King Engine Bearings XP Main Bearing Set - Nissan VK45/VK50/VK56 2002-2024 (STD)

The King XP Series is a copper based tri-metal race main bearing set finished with King's pMaxBlack overlay, a hardened surface layer King rates at 10,200 psi against roughly 8,000 to 8,500 psi for a conventional overlay. That extra fatigue strength is what lets a bottom end take boost or sustained high rpm without the mains giving up first. SecureBond micro-etch bonding anchors the overlay to the intermediate layer. The set covers all five main journals, ten shells in total, in standard size for a crankshaft that has not been reground.
