Product Details

The Sealed Power 7245MA30 is an MA Series crankshaft main bearing set designed for Ford and Mazda V6 engines (2.9L and 4.0L). This set is sized at 0.030-inch crankshaft undersize, making it the correct choice for engines with reground or worn crankshafts that have been machined to the 0.030" undersize specification. The set includes 4 bearings and features a half-groove (1/2 groove) design.

Sealed Power's MA Series bearings use a proprietary bi-metal aluminum alloy construction — a silicon-aluminum-tin surface alloy bonded over a high-strength 1010 steel backing. The silicon content provides exceptional surface hardness and wear resistance, and is known to gently polish crankshaft journals during break-in, helping to optimize surface finish on journals that haven't been perfectly prepared.

Key Features:

  • 0.030-inch crankshaft undersize for use with reground crankshafts
  • Bi-metal aluminum alloy bearing surface over 1010 steel backing
  • Silicon additive improves wear resistance and can polish crankshaft journals
  • Half-groove (1/2 groove) design for optimized oil distribution
  • Improved seizure and corrosion resistance vs. standard materials
  • Tight wall variance control for precise oil clearance
  • Minimizes debris embedding to protect crankshaft surfaces
  • Meets or exceeds OEM specifications
  • Manufactured under ISO & QS certified processes

Sealed Power is a Federal-Mogul brand with decades of OEM and aftermarket engine bearing experience. The 7245MA30 is a direct-fit replacement engineered for reliability in both street rebuilds and performance applications.

Very quick and easy. Thanks

I ordered an AEM intake for my F-150 on Christmas day and received it on the 29th. I would absolutely recommend this site to anyone looking for car parts - they had the lowest price by far and shipped fast. Great job!

very good price fast shipping

Found Autoplicity by doing Google search looking for Corsa Sport Axle Back exhaust for my 2008 GT500. By far the best price, even cheaper than other big companies with free shipping by far. Ordered them on Thursday afternoon and got them 24 hours later in NY with the standard shipping. Could'nt be happier.

fast, polite service when we had a question
