EXHAUST ELBOW ALZ PETE/ ///EP50EL90124

It helps route exhaust gases from the engine to the tailpipe, maintaining proper backpressure and preventing leaks. Replacement is typically necessary when the original elbow rusts through, cracks, or becomes bent from road debris or vibration. The part is commonly used as a direct-fit replacement for certain Peterbilt and Kenworth chassis with 5-inch exhaust plumbing.
