King Engine Bearings CR4668XP STDX pMax Black Tri-Metal Racing Connecting Rod Bearing Set

The King Engine Bearings CR4668XP STDX is a high-performance tri-metal connecting rod bearing set engineered for the Hyundai G4KE and G4KC engines. Built under King's flagship XP Racing Series, these bearings are designed to meet the extreme demands of high-output, high-RPM performance and competition builds.

These bearings feature King's proprietary pMax Black™ tri-metal construction, combining a lead-bronze base layer with a nano-scaled hardening process applied to the Babbitt overlay. This advanced metallurgical design delivers exceptional load capacity and fatigue resistance far beyond conventional race bearings.

Key Features:

• pMax Black™ Tri-Metal Construction — 24% harder than conventional tri-metal race bearings for superior durability
• 10,200 PSI Load Capacity — nano-scaled Babbitt overlay withstands extreme bearing loads
• Lead-Bronze Base Layer — layered tri-metal design engineered for high-load, extended-duration performance
• STDX Size — standard bore diameter with +0.001" extra oil clearance for improved lubrication under race conditions
• Steel Crankshaft Compatible — developed specifically for applications using forged steel aftermarket crankshafts
• Advanced Geometric Features — XP-series geometry complements the pMax Black overlay for optimal oil film retention

King's XP Series bearings are ideal for circle track, drag racing, offshore marine, and any high-performance application producing sustained high loads. Manufactured to tight tolerances, the CR4668XP STDX set delivers the precision fit and reliability that professional engine builders demand.
