King rod bearings for BMW S65B40 and S65B44 engines

SV/GPC – New Material for Extreme Loads

King’s new silver based SV and GPC tri-metal material handles 17,000 PSI compared to available race materials that peak at 11,000 PSI. SV and its polymer coated version, GPC, feature an intermediate lead-bronze layer over steel, topped by a silver overlay containing solid lubricant particles. GPC’s polymer coating helps protect the bearings in case of oil starvation and metal-to-metal contact. 

GPC Attributes

Modified engines can suffer from issues such as low oil pressure and oil starvation, which can cause premature rod and/or main bearing failure. Additionally, the greater loads and increased cylinder pressures can easily fatigue “street duty” engine bearings, again leading to premature failure.
