Technical Guidance
Bearings, crankshafts, gaskets, and EGR systems play essential roles in maintaining pressure, reducing friction, and supporting emission control. A failed bearing or gasket can lead to downtime, while precision-fitted pumps and sensors restore efficiency in cooling and lubrication systems. For scheduled service, choose truck repair parts that match the exact OEM number, and consider complete replacement engine parts sets to streamline overhauls.FAQs
