Perfect Circle MS1039V V-Series Main Bearing Set Standard Size

The Perfect Circle MS1039V is a high-performance V-Series main bearing set designed for Ford big block engines including 370, 429, and 460 cubic inch applications. This standard size bearing set is engineered to deliver exceptional durability and reliability for both performance builds and engine rebuilds.

Key Features:

• V-Series tri-metal construction with lead-indium overlay for superior conformability
• Unplated hardened steel backing for improved dimensional accuracy and better bore contact
• Low to medium eccentricity design for optimal crankshaft support
• Single-piece thrust bearing design eliminates need for assembled thrust bearings
• Standard size (.000) for use with stock crankshaft journals

The V-Series bearings feature a lead-indium surface alloy that provides better conformability compared to traditional lead-tin-copper overlays, making them ideal for high-performance applications where precise fitment and reduced friction are critical. These bearings are compatible with Ford 429 and 460 engines from 1968-1998 applications.
