What types of connecting rods are there?

I-beam connecting rod
I-beam connecting rods owe their name to their resemblance to a capital ‘I’ when you cut them apart. Connecting rods with an I-beam are the most common type of connecting rods and thus the ones most often used in series production. They are cheap to manufacture and generally withstand more than they would actually need to in standard engines. Standard I-beam connecting rods are often heavier than those with an H-beam. With our high-performance I-beam steel connecting rod (like in this set for the 1.8T), however, this generalisation doesn’t apply. These are very lightweight and often sustain up to 1,000 hp, which is mainly due to the fact that they are milled out of solid, high-strength steel.

X-beam connecting rod
Connecting rods with an X-beam are the latest achievement from connecting rod manufacturers. They are like a sort of hybrid between I-beam and H-beam and combine the best properties of their predecessors. These connecting rods have a large cross-section, thereby distributing the tension across the entire connecting rod. Thanks to their high rigidity and crack resistance as well as minimal weight, they are basically made for racing. You can get the BAR-TEK X-beam connecting rod for your 2.0L TFSI, for example, as a set.

Which connecting rods for which engine?
The rule used to be: under excessive strain, connecting rods can easily tear apart, since the force is exerted in a linear manner. How strong the tensile force on a connecting rod is depends primarily on its cross-section and material. With charged engines, in which compression forces act on the connecting rods, this is different. Here, the connecting rods bend, since these forces are not linear. The shape of the connecting rod plays a greater role here: An H-beam connecting rod is lighter than its I-beam counterpart and can better minimise these forces. It is therefore sturdier when exposed to compression forces and thus better suited for charged engines.

We are now able to produce connecting rods with different cross-sections and materials for all applications. An H-beam connecting rod is thus not necessarily better or worse than one with another form. It all depends primarily on the design and material.

That’s why you should make sure that when choosing your connecting rods, you pay attention to what performance level they are designed for. Also take a look at the material and don’t use connecting rods with poor quality. These can quickly tear or bend, ruining your entire engine.
