Product Details

The Sealed Power 6-4990A is an A-Series bi-metal aluminum alloy connecting rod bearing set in a +0.25mm oversize specification, engineered for GM 3.5L and 3.9L V6 engines. Manufactured to OE tolerances under ISO and QS certified processes, this set is built for professional engine rebuilds requiring precise oversize fitment after crankshaft journal reconditioning.

Key Features:

  • A-Series bi-metal aluminum alloy construction — provides greater seizure resistance compared to conventional tri-metal bearings
  • Silicon-enhanced bearing surface — silicon particles in the alloy help polish the crankshaft journal during initial operation, reducing long-term wear
  • High-strength 1010 steel backing — delivers improved wall variance control and a stable, durable foundation for the bearing surface
  • Minimizes debris embedding — alloy composition resists particle embedment that can score crankshaft journal surfaces
  • +0.25mm oversize — designed for use with journals reground to 0.25mm undersize
  • ISO & QS certified manufacturing — consistent quality control meeting rigorous industry standards
  • Engineered as a direct OE replacement for stock rebuilds and mild performance applications

Sealed Power is a trusted name in engine rebuilding components, offering a complete line of application-engineered parts including bearings, pistons, rings, and valvetrain products. The 6-4990A bearing set delivers the precision fitment and long-term reliability demanded by professional engine rebuilders.
