King Engine Bearings Nissan VK45DD/E/ VK50VE/ Vk56DE/VD (Size 0.25) Main Bearing Set

When you're rebuilding the heart of your engine, especially for a Nissan VK45DD/E, VK50VE, or VK56DE/VD engine found in many Infiniti and Nissan vehicles, the main bearings are critical. These bearings sit between the crankshaft and the engine block, supporting the crankshaft's rotation and handling significant loads. King Engine Bearings specializes in these vital components, and their MB5770XP0.25 set is designed to meet the demands of these powerful V8 engines.

This set features King's PMaxBlack overlay, which is a tri-metal copper-based material that offers superior load capacity compared to standard bearings. This means they can handle more stress without failing, which is important for engines like the VK56DE. They also incorporate Radialock technology, which helps maintain optimal crush height during installation, ensuring the bearing stays securely in place for consistent performance. This attention to detail in material and design contributes to a well-built component that supports the longevity of your engine rebuild.

This main bearing set is a 0.25mm undersize set, meaning it's intended for crankshafts that have been machined down by that amount. It's a solid option for many Infiniti FX45, M45, QX56, Nissan Armada, and Titan models from the mid-2000s through the early 2020s. Always ensure you confirm fitment for your specific vehicle and that your crankshaft has been properly machined to the correct undersize before installation.
