King Engine Bearings CR6869SI010 SI-Series Connecting Rod Bearing Set Undersize - 010

The King Engine Bearings CR6869SI010 is a 0.010-inch undersize connecting rod bearing set engineered for Jeep 232ci, 242ci, and 248ci engines, as well as the Rambler 232ci inline-six. Part of King's SI-Series line, these bearings are purpose-built for OE replacement and aftermarket engine rebuilding applications.

Constructed using King's bi-metal Silicon Aluminum (SI) material, the bearing shell features an aluminum-based alloy lining reinforced with 2.5–3% silicon, bonded to a precision steel backing. This construction is specifically suited for medium-load engines and nodular cast iron crankshafts, delivering excellent conformability, embedability, and wear resistance.

Key Features:

• SI-Series bi-metal construction — silicon-aluminum alloy lining on steel backing for reliable OE-grade performance
• 0.010-inch crankshaft undersize — designed for use with journals ground 0.010" under standard diameter
• Improved surface finish — reduces microscopic ferrite peaks on improperly ground or polished nodular cast iron crankshafts
• Optimized oil clearance — helps reduce wear, lower operating noise and vibration, and minimize excess oil flow
• Bull's Eye wall tolerance — bearing wall thickness held to ±0.0001" for precise, consistent oil clearances shell to shell
• Designed for aftermarket gasoline engine rebuilding with OE-type crankshafts

King Engine Bearings has specialized exclusively in engine bearings since 1960, applying lessons from motorsport engineering to every OE-replacement product in their lineup. The CR6869SI010 delivers the precision fitment and material quality expected from a dedicated bearing manufacturer.
