What does 'full groove' mean for these bearings?

A full groove bearing has a continuous groove around the inside diameter. This helps to distribute oil more evenly to the entire surface of the crankshaft journal, which is beneficial for lubrication and reducing wear.

Are these bearings for a standard or oversized crankshaft?

This is a standard size (STD) bearing set. They are designed to fit a factory-spec crankshaft. If your crankshaft has been machined undersize or oversize, you will need a different bearing size.

What else might I need when installing these main bearings?

When installing main bearings, it's essential to use engine assembly lube to ensure proper lubrication during initial startup. You'll also need a torque wrench to tighten the main bearing caps to the manufacturer's specifications.

Product Details

Doing an engine rebuild on your 1974-1981 Plymouth Trailduster with a 360 V8? These ACL standard crankshaft main bearings are a key part of getting your engine running smoothly again. They support the crankshaft, allowing it to spin freely within the engine block while handling the loads from combustion.

This set features full groove bearings, which help distribute oil more evenly around the crankshaft journal. This is especially important for engines from 1974 onward, as specified by ACL. Using standard size bearings ensures a precise fit on your factory crankshaft, assuming it hasn't been machined undersize or oversize. ACL is a well-known name in engine bearings, and this set is a solid option for a reliable rebuild.

When you're rebuilding an engine, it's critical to have all the right components. Make sure you have the correct assembly lube and follow the manufacturer's torque specifications when installing these bearings to ensure proper function and longevity.
