Take your Jeep CJ to the next level with these Hedman Hedders engineered for AMC V8 engines. Designed for inside-chassis fitment, these headers provide the clearance and performance necessary for off-road enthusiasts and street drivers alike. By replacing restrictive factory manifolds, you will notice a significant improvement in mid-range torque and overall engine efficiency.

Key Features and Benefits

  • Primary Tube Diameter: 1.625 inches
  • Collector Diameter: 3 inches
  • Finish: High-temp black paint

These headers are specifically tuned to help your AMC V8 breathe, allowing for better exhaust gas evacuation. The 1.625-inch primaries are optimized to maintain exhaust velocity, which is crucial for the low-end grunt required for trail climbing and heavy-duty use. The 3-inch collectors provide ample flow for high-performance exhaust setups. Built to withstand the rigors of off-roading, these headers feature thick flanges to prevent leaks and ensure a secure seal against the cylinder head.
