For use in:
ALL VW / Audi VR6 Engines with 84mm+ bore (Stock 3.2L is 84.0mm)
164X20 H Beam Rods With 3/8" Bolts
These rods are specialized for 84mm+ VR6 and VR5 engines such as the R32. The larger bore allows for a stronger 3/8" rod bolt.
Available for use with custom R32 VR6 Pistons
The H Beam VR6 forged connecting rods are a perfect match with available custom pistons, for the R32. This combo creates a stout bottom end tested well over 700HP+ and perfect for boosted engines.

Integrated Engineering is proud to manufacture the highest quality connecting rods available for European
applications, at a reasonable price. This is accomplished through careful design, manufacturing, and quality
control processes. With hundreds and hundreds of sets of VW and Audi connecting rods in stock, we are
your specialist supplier with the inventory and knowledge to make your project a success.
Quality through design
One of the hallmarks of a high quality connecting rod is its strength to weight ratio. Anyone can create an
extremely strong rod out of a huge chunk of steel. Creating one with a reasonable weight that works well in
today's high rpm european applications, and holds up to a lifetime of torture is another story.
In order to create this balance of strength and light weight, an H beam design is utlized. The design is validated
and optimized using modern CAD drafting and FEA analysis techniques. These techniques ensure the rod is as
light and strong as possible.
The material specification and treatment is equally important to producing a quality connecting rod with a high strength to
weight ratio. Our steel rods feature 4340 Chrome Moly steel, formed into shape using a 2 piece forging for the highest
possible fatigue life. The material is multi-stage heat treated to ensure the highest possible fatigue strength as well as good
dimensional stability. This feature ensures that our big ends stay round for a lifetime of bearing trouble free service.
Following this pattern of high quality, ARP 2000 rod bolts are standard in all of our applications, while they are an upgrade at
additional cost in many of our competitors.

All of our H Beam Forged rods are available in a rifle drilled option. Rifle drilling will put a small pathway through the center of the rod from the bearing to the wrist pin. This pathway allows pressurized oil from the rod bearing to feed extra oil to the wrist pin itself, causing less wear and friction between the rod and piston and increasing the life of the internals. We highly recommend this option in high horsepower and increased rev applications.
You can select the rifle drilled option at an additional 25.00 a rod.
