King Coated Undersized Crank Main Bearing Set -.001 Subaru WRX 02-14 / STI 04-21 | MB5382XPGC.026

The King Engine Bearings pMaxKote Performance Main Bearing Set in Size .026 is a top - notch choice for Subaru EJ20, EJ22, and EJ25 engines (including turbo), with thrust in the #5 position. It fits multiple Subaru models such as the 2002 - 2014 WRX, 2004 - 2021 STI, 2005 - 2009 Outback XT, 2005 - 2009 Legacy GT, and 2005 - 2006 Baja Turbo. King's pMaxKote is a game - changing approach to coated bearings. A unique polymer coating is added over the pMaxBlack overlay during manufacturing. The ceramic nano - composite particles in pMaxKote act as a fourth layer, enhancing wear resistance and protecting against oil starvation without altering the bearing's original precision wall thickness. This bearing set offers many features, like being an undersized -.001 in at the crankshaft main bearing location. It has a unique metal structure for high load capacity, a distinctive geometric design, and is designed with a performance simulation and analysis system. Other features include a 4.5% Tin intermediate layer, 5% copper overlay, a micro - etch surface preparation process, and a proprietary nano - scaled hardening process. Each set has perfect clearance, and the U - groove design increases the bearing's effective surface. The integrated oil slot ensures better oil passage and improved oil ingress.

Using this King main bearing set is straightforward. First, make sure your Subaru engine (EJ20, EJ22, or EJ25) is suitable as per the fitment information. When installing, handle the bearings gently to avoid any damage. Check that the thrust is in the #5 position as required. During use, keep an eye on the oil level regularly to prevent oil starvation, as the pMaxKote coating offers protection but it's still important to maintain proper lubrication. For maintenance, follow the normal engine maintenance schedule. Periodically inspect the bearings for any signs of wear. If you notice any abnormal noise or performance issues from the engine, it might be a good idea to check the bearings. This will help ensure the long - lasting performance of your engine and the bearings.
