Product Details

The King Engine Bearings MB3346AM0.25 is a main bearing set engineered for Subaru 1800cc engines produced from 1980 onward. This set provides a reliable, precision-fit solution for engine rebuilds and overhauls requiring a 0.25mm oversized bearing to accommodate reground or worn crankshafts.

Material Construction:

  • Bi-Metal Aluminum (AM Series) — Standard aluminum-based bearing material equivalent to SAE-783
  • Designed for low to medium load engine applications
  • Aluminum alloy overlay provides excellent conformability and embeddability
  • Corrosion-resistant properties suitable for modern engine oils and extended service intervals

Key Features:

  • 0.25mm oversized bore for use with reground crankshafts
  • Precision-engineered to King's exacting tolerances for proper oil film and clearance
  • Steel-backed bi-metal construction for durability and strength
  • Direct replacement for OEM main bearings on compatible Subaru 1800cc applications

King Engine Bearings is a globally recognized manufacturer of high-quality engine bearings, trusted by professional engine builders and OEM suppliers worldwide. The AM series is an ideal choice for stock rebuilds and moderate-performance applications where reliable, long-lasting bearing performance is required.

Good so far, but all that I've done is place the order and pay for the equipment.

Seemed fine.

Autoplicity was easy to deal with, and the price was hard to beat. Will use again.

I don't typically review online stores, but Autoplicity was awesome! Shipped ridiculously quickly and my H&R springs were at my house two days after I ordered. Awesome, and for a great price. Thanks guys
