The Cummins also has 200 lbs. more steel over the DMax.

Even though the Cummins has two fewer holes, the rod's massive construction looks like quite a bit more than the 33% difference one would expect from the different cylinder configurations.

Makes ya feel a lot safer abusing it!

Hahahahaha Could not agree more. I have fears on my dad's Powerjoke he put a banks kit on at less than 2k miles that something will go wrong, that is directly or closely related to the banks kit.

As for my truck, I fear nothing will go wrong, if I do anything to it.

Though I just noticed just the other day I have a FUEL leak from ON/IN around the fuel filter. Didnt think it is time to change the bugger or what, though come a few spare minutes time that thing and the gasket will be changed out. Hopefully ir is nothing more than just that.

Is it just me or does the PSD rod look wider? Isn't girth what you really want?

Longer and thicker is stronger.

It's longer but it don't look thicker. I'd think shorter/thicker would be stronger than longer/thinner.

Guys,

There are good and bad attributes to both the long and short rods! There simply is no such thing as one rod that is better than the others.....differing applications will dictate the optimum design.

One thing to remember about the shorter rod is that it will have to be beefier than the longer rod to hold the same loads since it is always operating at greater angles than the longer rods and side loading the pistons more. Shorter rods will need to be stronger at the connecting points and longer rods will need stronger beams if you must generalize!

Well, I think the Cummins rod certainly looks much stronger.

I just think there's such an obvious difference in the amount of steel used to make the rods that I don't see how the Cummins rod couldn't be stronger and more durable.

Lets not forget the 2001+ 7.3 and 6.0 power stroke have powder metal rods that snap with anything more than a chip (they shoulda stuck with the forged rods)
