Many rod suppliers are making steel connecting rods out of 300m alloy.
And the best.
There are some practical considerations when choosing a connecting rod.
Most aftermarket steel connecting rods are made from forged steel.
Our engineering team created this new patent pending 3 pocket design specifically for demanding turbocharged supercharged and big nitrous applications.
These connecting rods are ideal for today s high horsepower engines and provide 60 more bending strength compared to common h beam rods.
