King Subaru EJ205/EJ255/EJ257 (Size STDX) pMaxKote Performance Rod Bearing Set | CR4125XPGCSTDX

Fitment: EJ205/EJ255/EJ257 Engines Features: Nano-composite Polymer Coating – With No Added Thickness! Anti-Friction Coating Material: pMax Black (racing line) Journal Size: 52mm No Machining Required Size: .001 Oversized pMaxKote™ enhances the following benefits of King XP race bearings: Superior seizure resistance Superior cavitation resistance Superior wear resistance Superior protection against oil starvation pMaxBlack™ tri-metal structure Intermediate layer The intermediate layer of a typical race bearing contains 2-3% tin, with hardness values of 90-95 HV. For a superior pMaxBlack™ intermediate layer, we increased the tin content to 4.5%, making it 22% harder at 115 HV, with a load carrying capacity of 17,000 psi. pMaxBlack™ Overlay The overlay of a typical high performance bearing consists of a leaded alloy that contains 2-3% copper. It achieves a hardness level of 11 – 14 HV, and a maximum load capacity of 8,000-8,500 psi. King’s pMax Black™ overlay is significantly stro
