King Engine Bearings CR 868SI1.0 Connecting Rod Bearing Set Si-Series +1.0mm Oversize

The King Engine Bearings CR 868SI1.0 is a complete connecting rod bearing set from King's SI-Series, engineered for Ford V8 SOHC engines. This set is sized at +1.0mm oversize, making it the correct choice for engine rebuilds where the crankshaft rod journals have been machined 1.0mm undersize.

SI-Series Material — Bi-Metal Silicon Aluminum:

• Bi-metal construction with an aluminum-silicon base alloy (Al12Sn2.5Si1Cu)
• Aluminum base material strengthened with 2.5–3% silicon for improved fatigue strength and hardness
• Designed for medium-load engines and engines with nodular cast iron crankshafts
• Lead-free OE-replacement formulation — a modern, environmentally conscious alternative to traditional tri-metal bearings
• No overlay — the SI alloy surface serves as the bearing face directly

King Bull's Eye Tolerance™ Technology:

• Proprietary production process combining highly accurate CNC machining with computerized wall thickness monitoring
• Real-time in-process adjustments ensure each bearing half meets extremely tight dimensional tolerances
• Consistent wall thickness across the entire set for uniform oil clearance

Set Contents:

• 8 pairs (16 individual bearing shells) — upper and lower halves for all connecting rod journals
