Engine Connecting Rod Bearing Set BMW 240i 340i 440i X5 X6 B58 3.0L

This connecting rod bearing set is designed to meet the high-stress demands of the BMW B58 and S58 3.0L Turbo engines. By implementing a "one-size-fits-all" standard replacement, this kit simplifies the complex OEM color-coded bearing selection while maintaining strict oil film tolerances. These bearings are critical for the reciprocating assembly, absorbing the combustion forces transferred from the pistons to the crankshaft. Manufactured with high-strength multi-layer alloys, they provide superior fatigue resistance and protection against metal-to-metal contact. Perfect for standard engine overhauls or maintenance where rod journals are within factory specifications, ensuring smooth operation and long-term durability in high-boost environments.
