1-7/8 LS Mid-Length Ceramic Coated Headers for 1988-1998 4WD Trucks
Swapping an LS engine into a 1988 to 1998 GM four wheel drive truck demands exact fit and smooth exhaust flow the 1988-1998 4WD Truck LS 1-7/8 inch ceramic coated mid length headers answer that call with precise port alignment and a heat reflecting ceramic shell. Installation is straightforward thanks to GM specific flanges and routing designed to clear the suspension leaving you with stronger throttle response and lower underhood temperatures. Fine tuned for LS torque characteristics these headers help maintain consistent exhaust scavenging across the rpm range for street or trail use.
Direct Fit Design for 1988 to 1998 4WD GM Trucks
These headers are engineered with GM specific flanges and port alignment to match LS cylinder heads without any modification. The direct fit design maintains factory clearance around the steering linkage and suspension components, making the installation process straightforward. By eliminating the need for cutting or bending, installers save time and preserve the integrity of the vehicle's frame. This tailored approach ensures a precise seal against exhaust leaks and helps retain the original underbody geometry.
1-7/8" Primaries and Mid Length Geometry
With 1-7/8 inch primary tubes, these headers strike an ideal balance between torque and top-end horsepower. The carefully calculated mid length tube routing promotes consistent exhaust scavenging across the entire RPM band. This means the engine breathes more efficiently at low speeds without sacrificing high-rpm power, resulting in smoother throttle response and a broader power curve. Enthusiasts will notice quicker acceleration off the line and stronger pull at highway speeds.
Ceramic Coating for Thermal Control
The silver ceramic shell reflects radiant heat, dramatically lowering temperatures beneath the hood. By retaining heat inside the exhaust stream, the coating improves flow velocity and reduces backpressure. It also protects the steel substrate from corrosion and wear over time, extending the service life of the headers. Cooler engine bay temperatures can benefit nearby components such as intake manifolds and electrical wiring, helping maintain consistent performance.
Heavy Gauge Steel and Flange Seal Reliability
Constructed from high-quality steel, these headers resist warping and cracking under repeated heat cycles. The mandrel-bent tubes preserve smooth internal transitions for optimal gas flow, while 3/8" thick flanges provide a rigid mating surface. This robust flange design maintains a leak-free seal even under extreme exhaust pressures, ensuring long-term reliability. The combination of durable materials and precise manufacturing delivers headers that stand up to demanding street and trail use.
These headers deliver a precise fit and reliable performance for any LS swap.
