Engine Connecting Rod Bearing Pair

Product Overview

Ideal for rebuilding engines where more demanding use is anticipated, such as heavy duty, motorsports, or street performance. As it is the most versatile replacement, Clevite® engine bearing P-Series is suitable for most OE applications. Due to the increased load capacity of the TriMetal design, it is a suitable upgrade from BiMetal engine bearings.

Unless otherwise specified, some brands supply brake rotors, pistons, strut mounts, rods and rings separately.

P-Series rod bearings are the oldest members of the Clevite 77 performance bearing family. They're intended for high-revving engines, especially those where the high rpm cause the rod bores to narrow. To compensate for this distortion, these direct replacements have higher eccentricity and a high crush factor. Clevite P-Series rod bearings are built on hardened-steel backings with extra-thin overlays, and their lower sections have dowel holes for use with aluminum rods, and there are extra-clearance variations available with an additional 0.001 in. of clearance. Order the model designed for your vehicle and engine application.
