ACL Nissan VG30DETT 3.0L-V6 0.50 Oversized High Performance Main Bearing Set

When you're rebuilding a Nissan VG30DETT engine, especially one that's seen some miles or is being prepped for performance, getting the main bearings right is crucial. This set from ACL is specifically made to be 0.020 inches larger than stock (that's what the '.50' means in the part number) to help you out. This size is often needed when the original crankshaft journals have been machined down due to wear or to prepare for a performance build.

ACL has been around for a long time, and they make well-built engine components. These main bearings are designed for high-performance applications, meaning they can handle more stress than standard bearings. They're made with materials and tolerances that help maintain oil pressure and reduce friction, which is key for engine longevity and power, especially in boosted VG30DETT engines. Installing these bearings is part of a larger engine rebuild process, so make sure you have the service manual for your specific vehicle to follow the correct procedures for cleaning, oiling, and torquing the main caps.

This set covers the main bearings for your VG30DETT. Remember to check the crankshaft for straightness and proper journal sizing before installation. If you're unsure about any part of the engine rebuild process, it's always best to consult a professional mechanic.
