King offers rod bearings in 3 levels for use in OE Stock, High Performance, and Extreme Performance applications.
Connecting rod bearings from King are sold in engine sets.
CP-Series, AM-Series & SI-Series bearings are recommended for OE applications.
CP-Series bearings are copper-lead on steel (Tri-Metal) with a .001" copper-lead tin overlay.
AM-Series bearings are aluminum-copper-tin plus Alloy on high-strength steel (Bi-Metal).
SI-Series bearings are Silicon-Aluminum bearings (Bi-Metal) designed for Aftermarket Gasoline or Diesel Engine Rebuilding & Performance Engines with OE Crankshafts.
HP-Series bearings are recommended for street and strip high performance applications.
These Bi-Metal Silicon Aluminum bearings are designed for blown, turbocharged, NOS, and alcohol-fueled engines using aftermarket crankshafts.
These bearings have chamfered oil holes to fit aftermarket cranks machined with a large radius at the edge of the journals.
They are ideal for use in High Load, Short Duration Applications like Drag Racing, Tractor Pulling, and Monster Trucks.
XP-Series bearings are for extreme performance in high-load capacity applications.
These Tri-Metal copper lead bearings are designed for use on cranks with large radii (narrow rod bearings) and feature enlarged, chamfered oil holes.
They are ideal for use in High Load Circle Track & Endurance Applications.
The King part number Prefix/Suffix indicates specific characteristics.
Note that the term "Undersize" refers to a thicker bearing used when the Crankshaft has been turned down and is now undersized, not the bearing itself.
The term "Oversize" typically refers to a thinner bearing than stock to allow for increased clearance.
