King CR4125XPG.026 XPG pMax Black Rod Bearings Subaru EJ20 EJ22 EJ25 +.026mm

Vehicle Fitment

• 1990-2013 Subaru Legacy (EJ20, EJ22, EJ25, incl. Turbo variants)
• 1995-2016 Subaru Impreza (EJ20, EJ22, EJ25, incl. Turbo variants)
• 1998-2013 Subaru Forester (EJ20, EJ25, incl. Turbo variants)
• 2000-2015 Subaru Outback (EJ22, EJ25, incl. Turbo variants)
• 2003-2006 Subaru Baja (EJ25)
• 2005-2006 Saab 9-2X (EJ20, EJ25)
• 2012-2016 Subaru WRX (EJ20, EJ255)
• 2013-2019 Subaru WRX STI (EJ25, EJ257)

Fitment Notes

• Fits all Subaru EJ-series 4-cylinder engines with 52mm big-end rod journal diameter only
• Compatible with EJ20, EJ22, and EJ25 engine families including all turbocharged variants (EJ205, EJ255, EJ257)
• .026mm oversize - intended for cranks reground to +.026mm or builds requiring slightly tighter oil clearance than STDX
• All 8 bearing halves are plain (no dowel pin); verify rod housing bore before ordering
• Phase 2 EJ engines (1999+) with 52mm journal confirmed; verify early Phase 1 EJ20 journal size before use

Features

• XPG lug design eliminates the conventional lug recess, preventing oil escape and maintaining full oil pressure at the journal
• pMax Black tri-metal overlay delivers 24% greater hardness over standard race bearings via a nano-scale molecular hardening process
• 20% higher load capacity than conventional tri-metal bearings - purpose-built for high-boost, high-RPM EJ applications
• Narrowed bearing length prevents dangerous fillet ride on high-radius performance crankshafts
• SecureBond adhesion process bonds tri-metal layers for superior stability under sustained performance loads
• Wall thickness tolerance held to ±0.0001" for exceptional consistency and minimal selective fitting during assembly
• Radialock technology optimizes crush height for secure seating and proper load distribution in the rod bore

Product Description

The King CR4125XPG.026 is a +.026mm oversize XPG-series connecting rod bearing set engineered specifically for Subaru EJ20, EJ22, and EJ25 boxer engines, including all turbocharged variants. The XPG series was developed to address a known weakness in EJ engines - oil starvation at the rod journal under high load - by replacing traditional oil slots with precision oil holes for more consistent, pressure-stable oil distribution. Combined with King's pMax Black tri-metal overlay and SecureBond adhesion, these bearings deliver 20% more load capacity than conventional tri-metal units, making them the preferred choice for high-boost WRX, STI, and Legacy GT builds.

The .026mm oversize designation makes these bearings ideal for engine rebuilds where the crankshaft has been reground to a +.026mm undersize, restoring proper oil clearance without the need for mix-and-match shell combinations. Radialock geometry ensures optimal crush height for secure seating in the rod bore, while the narrowed bearing profile eliminates fillet ride on aftermarket or machined performance crankshafts. Whether refreshing a daily-driven Impreza or assembling a dedicated track EJ build, the CR4125XPG.026 provides the precision and durability required for long-term reliability.
