The H-beam design is the workhorse of our connecting rod product line. This design features strength, durability, stiffness, and rigidity. IE H-beam Connecting Rods are a great upgrade over weaker factory units.
All IE rods are designed specifically for the application using relevant cylinder pressure and other application-specific factors. We put our vast European engine knowledge to use when designing each application.
Honing the connecting rod big end in-house on state of the art equipment ensures the tolerances are set correctly to ensure proper bearing operation. Lesser quality rods are often not honed with the same attention to detail.
Made from strong and durable 2 piece 4340 forgings these rods will withstand almost everything you can throw at them.
All IE rods come standard with ARP 2000 rod bolts. The rod bolts included in every set of IE rods are stamped with the letters "IE" as a way to ensure you have a genuine set of IE rods.
*The following torque spec is for the included ARP 2000 3/8" rod bolts using the included ARP assembly lubricant only. Do not follow this guide using ARP +625, other assembly lubricants, or alternative bolts.
The preferred method of measuring bolt load is with a stretch bolt gauge. The included ARP 2000 bolts need to be tightened and measured to .006” of stretch using the included ARP assembly lubricant.
When using a high-quality torque wrench, first verify the torque wrench has not been dropped and is properly calibrated. A un-calibrated torque wrench can lead to under/over torque and rod bolt failure. Torque each rod bolt to a final torque of 50 ft/lbs. We recommend torquing the bolt, breaking it loose, and re-torquing the bolt 3 times per bolt. This ensures proper rod bolt stretch and that the rod cap is fully seated. Do not exceed 50 ft/lbs. This torque spec is based off the included ARP assembly lubricant.
Connecting rods are some of the highest stressed components in an engine and thus require extreme attention to detail to ensure proper operation and reliability. Integrated Engineering ensures the success of your next engine build by putting each set of connecting rods through a rigorous quality control process. For years Integrated Engineering H-beam Rods have been an integral part of delivering the power that the highest powered turbo setups and race engine demand.
Extra attention has been paid to even the smallest details such as the bearing tangs, wrist pin fit, and big end side clearance, providing a level of fit and finish not found anywhere else. Each and every set is finish machined and honed in-house for perfectly round and on size big-end bores, resulting in the industry's lowest failure rates. All rods in this series feature generous wrist pin oiling and optional rifle drilling. One of the hallmarks of a high quality connecting rod is its strength to weight ratio. In order to create this balance of strength and lightweight, our optimized H beam design is utilized and validated using modern CAD drafting and FEA analysis techniques. These techniques ensure the rod is as light and strong as possible, perfect for today's powerful and high rpm European applications.

Calico/ACL performance coated rod bearings - IE Part Number: CAL-4B1606HC5
These rods fit I5 engines found in many Audi early chassis. These are a direct replacement for engines with factory or aftermarket pistons with 20mm wrist pins.
We recommend installing the bearings tangs facing the exhaust side of the engine.
Yes, all Integrated Engineering Connecting Rods are made from tough and durable 4340 forgings. These forgings far exceed the quality of most factory rods that are typically made from powdered metal as a cost saving measure.
These rods require aftermarket 20mm wristpin pistons, additionally, we recommend at a minimum that you should use a new set of connecting rod bearings when installing rods.
IE connecting rods are delivered to you in "ready to install" condition. Other engine machine work may be required though when rebuilding an engine, such as decking the block or boring and honing cylinder walls.
Since IE rods are sold in balanced sets this is not required. For extreme performance application, this can still be done if desired.
The maximum RPM limit can be affected by many factors. In this application, we suggest not exceeding 8500 RPM with ARP 2000 bolts. If you plan on exceeding this RPM level, consider upgrading to ARP 625+ bolts.
Generally speaking, high RPM conditions put the most stress on rod bolts as the rod and cap are literally being pulled in opposite directions. If you plan on pushing your engine far past factory redline or 8500 RPM we would suggest upgrading to 625+ ARP bolts.
