King Engine Bearings CR4637SV0.5 SV-Series Connecting Rod Bearing Set +0.5mm Oversize

The King Engine Bearings CR4637SV0.5 is a +0.50mm oversize connecting rod bearing set engineered for Audi engines using the BYT, CDNC, CCZD, and CPSA engine codes. Built on King's premium SV-Series tri-metal platform, these bearings deliver the material quality and dimensional precision demanded by high-performance and heavily modified engines.

SV-Series Material Technology:

• Lead-free, tri-metal construction featuring a silver-based overlay with solid lubricant additives distributed throughout the silver matrix
• Babbitt plating provides exceptional seizure resistance during cold starts and oil starvation events
• Capable of handling up to 17,000 PSI load capacity — significantly exceeding conventional aftermarket bearing materials
• Suitable as a sputter bearing replacement for OE-spec sputter-type bearings
• Copper-based intermediate lining (Cu8Sn4Bi) over steel backing for long-term durability

King Bull's Eye Tolerance™ Manufacturing:

• Combines precision CNC machining, controlled overplating, and computerized wall thickness monitoring
• Shell-to-shell thickness variation is tighter than industry standard, ensuring consistent oil clearance across all cylinders
• Every bearing passes multiple quality control checkpoints before leaving the facility

The +0.50mm oversize designation makes this set ideal for engine rebuilds where the crankshaft journals have been reground 0.50mm undersize. This set includes all required rod bearing shells to service the full engine. King Engine Bearings has been a trusted name in engine bearing manufacturing since 1960, supplying bearings to the automotive, aviation, marine, and motorsport industries worldwide.
