This Clevite P-Series connecting rod bearing is a 0.25 mm undersize bearing for the Mopar Gen III Hemi V8. P-Series bearings use a tri-metal design with higher load capacity than bi-metal bearings. As the most versatile Clevite replacement, they suit most OE applications and rebuilds where more demanding use is expected, such as heavy duty, motorsports or street performance. It is sold individually.