Many high horsepower VW and Audi vehicles use IE rods. We rate our 4 cylinder H-beam rods for 700+ HP/ft-lb TQ. If you are planning on exceeding those levels we recommend upgrading to our Tuscan I-beam Rods.
We stock several high-quality piston options to suit your specific needs and to match our connecting rods. To see what we have, check the additional hardware tab.
As one of the highest stressed components in the engine there are several things that can contribute to a failure. The most common failure is caused by improper installation followed by improper tuning. We recommend that you seek professional help for both installation and tuning. Oiling system health is also essential to ensuring save engine operation. Momentary oil starvation can result in spun rod bearings and engine failure. In extreme applications also be sure that you are using heavy duty wrist pins. On many of the pistons we offer we either include stout wrist pins or offer them as an upgrade.

Products are warrantied by their manufacturer. Eurosport Performance is an authorized reseller: every part we sell is covered by the manufacturer's own warranty, with its own terms and duration. Claims go through us, so you deal with Eurosport Performance rather than a form on the brand's site, but whether a claim is accepted is the manufacturer's decision.
|
Manufacturer terms apply
Duration and coverage are set by the brand and differ from one to the next: some cover one year, some a lifetime, some only the original purchaser. The brand's warranty page is the reference; ask us if you cannot find it.
|
We file the claim for you
Contact us with your order number, photos and a description of the issue. We open the claim with the manufacturer, follow it up, and arrange the repair, replacement or credit they approve. The manufacturer decides whether the claim is accepted.
|
|
Fitment guarantee: North America only
We guarantee fitment for vehicles sold in the North American market. Vehicles from other markets are out of scope; specifications differ, and it is the customer's responsibility to confirm compatibility before ordering.
|
No warranty on tuning files
ECU and TCU tunes and other software files are sold without warranty and are not returnable once delivered or flashed. Tuning can affect your vehicle's factory warranty; please read the brand's terms before purchasing.
|
|
Proof of purchase
Your Eurosport Performance order is the proof of purchase every manufacturer asks for. Keep the order confirmation; it is also in your account on the site and in the SPECD app.
|
What is usually not covered
Damage from improper installation, modification, abuse, racing or an incorrect application for the vehicle, and normal wear items such as pads, clutch discs and filters. Shipping and labour are covered only when the manufacturer's terms say so.
|
It is the manufacturer's warranty for that product. Where the brand publishes it, we note it in the description; otherwise contact us before ordering and we will confirm the exact terms with them.
Stop using it if it is a safety-related part, then contact us with your order number, clear photos, and when and how the issue appeared. Do not return anything until we confirm the claim; manufacturers often require an inspection or an authorization number first.
The manufacturer. We prepare and submit the claim, provide the proof of purchase and push for a fair outcome, but acceptance, replacement or credit is their call under their terms. We pass their decision on to you as soon as we have it.
It depends on the manufacturer. Simple cases are approved in days; claims that need the part inspected can take a few weeks. We keep you updated at each step and push when it drags.
No. Tuning files are software; once delivered or flashed they cannot be returned, and they carry no warranty from Eurosport Performance or, in most cases, from the tuner. Support for the tune itself (revisions, flashing questions) comes from the tuning brand under its own terms.
No. Our fitment guarantee covers vehicles sold in the North American market only. European, Japanese and other market vehicles can differ in engines, electronics and dimensions, and a part listed for the North American model is not guaranteed to fit. If you order for one of these vehicles, confirming compatibility is your responsibility, and fitment issues on such vehicles are not covered by returns or warranty.
Labour is not covered unless the manufacturer's terms specifically include it. Having the part installed by a qualified shop protects your claim: improper installation is the most common reason a manufacturer declines.
No. Returns cover unused parts you no longer want, under our refund policy. Warranty covers a part that fails in use, under the manufacturer's terms. If you are unsure which applies, contact us and we will point you to the right one; please do not open a bank dispute, as it pauses both processes.
Questions about coverage before you buy? Email us with the product and your vehicle and we will confirm the manufacturer's terms.
