Product Details

The Sealed Power 4056M20 is an oversize engine crankshaft main bearing set engineered for classic and vintage engine rebuilds. Part of Sealed Power's Vintage line, this bearing set is designed to restore older engines to like-new performance, offering coverage for applications over 35 years old.

Constructed with a steel-backed bronze alloy lining with overplate, these bearings deliver the conformability and fatigue resistance demanded by aged engine journals. Manufacturing is held to ISO and QS certified standards, ensuring consistent quality and dimensional accuracy across every set.

Key Features:

  • Steel-backed bronze alloy lining with overplate for superior conformability
  • Exacting tolerances for proper oil film and clearance control
  • Meets or exceeds OEM specifications
  • Engineered for fatigue resistance and long-term strength in older engine applications
  • ISO and QS certified state-of-the-art manufacturing
  • Part of Sealed Power's Vintage series — ideal for classic engine restorations
  • 0.020" (20 thousandths) oversize for use with reground crankshafts

The 4056M20 suffix indicates a 0.020" undersize grind, making this set the correct choice when crankshaft main journals have been machined 20 thousandths under standard diameter. Sealed Power is a Federal-Mogul brand with decades of trusted engine component manufacturing behind it.
