2003-2013 King Mazda MZR 2.3L 16V / Ford Duratec 2.3L 16V (Size .026) Connecting Rod Bearings (Set of 4)

King CR4507XP.026 connecting rod bearings provide exact fit for Mazda MZR 2.3L 16V and Ford Duratec 2.3L 16V engines in Focus Fusion Mazda3 Mazdaspeed CX-7 and similar models. This set of 4 undersize .026 bearings ensures proper clearance in rebuilt or high-performance engines. Designed for reliable operation under boosted or high-rpm conditions with advanced materials for extended service life.

Key Features

  • pMax Black™ Overlay: Lead-tin-copper overlay with nano-composite layering resists wear and scuffing during high-load events like turbo spool-up or track use.
  • Precision Sizing: .026 undersize controlled to microns for consistent oil film and rod journal contact in 2.3L engines.
  • Oil Spill Notches: Extra oil flow grooves maintain hydrodynamic lubrication even at extreme angles and speeds.
  • Tri-Metal Construction: Steel back with copper-lead interlayer and protective overlay handles heat and pressure in performance applications.
  • Tapered Edge Design: Reduces bearing whip and flexure for stable crankshaft operation in rev-hungry 2.3L builds.

Product Notes

  • Verify rod journal size before install. .026 undersize suits machined cranks needing additional clearance.
  • Pair with King main bearings for complete bottom-end refresh on Duratec or MZR engines.
  • Packaged in protective sleeves to prevent contamination during storage and shipping.

Installation Notes

  • Professional installation recommended.
  • Plastigage clearances and mike rod journals for .0015-.0030 inch target on .026 size.
  • Compatible with stock rods. no special hardware required for standard 2.3L setups.
