Standard dimension tri-metal conrod bearing shells for BMWM20/M50/M52/M54 engines

Standard dimension conrod bearing shells for the following engines:
- M20 B20, B25 and B27
- M50 B20, B25 and B27
- M52 B20, B25 and B28
- M54 B25 (2.0, 2.5, 2.7 and 2.8)
- M54 B22
- M54 B30 Designed to withstand high temperatures and stress levels, these high-resistance bearing shells are made from 3 thicknesses of tempered steel,copper and nickel.
This so-called "tri-metal" composition clearly reduces friction, thus reducing running temperatures whilst assuring greater lubrication than before.
