What does the '+0.5' size mean for these main bearings?

The '+0.5' indicates that these bearings are 0.5mm larger in diameter than standard size. This means they are intended for use when the engine's crankshaft journals have been machined down by 0.5mm to ensure proper oil clearance.

What type of engine is this bearing set best suited for?

This bearing set uses a bi-metal aluminum material and a lead-free composite, making it ideal for engines that operate under low to medium load conditions. It's a good choice for many common Nissan 2.4L applications.

Does this bearing set come with everything needed for installation?

This listing is for the main bearing set only. It does not include installation hardware or engine assembly lubricant. Always refer to your vehicle's service manual for proper installation procedures and recommended materials.
