Product Details

*To be used with aftermarket pistons with 20mm wrist pins*

IE H-BEAM CONNECTING ROD SET | 144X20
Achieve your performance goals with IE H-beam connecting rods that will make your build a success. IE Rods are designed for strength and reliability to support performance builds up to 600 horsepower and torque. Engineered to be fairly light weight for a high power to weight ratio making them the perfect choice for aggressive street builds.

LEADING BENEFITS

  • Supports far more horsepower and torque than the stock components
  • Keeps your engine reliable for upgraded turbos and superchargers
  • Supports higher RPMs to squeeze out more top end power
  • Safeguards your engine to ensure a successful project
  • Supports up to 600 horsepower and torque (for higher power builds consider IE Tuscan I-beam Connecting Rods)

DESIGN FEATURES

  • Extra strong forged 4340 chromoly steel
  • Made in USA ARP 2000 rod bolts
  • Computer optimized on a specific application basis
  • Honed to exact tolerance on USA made Sunnen machinery
  • Each set balanced to +/- 1 gram
  • Thoroughly quality controlled dimensionally and for material quality  
  • H-beam design optimized to be lightweight and strong for daily driven cars
  • Tanged rod bearings for extra security and reliability
  • Optional rifle drilling for increased wristpin and bushing life

HIGHLY ENGINEERED IN-HOUSE
All IE connecting rods are designed on and per engine application basis for factors such as cylinder pressure and rotating assembly mass. Many other brands simply change dimensions and do not engineer for the specific application at hand. FEA and computer simulation software is used to ensure the highest quality product.

MACHINED & INSPECTED IN USA
The two most important dimensions of a connecting rod are the tolerances and roundness of the crankshaft journals and wristpin bushings. IE Rods are machined in-house on our top-of-the line USA made Sunnen rod hone machine that ensures proper critical roundness. After machine work is finished, every rod set undergoes a strict quality control process to verify all tolerances, weight balance, bolt threads, and surface finishes. Honed to exacting tolerances within 250 millionths of an inch. Multiple QC processes ensure proper clearances.

OPTIONAL RIFLE DRILLING
Rifle drilling is a machining process that adds a small hole directly through the center of the connecting rod. This galley force-feeds oil pressure from the crankshaft journal through the rod to the wrist pin bushing. Providing extra lubrication greatly extends engine life and reduces wear on the wrist pin and wrist pin bushing. Rifle drilling upgrade is highly recommended for street cars that will be driven for extended miles. H beam cross section model details the rifle drilled oil galley for forced pin oiling.

VEHICLE FITMENT
This 144X20 connecting rod set will only work with factory-equipped pistons that use 20mm wrist pins and non-tapered rods. Many 1.8T 20V (06A) and 2.0T FSI (EA113) engines use a tapered rod, for these engines please see our drop-in rod options if you wish to keep factory pistons. Use the piston fitment guide in the technical specs tab to verify factory piston compatibility.

1.8T STROKER KIT COMPATIBLE
Looking to increase the displacement of your VW or Audi 1.8T 20V (06A) engine? This connecting rod set is compatible with stroker crankshafts and 20mm wrist pin stroker pistons for either 2.0L or 2.1L stroker conversions.

CONNECTING ROD FAQ
Are these are a direct replacement for factory rods?

  • This rod set fits several VW/Audi engines with a 144mm journal bore and is a direct rod replacement for engines with a 20mm non-tapered wrist pin. For engine variations with a tapered or different size wrist pin, an aftermarket 20mm piston will be required. Please refer to the vehicle and piston application tables for fitment guides.

Are these connecting rods forged?

  • All Integrated Engineering Connecting Rods are made from extremely durable 4340 material forgings.

Do these rods require any additional machine work for installation?

  • IE connecting rods themselves are machined, balanced, and ready for installation. The engine block may require machine work when installing new rods such as a surface deck and cylinder hone.

When do I need IE Tuscan I Beam rods over H beam rods?

  • IE 4 cylinder H-beam rods are rated for about 600 horsepower and 600 torque (ft/lbs). If you are planning on exceeding these power levels we recommend upgrading to our Tuscan I-beam Rods.

What are the most common reasons for connecting rod failure?

  • Connecting rods are one of the highest stressed components in your engine, and several factors can contribute to a failure. The most common rod failures happen by oil starvation, improper ECU tuning, improper bearing clearances, or installation mistakes. Professional installation of your new connecting rods and ECU tuning is crucial to ensure your IE rods stay inside of your engine block.
