Eagle H-Beam Rods for 4B11 Evo X

Firstly, BUY Eagle H-Beam Rods Evo X for the Mitsubishi 4B11T. Upgrade the bottom end of your Mitsubishi Evolution X with Eagle H-Beam Rods for 4B11 Evo X, designed for high-performance and competition-oriented 4B11T engine builds. Manufactured by Eagle Specialty Products, these connecting rods use a forged 4340 steel construction and an H-beam design developed for high horsepower, high-RPM, and forced-induction applications. The standard 3D version is supplied with 3/8-inch ARP 2000 rod bolts and is rated by Eagle for applications up to approximately 900 horsepower in four-cylinder turbocharged engines.

The Eagle CRS-5659M3D rods are specifically dimensioned for the Mitsubishi 4B11 engine used in the Evolution X. Each set contains four weight-matched connecting rods, with a 5.659-inch center-to-center length, 0.906-inch pin size, and 2.046-inch rod journal specification. The small ends are bushed for full-floating piston pins, making these rods suitable for performance engine combinations using compatible floating-pin pistons.

Firstly, the forged 4340 steel construction provides a substantial upgrade over standard connecting rods for a performance-oriented engine build. Secondly, the H-beam profile combines strength with controlled weight for demanding turbocharged applications. Thirdly, the included ARP 2000 fasteners provide a high-strength rod-bolt solution for engines being assembled with increased boost and power.

Eagle also offers an Extreme Duty CRS5659MXD version using ARP Custom Age 625+ bolts. This is a separate specification from the standard CRS5659M3D and should be selected according to the intended engine build and builder requirements.

Eagle H-Beam Rods for 4B11 Evo X Performance

The connecting rods are one of the most important components in a high-performance engine because they transfer combustion force from the pistons to the crankshaft. For a turbocharged 4B11T, upgrading the rods can become an important part of building an engine intended for substantially higher power than a standard configuration.

Eagle’s H-Beam design is intended for high-horsepower and high-RPM competition engines using forced induction, nitrous, or other demanding combinations. Eagle states that its sport-compact H-Beam rods equipped with 3/8-inch ARP 2000 bolts are recommended for up to approximately 900 horsepower in four-cylinder turbocharged applications. This is a manufacturer’s application guideline, not a guarantee of performance, and the actual capability of an engine depends on the complete combination, calibration, assembly quality, operating conditions, and other components.

The rods are manufactured from forged 4340 steel and undergo machining and shot-peening. Eagle also states that the rods are weight-matched, helping provide consistency between cylinders during engine assembly.

Vehicle Fitment

These Eagle H-Beam rods are designed for:

• Mitsubishi Lancer Evolution X 2008
• Mitsubishi Lancer Evolution X 2009
• Mitsubishi Lancer Evolution X 2010
• Mitsubishi Lancer Evolution X 2011
• Mitsubishi Lancer Evolution X 2012
• Mitsubishi Lancer Evolution X 2013
• Mitsubishi Lancer Evolution X 2014
• Mitsubishi Lancer Evolution X 2015
• Mitsubishi 4B11 / 4B11T engine applications

The CRS5659M3D is specifically catalogued by Eagle for the Mitsubishi 4B11. Always confirm piston, wrist-pin, crankshaft, and engine configuration compatibility before ordering.

Standard H-Beam vs. Extreme Duty

Eagle provides more than one fastener configuration for its 4B11 H-Beam rods.

The CRS5659M3D uses 3/8-inch ARP 2000 bolts and carries Eagle’s approximately 900-horsepower recommendation for four-cylinder turbo applications.

The CRS5659MXD Extreme Duty version uses 3/8-inch ARP Custom Age 625+ bolts and incorporates additional surface polishing intended to improve fatigue life. Eagle does not establish a formal power rating for the XD version, so its capabilities should not be treated as a guaranteed horsepower figure.

Choose the specification based on your target power, RPM, boost level, intended use, and engine builder’s recommendations.

Installation & Engine Building

Professional engine assembly is strongly recommended. Connecting rods require accurate inspection and correct installation, including proper bearing clearances, piston-pin compatibility, rod orientation, crankshaft journal measurements, and correct rod-bolt installation.

Eagle specifies 43 ft-lbs using ARP moly lubricant only for the CRS5659M3D rod bolts. Always follow the current manufacturer’s instructions supplied with the rods and the applicable ARP fastener procedures rather than relying solely on general torque specifications.

Before final engine assembly, your engine builder should verify the rods, crankshaft, bearings, pistons, wrist pins, and cylinder clearances as a complete combination.

Package Includes

• 4 × Eagle forged 4340 steel H-Beam connecting rods
• 3/8-inch ARP 2000 rod bolts
• Bushed small ends for full-floating piston pins
• Weight-matched rod set

Pistons, piston rings, bearings, crankshaft, and other engine components are not included unless specifically stated in the product listing.
