King CR 807SI

King CR 807SI is a complete connecting rod bearing set from the bi-metal SI range. The package contains 8 pairs, or 16 bearing shells, for selected Chevrolet Small Block and GM Gen III/IV LS engines using a 2.100" connecting rod journal.

Application / fitment

The CR 807SI family is catalogued for selected Chevrolet Small Block 307/350 and GM LS 4.8-6.2 L engines with the matching crank journal and connecting rod housing dimensions. Standard and undersize versions exist, so the base number without a size suffix does not confirm the size of the physical package.

• part type: connecting rod bearings
• position: V8 connecting rods, between rod housing and crankshaft journal
• selected applications: Chevrolet Small Block 307 and 350 CID
• selected applications: GM Gen III/IV LS 4.8, 5.3, 5.7, 6.0 and 6.2 L
• application condition: nominal 2.100" journal and the correct STD or undersize version

Before installation, check the complete size marking on the package, measure the crank journals and connecting rod housings, and verify oil clearance. Install the shells in clean housings with the locating tangs correctly positioned and use the tightening procedure specified for the engine.
