Spherical M13-1011 Exhaust Bushing

The genuine OEM spherical exhaust bushing M13-1011 is designed to provide a durable, vibration-isolating connection in heavy-duty truck exhaust systems — particularly for Kenworth and Peterbilt applications. This critical component helps maintain correct alignment of the exhaust stack, reduces metal-to-metal contact, and dampens the vibration and movement of the exhaust system under load.
