You witnessed me break a d44 shaft but my cv's survived. Yeah I broke a tie rod too, but thats what the tie rod shields are for.


True, but the steep incline of the trail you were on kept the front end light and transferred most of the weight over the rear. And when the tie rods let loose, that absorbs force otherwise transfered to the CVs. if your tie rods held, its possible the CVs could have gone.

I was running tie rod shields when I'd break CV's with 33's. I was also running them while I had the 35s. I'm not trying to give 35's a hard time, but there are enough stories here about people trashing the IFS routinely with smaller tires. 35's is only going to make that worse. 37's I'd say don't have much of a place with the stock IFS if you wanna wheel your rig at the level its capable of. street, sure, not a problem. mud/snow often require lots of wheel speed, which you'll be fine with until you catch a little bit of traction and parts start exploding.

i've seen enough chevy's running 44's on stock 10-bolts and jeeps running 37's on stock D35s... an isuzu IFS on 37's is not all that different IMO. can it be done? sure. is it a good idea/will it ever be reliable? nope.
