Dirt Late Model Headers Crate Motor 1-3/4 1-7/9

The Dirt Late Model Headers Crate Motor 1-3/4 1-7/8 by Schoenfeld is purpose-built for competitive dirt late model racers who demand maximum exhaust scavenging and power extraction from crate motor platforms. These headers are engineered specifically for the constraints and requirements of dirt track racing, where engine bay real estate is limited and exhaust gas velocity directly translates to horsepower gains.

These Schoenfeld headers feature 1-3/4 inch primary tube diameters with a 1-7/8 inch stepped design, a configuration optimized for mid-range torque delivery and peak power in the RPM band where dirt late models operate most aggressively. The primary tube sizing and collector design work in concert to minimize turbulence and promote scavenging—pulling exhaust gases more efficiently from the cylinder heads than stock manifolds. Schoenfeld's reputation in circle track racing stems from decades of development; their headers are manufactured from mandrel-bent tubing to maintain consistent wall thickness and flow characteristics, critical factors that competitors can feel immediately in throttle response and acceleration off corners.

Crate motor builders and dirt track engine builders specify Schoenfeld headers when assembling complete power plants for late model competition. These headers integrate seamlessly into various crate motor setups, ensuring that racers can achieve optimal performance on the track. With Schoenfeld headers, drivers can expect measurable performance improvements, making them a vital component for any serious dirt late model racer.
