Clevite 77 TriMetal Rod bearings have been the industry standard since the first patent on the cast, copper, lead composition decades ago.

These points are just a few of the advantages Clevite 77 TriMetal Rod bearings:

It takes Three Layers to be Number One, and Clevite 77 TriMetal are it !

Seizure Resistance:
TriMetal bearings have significantly greater seizure resistance than bi-metal bearings, by as much as 40%.
Load Capacity:
TriMetal bearings can withstand much higher loads for longer periods of time as compared to bi-metal bearings, over 60% higher.
Embedability & Conformability:
The overlay on a TriMetal bearing offers a far more forgiving surface than bi-metal bearings. These features may not be as critical during OE assembly as they once were, but they do offer additional protection that can be extremely beneficial in an engine that is poorly maintained.
Durability:
Clevite 77’s TriMetal bearings not only exceed light vehicle OE durability requirements of 150,000 miles, they also exceed heavy vehicle OE durability requirements of 300,000 miles.
Tolerances:
Because the surface layer of a TriMetal bearing adds an additional manufacturing step, Clevite regularly hold wall sizes to within .0005” as compared to a bimetal that can be held to within .0003”. This stack up of tolerances has nothing to do with quality,  suitability, or service life.
Wear Resistance:
While the silicon in the bi-metal material does contribute to slightly improved wear resistance as compared to the Babbitt surface layer of a TriMetal material, it’s at the direct expense of embedability and conformability.
