ITM Engine Crankshaft Main Bearing

ITM Engine Crankshaft Main Bearings: Import-Focused Precision for Every Rebuild

When an engine rebuild demands reliable, precisely dimensioned crankshaft main bearings, ITM Engine Components stands out as one of the aftermarket's most trusted names. ITM is a wholesale distributor and importer of internal engine components for passenger vehicles and light trucks, with over forty years of experience in the automotive aftermarket — with coverage that is predominantly import, including Asian and European vehicles. That deep import focus translates directly into one of the most comprehensive engine crankshaft main bearing catalogs available anywhere in the aftermarket.

Broad Coverage Across Import and Domestic Platforms

ITM's main bearing lineup is built around the vehicles that professional rebuilders work on every day. Sets are available for a wide range of applications, from classic Honda Civics and Accords spanning the 1970s through the 1990s, to Toyota Tacoma, 4Runner, T100, and Previa engines, as well as Nissan pickups and sedans from earlier decades. ITM also carries domestic applications based on import platforms and some pure domestic applications based on specific product groups, making their catalog useful well beyond strictly foreign-nameplate garages.

Each main bearing set is offered in standard sizing as well as common undersizes — typically .010, .020, and .030 of an inch — to accommodate crankshafts that have been turned during the reconditioning process. This range of oversize options is critical for any serious engine rebuild shop that services both freshly worn and previously machined crankshafts.

OE-Equivalent Quality Through Strategic Sourcing

What distinguishes ITM in the aftermarket is their strategic sourcing approach — many ITM parts come from the same companies that supply them to the factories of leading car manufacturers, which allows the brand to offer genuine OE-equivalent quality without the premium pricing. For crankshaft main bearings — components that must maintain precise oil film clearances under extreme rotational loads and temperatures — that level of dimensional accuracy is not a luxury, it's a necessity.

Because ITM is one of the first importers in this space, they have many longstanding relationships with manufacturers from around the world, and communication between those manufacturers and ITM is a very thorough process ensuring that customers receive the best possible components at competitive pricing.

A Catalog Built for Rebuilders

ITM currently has inventory for 12,000+ part numbers, 45 different product lines, and applications for approximately 500+ engines. With 384 crankshaft main bearing sets in this catalog alone, the depth of coverage for this single critical component category reflects how seriously ITM takes the engine rebuild market. Although ITM's components are primarily for passenger vehicles and light trucks, some engines do carry over into the industrial market, giving fleet and equipment technicians additional options as well.

Whether you are performing a complete bottom-end rebuild on a Japanese import, refreshing a European four-cylinder, or overhauling a domestic engine built on a shared platform, ITM's crankshaft main bearing sets deliver the fitment and material quality that the job demands.
