Set of standard dimension crankshaft bearings,

For E30 from 03/88->
- 320 i M20
- 325 i/ix M20
- 325 e M20 Designed to withstand high temperatures and greater stress, these highly resistant bearings consist of three layers of tempered steel, copper and nickel.
This 'tri-metal' composition clearly reduces friction, thus reducing running temperatures while assuring better lubrication than the original parts
