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.
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 IE’s 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.

Before You Begin
Prepare a clean indoor work surface such as a stainless bench. Unpack your rods, remove the rod bolts with an 11mm 12 point socket, and split the bearing caps from the rods. Use brake cleaner with a lint-free rag to remove all rust inhibitor oils from the surface, threads, journals, bushings, and rifle drilling channel (if present). Visually inspect all rod surfaces.
- Tools & supplies
- Socket wrench
- 11mm 12 point socket
- Torque wrench (quality & calibrated)
- Dial bore gauge
- Secured bench vise
- Bolt stretch gauge (optional)
- thread tap/thread gauge (optional)
- ARP bolt lube (supplied with rods)
- Carb cleaner
- Lint-free rags
Verify Clearances
Before installing your connecting rods into the engine, all critical clearances should be measured and recorded. Label each rod, bearing set, crankshaft journal, and wrist pin 1-4 with a marker to keep track of your measurements. Using a vice, assemble the rod with the rod bearings, rod bolts, and ARP assembly lube. Torque the rod bolts using the torque procedure on this page. Make sure the printed numbers on the rod and rod cap match and are installed on the same side.
Measure clearances with a quality bore gauge and micrometer only, do not use a Plastigage type product.
- Using a quality bore gauge and micrometer, record the following measurements:
- Wrist pin diameter
- Wrist pin bushing bore
- Wrist pin clearance (Bore minus diameter | Target:.0003"-.0005")
- Rod journal (w/bearings)
- Crankshaft journal diameter
- Journal clearance (Bore minus diameter | Target:.0015"-.0025")
Torque Procedure
Accurate rod bolt pre-load is required to ensure proper bore clearances and roundness of the connecting rod big end for both measuring and final installation of your connecting rods. Before you begin, clean the rod mating surfaces and remove all packaging oil from the threads and rod bolts.
Before you final stretch your rod bolts, it’s important the bolt and rod threads are fully seated.
The final torque spec is.006" (stretch gauge) or 50 ft/lbs (torque wrench) with ARP assembly lube. The preferred method of measuring bolt load is with a stretch bolt gauge.
Do not exceed rod bolt stretch/torque. If bolt stretch is exceeded, replace rod bolts with new ones.
Do not install bolts dry or with any other lubricant than the supplied ARP assembly lube.

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.
All Integrated Engineering Connecting Rods are made from extremely durable 4340 material forgings.
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.
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 IE recommends upgrading to IE’s Tuscan I-beam Rods.
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.
