Ceramic Coated LS Headers Tailored for 1973-87 4WD Trucks

By pairing 1-7/8 inch primaries with a silver ceramic coating, these mid length headers boost horsepower and torque, lower engine compartment heat and resist corrosion. Every 3/8 inch flange and precision-fit design guarantees secure sealing under extreme stress while enabling precise LS engine placement in 1973 to 1987 four wheel drive trucks.

1-7/8 Ceramic Coated Mid-Length Headers for 1973-1987 4WD Truck LS Swap

If you are tackling an LS engine swap in a 1973-1987 four wheel drive truck these ceramic coated headers address underhood heat and scavenging challenges from the start. Built with 1.875 inch primary tubes for optimal pulse overlap and 3/8 inch thick flanges these headers ensure a leak free seal under sustained load while resisting moisture and road salt. Precision cut flanges and CNC formed tubes align perfectly with LS small block and big block ports to simplify installation and preserve clearance around steering components and brake lines. The silver ceramic finish keeps heat inside the tubing and out of the engine bay for more stable intake temperatures on long hauls and spirited drives.

Optimized 1.875 Inch Primaries in Mid Length Headers

These headers employ 1.875 inch primary tubes sized to create an ideal pulse overlap, enhancing exhaust scavenging and gas velocity. By tuning tube diameter to this specification, back pressure is reduced, leading to measurable gains in horsepower and torque across the LS rev range. Drivers will notice stronger low end response, as the system maintains consistent flow under load. This precise tube design makes the most of both small block and big block LS engines, translating directly into more responsive acceleration.

Durable Ceramic Coating for Heat Management and Corrosion Resistance

The silver ceramic finish acts as a thermal barrier that keeps heat inside the tubes and out of the engine bay, helping to maintain cooler intake air temperatures under heavy use. This surface treatment withstands moisture and road salt, preventing rust and preserving the steel substrate over multiple seasons. It also simplifies cleaning by repelling oil and grime, so maintenance stays straightforward. In coastal or humid environments the coating proves especially effective at retaining a fresh underhood appearance.

3/8 Inch Thick Flanges Deliver Reliable Leak Free Sealing

Flanges made from 3/8 inch thick steel plate provide a flat and stable mating surface that resists warping under high exhaust temperatures. Thicker flanges help maintain gasket integrity through repeated heat cycles, ensuring a leak free seal even during sustained engine load. Steel construction adds durability against vibration and flex, which is common in lifted four wheel drive applications. This robust flange design minimizes the need for retorquing and delivers long term sealing performance.

Precision Fit Design Simplifies LS Engine Integration

Each flange and tube section is laser cut and CNC formed to precisely match LS small block and big block exhaust ports, enabling a bolt on fit with minimal adjustment. This level of accuracy reduces installation time and eliminates common clearance issues near steering components and brake lines. Builders can focus on other swap tasks without chasing exhaust leaks or modifying factory mounting points. The result is a clean and dependable integration that preserves vehicle handling characteristics.

These headers deliver a precise fit and reliable sealing to support your LS swap with confidence.
