Engine Pro Rod Bearings, P Series, TM-77, GM LS, Set of 8

P-Series rod bearings are the oldest members of the Engine Pro 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. Engine Pro 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.
