Clevite Tri Armor GMC Pass & Trk 366/396/402/427/454 Main Bearing Set

If you're rebuilding the bottom end of your classic GMC or Chevrolet V8, like those found in a 1970 Chevelle or a 1980 C10 pickup, a solid set of main bearings is crucial for engine longevity. This Clevite Tri Armor Main Bearing Set, part number MS829P, is designed to handle the demands of these larger displacement engines, including the 366, 396, 402, 427, and 454 cubic inch displacements.

These bearings feature Clevite's Tri Armor coating, a specialized surface treatment that helps to reduce friction and improve wear resistance. This means better protection for your crankshaft journals, especially during the critical break-in period and under normal operating conditions. The well-built construction ensures they fit right into your engine block, providing the support your crankshaft needs to spin smoothly.

This set is a popular choice for engine rebuilds across a wide range of Chevrolet and GMC trucks and passenger cars from the 1960s through the late 1990s. Make sure to follow the manufacturer's installation instructions carefully for proper seating and break-in.
