Overview

Restore the integrity of your emissions system with this premium Volvo D13 Mack MP8 Bellows by FleetPro Parts & Tires. Specifically engineered for EPA-compliant Mack MP7/MP8 and Volvo D11/D13 engines, this heavy-duty bellows assembly connects the turbocharger to the aftertreatment system. A leaking or cracked bellows can lead to lost boost pressure, soot buildup in the engine bay, and failed DPF regenerations; this high-performance, leak-proof solution is designed to keep your truck running efficiently. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for owner-operators and fleets across the Midwest and nationwide.

Advanced Emissions Control: The Volvo D13 Mack MP8 Bellows Advantage

This Volvo D13 Mack MP8 Bellows is built to professional standards, featuring a precision-engineered 4.25" inside diameter (ID) to ensure high-velocity exhaust flow. The bellows body is designed to absorb the intense thermal expansion and engine vibrations that occur during standard operation and DPF regeneration cycles. Note: With an overall length of 17.5" and a maximum outside diameter of 6.1", this unit provides a direct "drop-in" fit for your aftertreatment plumbing, ensuring a secure seal that prevents hazardous exhaust gas from entering the cab.

At FleetPro Parts & Tires, we prioritize maintenance-ready components that reduce downtime. This Volvo D13 Mack MP8 Bellows is a direct professional-grade replacement for 23789373 and 22563153. Replacing a worn bellows is critical to maintaining proper turbo back-pressure and ensuring your SCR system receives the correct exhaust temperatures for operation. Upgrade to FleetPro quality today and keep your rig on the road.
