaust gases exit with higher velocity, reducing back pressure and boosting both horsepower and torque across the rev range. Enthusiasts will notice stronger low-end response and more immediate throttle reaction as the system maintains consistent flow even under heavy load. This dynamic approach to tube sizing translates directly into a more engaging driving experience for your 1973-1987 four-wheel drive truck.
Ceramic Coating Offers Thermal Control and Corrosion Resistance
The silver ceramic finish acts as a thermal barrier that limits heat soak into the engine bay, helping maintain cooler intake temperatures and prolonging component life. Beyond managing underhood heat, the coating provides a tough outer layer that stands up to moisture, road salt and humid coastal conditions without flaking or peeling. This surface treatment also simplifies cleanup by repelling oil and grime. As a result, you preserve engine-bay aesthetics and protect the steel substrate against rust over many seasons of use.
3/8 Inch Flanges and Steel Build for Reliable Sealing
Constructed from robust steel with 3/8 inch flanges, these headers deliver a flat, stable sealing surface that resists warping under high exhaust temperatures. The extra flange thickness absorbs heat cycles without compromising gasket integrity, ensuring a leak-free exhaust path even during sustained operation. Steel tubing offers a cost-effective and durable backbone, capable of withstanding road vibration and flex common to lifted four-wheel drive trucks. This combination of material strength and flange rigidity guarantees long-term performance without the need for frequent retorquing.
Precision Fit Design Simplifies LS Engine Integration
Every flange and tube joint is laser cut and CNC formed to match the exhaust ports of LS small block and big block engines, delivering plug-and-play alignment. This precision approach reduces installation time and eliminates common fitment issues, so builders can focus on wiring, plumbing and tuning instead of chasing exhaust leaks. The straightforward bolt-on configuration maintains factory mounting points and preserves clearance to suspension links, brake lines and steering components. As a result, the swap process remains clean and hassle-free.
Provides a precise fit and dependable performance for your LS swap.
