Headers - 67-82 BBM 4wd Truck

The Headers - 67-82 BBM 4WD Truck are designed to enhance the performance of classic big-block Mopar engines in full-size four-wheel-drive vehicles. These headers are ideal for automotive enthusiasts and mechanics seeking to improve exhaust flow and engine efficiency. They serve as a crucial upgrade for those restoring vintage trucks or building performance-oriented vehicles.

Constructed with a tuned primary tube design, these headers replace restrictive factory manifolds to reduce backpressure and enhance volumetric efficiency. The mandrel-bent design ensures a consistent cross-section throughout each turn, minimizing turbulence and flow restrictions that are common with cast iron manifolds. This construction technique is essential for maximizing exhaust scavenging and overall engine performance.

These headers are specifically engineered for 1967–1982 big-block Mopar four-wheel-drive trucks, making them a perfect fit for restorers and hot rodders working on models like the Dodge Power Wagon and Ramcharger. Installation is straightforward for those with mechanical skills, although it's advisable to check ground clearance on lifted vehicles. With these headers, you can expect improved throttle response and drivability across the RPM range.
