Eagle CRS5876E3D 4340 H-Beam Connecting Rods for 2015-2025 Ford 2.3L EcoBoost

Vehicle Fitment

• 2015-2025 Ford Mustang / Ranger / Explorer / Focus ST / Everest EcoBoost (2.3L I4, turbocharged, FWD/AWD/RWD variants)

Fitment Notes

• Requires full-floating piston pin application
• Compatible only with Ford 2.3L EcoBoost engines (turbocharged 4-cylinder); not compatible with 2.0L, non-EcoBoost engines
• Must use ARP moly lube when torquing rod bolts

Features

• Forged SAE 4340 chromoly steel for high strength and fatigue resistance
• H-beam design for improved stiffness under high load
• Shot-peened and fully machined surfaces to reduce stress risers and improve durability
• Weight matched set (± around 1-2 grams typical among rods in the set)
• Equipped with ARP 2000 3/8" rod bolts
• Center-to-center length 5.876" (≈ 149 mm)
• Bushed for full-floating piston pin design to allow high-RPM / high-performance builds
• Rated for high power (commonly used in turbocharged competition use up to ~900 HP in 4-cyl applications when properly built)

Specifications

• Rod length (center-to-center): 5.876" (~149 mm)
• Pin size (small end): 0.886" (~22.5 mm)

Product Description

The Eagle CRS5876E3D connecting rods are a high-performance upgrade for the Ford 2.3L EcoBoost turbocharged engine (2015 through 2025). These rods are forged from SAE 4340 steel, feature an H-beam profile, shot-peened and fully machined for precision, with weight matching to ensure balanced operation even at high RPMs. The small end is bushed for full-floating piston pin use, maximizing durability under the increased stress of forced induction and competition tuning.

These rods are intended for builds needing strength beyond stock. They are commonly used in Mustangs, Rangers, Focus ST, Explorers, and other EcoBoost vehicles running upgraded turbo, high boost, or high RPM applications. When installing, use ARP moly lube on the ARP 2000 bolts, torque to 43 ft-lbs, and ensure full-floating piston pins are used. Fitment is confirmed through 2025; 2025 included. This is not for lightly modified use - it is targeted at performance/tuner builds demanding reliability under stress.
