King Engine Bearings CR6887SV0.75 Performance Connecting Rod Bearing Set Oversize - 0.75mm

The King Engine Bearings CR6887SV0.75 is a complete connecting rod bearing set engineered for the BMW B58B30A 3.0L inline-six engine. This is an oversize +0.75mm set, designed for use during engine rebuilds where the connecting rod journals have been machined or where additional oil clearance is required beyond standard sizing.

These bearings feature King's premium SV silver-based tri-metal construction — a lead-free material consisting of a steel backing, an intermediate lead-bronze layer, and a silver overlay containing solid lubricant additives. This advanced architecture is rated to handle up to 17,000 PSI of load, far exceeding conventional race bearing materials that typically peak at 11,000 PSI.

Key Features:

• SV Silver Tri-Metal Material: Lead-free, silver-based overlay with solid lubricant particles distributed throughout the silver matrix for extreme load capacity
• +0.75mm Oversize: Engineered for use with crankshafts machined 0.75mm undersize on the rod journals
• High Load Rating: Capable of withstanding up to 17,000 PSI — ideal for performance and modified B58B30A builds
• Lead-Free Construction: Environmentally responsible materials without sacrifice to strength or durability
• Precision Tolerances: Manufactured to exact OEM-spec wall thickness tolerances for optimal oil clearance and fitment
• Full Set: Includes all required bearing shells for all connecting rods in the engine

The B58B30A engine, found in a wide range of BMW 3 Series, 4 Series, 5 Series, 7 Series, X3, X4, X5, X6, X7 models, and the Toyota GR Supra (A90), is a popular target for performance modifications. Highly modified B58 engines are particularly susceptible to premature rod bearing failure due to elevated cylinder pressures and increased loads — making a purpose-built performance bearing like the CR6887SV0.75 the correct choice for any serious engine rebuild.
