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

If you're rebuilding the bottom end of your GMC or Chevrolet truck or passenger car with a 366, 396, 402, 427, or 454 cubic inch V8 engine, these Clevite Tri Armor main bearings are a solid option. They're designed to handle engines that see medium to high RPM ranges, making them a good choice for performance builds or heavy-duty applications.

These H-Series bearings feature a medium level of eccentricity and high crush, which helps them seat properly against the crankshaft. The hardened steel back and thin overlay provide durability, and they are made without flash plating to ensure a better, more secure fit. This attention to detail means they're well-built to handle the stresses of a performance engine.

This set fits a wide range of vehicles, including many Chevrolet models like the C10 Pickup, C10 Suburban, Camaro, and Corvette from the mid-60s through the early 80s, as well as many GMC trucks. Always check the full fitment list to confirm compatibility with your specific vehicle.
