- Designed to protect the top outlet of straight-cut exhaust stacks on heavy-duty trucks, agricultural machinery, generators, and industrial equipment. Its counterweighted baffle responds to exhaust pressure, opening while driving and closing automatically when the engine is turned off, blocking the entry of rain, snow, dust, and debris that can damage the turbocharger and cylinders.
- Always compare with your OEM part number prior to purchase to confirm full compatibility.
