Product Details

The King Engine Bearings MB5520AM is an AM-Series OE-Replacement Main Bearing Set designed for Opel C20XE, X18XE, and X22XE engines. This set delivers reliable, factory-quality crankshaft support using King's proven bi-metal aluminum construction, making it an excellent choice for engine rebuilds and maintenance on these Opel four-cylinder platforms.

Key Features:

  • Bi-Metal Aluminum Construction: Standard aluminum-based material equivalent to SAE-783 — the softest bi-metal in King's range, engineered for low to medium load passenger car engines
  • OE Replacement Grade: Designed to meet or exceed original equipment specifications for a direct-fit replacement
  • Lead-Free Material: Environmentally conscious, lead-free composite bearing material that is safer to handle and install
  • Superior Embeddability: Allows micro-particles to embed safely into the bearing surface, reducing the risk of crank journal scratching and overlay damage
  • Precision Tolerance Control: Manufactured to tight tolerances of ±0.0001 inch for consistent clearance and reliable oil film maintenance
  • Single Oil Hole: Optimized oil feed geometry for proper lubrication of the crankshaft journals
  • Complete Set: Includes 5 pairs (upper and lower shells) to cover all main journals

King Engine Bearings has specialized exclusively in engine bearings since 1960, with every bearing produced under one roof and subject to rigorous multi-stage quality control. The MB5520AM is the standard-size variant; an oversize version (MB5520AM1.5) is also available for reground crankshafts. Cross-reference OEM numbers include 90 169 662, 90 169 656, and 90 169 655, as well as AE reference AEM5401.
