King CR4616XPGC0.25 XPG pMaxKote Rod Bearing Set for Subaru FA20 Toyota 4U-GSE

Vehicle Fitment

• 2015-2021 Subaru WRX (VA Platform, 2.0L FA20F Turbo, AWD)
• 2013-2020 Subaru BRZ (ZC6 Platform, 2.0L FA20D Naturally Aspirated, RWD)
• 2014-2018 Subaru Forester (SJ Platform, 2.0L FA20F 2.0XT Turbo, AWD)
• 2013-2016 Scion FR-S (ZN6 Platform, 2.0L 4U-GSE Naturally Aspirated, RWD)
• 2017-2020 Toyota 86 (ZN6 Platform, 2.0L 4U-GSE Naturally Aspirated, RWD)

Fitment Notes

• Fits the Subaru FA20 and Toyota 4U-GSE 2.0L boxer-4 engine only - does not fit FA24D or FA24F engines
• Does not fit 2022+ Subaru BRZ or 2022+ Toyota GR86 - those models use the FA24D engine with different journal dimensions
• CR4616XPGC0.25 denotes the 0.25mm undersize - intended for engines with crankshafts reground 0.25mm undersize; confirm journal diameter before ordering
• Fits both naturally aspirated (FA20D) and turbocharged (FA20F) variants of the FA20 engine

Features

• XPG-Series tri-metal construction with copper-lead substrate, nickel barrier, and lead/tin/copper Babbitt overlay over precision steel backing - 20% higher load capacity vs. standard XP bearings
• Unique lug (RadiaLock™) design eliminates the conventional lug recess, preventing oil escape and maintaining full oil pressure at the bearing surface
• Factory-applied pMaxKote nano-composite polymer coating over pMaxBlack overlay - enhances seizure resistance, cavitation resistance, and wear protection without altering wall thickness
• SecureBond adhesion process delivers superior overlay stability and fatigue resistance under high-RPM and sustained high-load conditions
• Bull's Eye Tolerance™ wall thickness control holds tolerances to ±0.0001 in. for consistent shell-to-shell fitment and proper oil clearance

Product Description

The King CR4616XPGC0.25 is a 0.25mm undersize XPG-Series pMaxKote coated connecting rod bearing set engineered for the Subaru FA20 and Toyota 4U-GSE 2.0L boxer-4 engines. Built on King's advanced tri-metal XP platform and enhanced with the proprietary RadiaLock™ lug design, these bearings eliminate oil loss at the lug recess - a critical advantage in high-performance and forced-induction applications where maintaining full oil pressure at the rod journal is essential. The factory-applied pMaxKote nano-composite polymer coating provides an additional layer of protection against metal-to-metal contact, cavitation, and oil starvation without changing the bearing's precision wall thickness.

This 0.25mm undersize set is intended for engine rebuilds where the crankshaft has been reground 0.25mm undersize to restore the rod journals to a clean, round surface. Confirm your journal diameter with a micrometer before ordering. Ideal for performance builds, high-mileage rebuilds, or any FA20/4U-GSE application where maximum bearing durability and precision fit are required - from street-driven BRZ and FR-S builds to full WRX competition engines.
