These are the Intengineering rods. Basically the same design.

Are these the ones they list for the rabbit? How's the fitment? Are they identical dimensions to the GTD rods?

Tight quarters, but it doesn't come closer than this, perigee at about 2mm away from the squirter mount tab. (As seen from the intermediate shaft...bad photo angle; it looks closer than it really is.)

I know this is late - but.

The OTHER difference is that the intermediate shaft gear will have to be massaged because #4 rod will possibly smack the driver side edge of it. rotate the assembly with the shaft in to check.

This is what they used to have to do in the 1.8 8v and 2.0 aba to put monster rods in them back in the day.
Sadly, integrated engineering had not test fitted on ahu /1z so customers like you got caught up in that mess. What thier site shoulkd say if it does not already is "Direct fit for ALH TDI ONLY" m* may fit earlier models with modifications.

That's high performance parts though, always a trade off.

The first version of IE's forged ALH rods needed block clearancing even in ALH engines, so it may be that you got an early version and the block internals are the same.

Or: I built up my most recent ALH with IE's newest design and they fit perfectly but just...all that extra beefiness has gotta go somewhere.  So if there are even subtle differences in the blocks that doesnt show when using stock rods I can see how using bigger rods would make it apparent.

Having said all that, they are beautiful rods, aren't they?!

That's right, I put everything back together and it STILL didn't want to turn all the way around, I finally figured out that it was hanging up on the intermediate shaft. I couldn't actually see what was going on until I popped out the shaft galley freeze plug at the flywheel end of the block.
It appears to hit the drive gear.
I did some shaving on the shoulder of the rod to get it to clear... there goes my matching balance, but oh well, at that point I didn't care any more. Hopefully a few grams won't be noticeable on a low-rev motor.

Thanks for bringing this up, I forgot to add any updates after that issue.

they will fit just do lots of grinding. i just did the same thing last week with my AAZ.
