What is the advantage of the extra lower thrust shell?

The extra lower thrust shell allows you to choose between a 360-degree thrust setup for maximum support, or a 180-degree setup by using a plain shell on the lower side. This flexibility helps tailor the bearing setup to your specific engine build needs.

Why do these bearings come in an oversized size?

These bearings are .010 inch oversized. This means they are slightly larger than standard size and are intended for use when the crankshaft journals have been machined down (ground) during an engine rebuild or performance modification.

Product Details

When you're building or rebuilding a GM LT1, LT4, or L86 V8 engine, the main bearings are critical for keeping everything aligned and running smoothly. This set from ACL is specifically designed for high-performance applications and comes with a unique feature: an extra lower thrust shell. This gives you the flexibility to set up your engine with either a full 360-degree thrust bearing, which offers maximum support, or a 180-degree setup if you prefer to use a plain shell on the lower side.

These are .010 oversized bearings, meaning they are slightly larger than stock to account for crankshaft journals that have been machined down during a rebuild. The Race Series designation means they're built to handle the increased demands of performance engines. ACL is known for making well-built engine components, and this main bearing set is no exception, offering a solid option for your engine build.

This set is verified to fit the 2016-2024 Chevrolet Camaro and the 2014-2019 Chevrolet Corvette. Make sure to check your specific engine code to confirm compatibility, but these are designed for the popular LT V8 platforms.
