King Engine Bearings CR803SI060 SI-Series Connecting Rod Bearing Set Chevy SBC 265 283 327 0.060" OS

The King Engine Bearings CR803SI060 is an SI-Series bimetal connecting rod bearing set designed for Chevrolet small-block (SBC) engines displacing 265ci, 283ci, and 327ci. This set is sized at 0.060" oversize, designed for use with crankshafts that have been reground 0.060" undersize. The set includes 8 pairs of rod bearing shells to complete a full engine rebuild.

King's SI-Series bearings use a bimetal aluminum-silicon base construction, making them an ideal OE-replacement choice for medium-load engines — especially those equipped with nodular cast iron crankshafts. The improved surface finish reduces microscopic ferrite peaks on improperly ground or polished crankshaft journals, helping protect bearing and journal surfaces during break-in and beyond.

Key Features:

• Bimetal aluminum-silicon (SI) construction for medium-load OE replacement applications
• 0.060" oversize — fits crankshafts reground 0.060" undersize
• Improved surface finish reduces ferrite peaks on nodular cast iron crankshafts
• Optimized oil clearance to reduce wear, operating noise, and excess oil flow
• Industry-leading wall thickness tolerance of ±0.0001" for precise, consistent fitment
• Set includes 8 pairs (16 shells) — enough for a complete V8 engine rebuild
• Compatible with Chevrolet SBC 265ci, 283ci, and 327ci engines
