What is the difference between main bearings and rod bearings?

Main bearings support the crankshaft within the engine block, while connecting rod bearings attach the connecting rods to the crankshaft. Both are critical for smooth engine operation, but they handle different loads and are located in different parts of the engine.

Do these bearings come in different sizes?

This particular set, part number 5M1051A-STD, is for standard size crankshafts. If your crankshaft has been machined undersize due to wear or repair, you will need to order a different set with the appropriate undersize dimension, such as .010" or .020".

What else might I need when installing these bearings?

When installing main bearings, it's essential to have a clean work environment and follow the manufacturer's recommended installation procedures. You'll also need to check and potentially adjust oil clearances using a tool like Plastigage, and ensure you have the correct engine oil for assembly and initial startup.

About this part

Product Details

Doing an engine rebuild on your 1971-1974 Dodge Challenger with a V8 360 engine? This ACL Crankshaft Main Bearing Set is a crucial part of that job. These bearings sit between the crankshaft and the engine block, supporting the rotating crankshaft and ensuring it spins smoothly with the right amount of oil clearance. Getting this right is key to a healthy engine.

ACL has been making engine bearings for a long time, and this set is built to meet the needs of a stock or mildly modified V8 360. They're made to the correct specifications to ensure proper oil flow and support for the crankshaft. When you're putting an engine back together, using well-made bearings like these helps ensure your hard work pays off with reliable performance.
