Clevite rod bearings come in a wide assortment of styles for a huge range of vehicles, from mild to wild.
They are made to meet or exceed OEM standards for strength and durability, and will help give your engine extra life.
Their quality construction and superior materials protect vital parts from the harmful effects of friction.
Plus, there are thousands of applications, with subtle differences that cover numerous variations and usages.
So you are sure to find the bearings you need for your engine.
P-Series Bearings These are not to be confused with the standard passenger car and light truck parts for the same retention applications which also have a P suffix letter.
These high performance parts have unique core part numbers different from the standard parts for the same application.
P-Series parts are the oldest series of Clevite high performance bearings.
The rod bearings in this series typically have the greatest amount of eccentricity.
Most rod bearings are available either with or without dowel holes for use in aluminum rods.
Most P-Series main sets are full grooved to maximize oil flow to the rod bearings.
Both rods and mains have high crush for maximum retention, and a reduced overlay thickness to prevent overlay fatigue, sometimes referred to as hen tracking.
Rod bearings use a hardened steel back for added strength and resistance to fretting.
Extra clearance rod bearings are available for .001 additional clearance and select fitting.
Use the P-Series rods where extremely high RPMs cause severe rod bore close-in.
This is typically indicated by nearly full parting line to parting line shaft contact with bearings having less eccentricity.
Use P-Series mains where higher eccentricity is desired to narrow bearing contact patterns and to provide increased oiling to rod bearings.
Rod bearing oil starvation is typically indicated by polishing and smearing of the bearing surface, possibly accompanied by discoloration predominantly concentrated at the axial.
