What is the main function of main bearings in an engine?

Main bearings support the crankshaft within the engine block. They reduce friction between the rotating crankshaft and the stationary engine block, allowing for smooth operation and preventing excessive wear.

Why are these considered 'Race Series' bearings?

The Race Series designation indicates these bearings are built with enhanced materials and construction to withstand higher loads and temperatures typical of performance or racing applications. They offer improved fatigue strength and wear resistance compared to standard bearings.

Do I need any special tools or supplies for installation?

While installation requires standard engine rebuilding procedures, it's highly recommended to use a quality engine assembly lube to protect the bearing surfaces during initial startup. Ensure your crankshaft journals are clean and within factory specifications.

About this part

Product Details

ACL has been making engine bearings for decades, and this Race Series Main Bearing Set for your 2015-2018 Dodge Challenger is one of their staples. These bearings are crucial for keeping your 6.2L V8 engine running smoothly by supporting the crankshaft and reducing friction. If you're rebuilding or refreshing your engine, especially if you plan on pushing it hard, a solid set of main bearings is a must-have.

This set is built with ACL's Race Series in mind, meaning they're made to handle the extra stress that comes with higher performance applications. They use a specialized overlay material that's designed for improved fatigue strength and wear resistance, which is important when you're dealing with the increased loads and heat of a performance engine. The standard size ensures a direct fit for engines that haven't been machined undersize or oversize, making installation straightforward as long as the crankshaft journals are in good condition.

When you're installing main bearings, it's always a good idea to have a quality engine assembly lube on hand. This helps protect the bearing surfaces during initial startup before your engine's oil pressure fully builds. Make sure to also check your crankshaft journals for any imperfections or wear that might affect bearing performance.
