ACL Chevy V8 LT1/LT4/L86 Race Series Standard Size High Performance Main Bearing Set

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 Race Series set from ACL is built for high-performance applications, offering a step up from stock hardware. They're designed to handle the demands of engines like the 6.2L found in many Camaros and Corvettes.

What sets this ACL set apart is the inclusion of an extra lower thrust shell. This gives you flexibility during installation: you can run a full 360-degree thrust setup for maximum support, or opt for a 180-degree setup by using the upper thrust shell with a plain lower shell, discarding the extra parts. This allows you to tailor the bearing setup to your specific engine build and performance goals.

This is a standard size set, meaning it's intended for crankshafts that are still within factory specifications. If your crankshaft has been machined, you'll need an undersize bearing set. Always refer to your engine's service manual for proper installation procedures and specifications.
