Product Details

The Sealed Power 4-2500RAA 20X2 is an A-Series bi-metal aluminum engine connecting rod bearing set designed for use in engines with a 0.020-inch oversized rod bore. Engineered as a direct-fit replacement for engine rebuilds requiring slightly enlarged bore dimensions, this set delivers precise fitment and long-term reliability.

Sealed Power's A-Series bearings feature a bi-metal aluminum alloy construction with added silicon, which provides greater surface hardness compared to conventional tri-metal bearings. The silicon particles help polish the crankshaft journal during operation, reducing wear and extending engine life. This design also offers superior seizure resistance, making it an excellent choice for stock rebuilds and mild performance applications.

Key Features:

  • A-Series bi-metal aluminum alloy construction
  • Silicon-enhanced alloy for greater surface hardness and wear resistance
  • Designed for use in 0.020-inch oversized rod bores
  • Housing bore max: 2.1252 inches (53.98 mm)
  • Greater seizure resistance than traditional tri-metal bearing designs
  • Silicon particles help polish the crankshaft journal to further reduce wear during operation
  • Manufactured under ISO and QS certified processes

Sealed Power is a trusted name in engine rebuilding, producing application-engineered replacement components backed by rigorous quality standards. The 4-2500RAA 20X2 rod bearing set is an ideal solution for engine rebuilders working with engines that require the 20X2 oversized specification.
