Ideal for rebuilding engines where more demanding use is anticipated, such as heavy duty, motorsports, or street performance. As it is the most versatile replacement engine bearing, P-Series is suitable for most OE applications. Due to the increased load capacity of the TriMetal design, it is a suitable upgrade from Bimetal engine bearings.

Features

  • Manufactured from cast copper-lead, increases fatigue strength by approximately 20% compared to powdered metal processes, referred to as sintering, which is used by the competition
  • Provides a margin of forgiveness for vehicles that don't get maintenance service as often as they should
  • Additional embed ability makes it a good choice for older engines
  • Manufactured to meet or exceed OE specifications

Clevite MS-1432P-10 Engine Crankshaft Main Bearing Set

Model: MS-1432P-10   |    Mpn: MS-1432P-10   |    Ean: 0027067552723   |    PartNumber: MS-1432P-10   |   Asin: B000COMY4O

Ideal for rebuilding engines where more demanding use is anticipated, such as heavy duty, motorsports, or street performance. As it is the most versatile replacement engine bearing, P-Series is suitable for most OE applications. Due to the increased load capacity of the TriMetal design, it is a suitable upgrade from Bimetal engine bearings.

Features

  • Manufactured from cast copper-lead, increases fatigue strength by approximately 20% compared to powdered metal processes, referred to as sintering, which is used by the competition
  • Provides a margin of forgiveness for vehicles that don't get maintenance service as often as they should
  • Additional embed ability makes it a good choice for older engines
  • Manufactured to meet or exceed OE specifications

Clevite MS-2207A-.50MM Engine Crankshaft Main Bearing Set

Model: MS-2207A-.50MM   |    Mpn: MS-2207A-.50MM   |    Ean: 0027067647962   |    PartNumber: MS-2207A-.50MM   |   Asin: B004A28RVS

Carrying on a tradition of durability and dependability, Clevite Bimetal (aluminum) engine bearings feature 100% lead-free aluminum silicon. Engineered with 60% more silicon than comparable competitive replacements, they provide better conditioning of journal surfaces. This results in greater seizure and wear resistance.

Features

  • Manufactured from cast copper-lead, increases fatigue strength by approximately 20% compared to powdered metal processes, referred to as sintering, which is used by the competition
  • Relatively harder aluminum alloy wears well, interacts closely with journal surfaces for strength
  • Recommended for use with nodular iron crankshafts
  • Manufactured with 100% bored inside diameters for optimum surface characteristics and consistent precision
  • Manufactured to meet or exceed OE specifications
