Walker Exhaust 42940 Heavy Duty 5" OD Aluminized Steel 90-Degree Exhaust Elbow

The Walker Exhaust 42940 is a heavy duty, 90-degree mandrel-bent exhaust elbow designed for commercial vehicle and heavy-duty truck exhaust system repair and fabrication. Featuring a 5-inch outside diameter (OD) inlet and 5-inch outside diameter (OD) outlet, this elbow delivers smooth, unrestricted exhaust flow while maintaining OE-style routing.

Constructed from durable aluminized steel, the Walker 42940 resists corrosion and withstands the extreme heat and vibration demands of heavy-duty applications. The mandrel-bent construction ensures the tube maintains its full circular cross-section throughout the bend, eliminating flow restrictions that can reduce exhaust efficiency.
