h3 axle/steering capabilities with 35s?

[Samco Fab]

I think the 4.56 gear is a common upgrade. For more prerunning and desert race situations the steering rack can go away if you really push it, or do something wrong. I would carry a spare rack and tie rod assembly, do the 4.56 gears, and install the bolt on Fox shock upgrade if it were mine. The H3 is pretty tough, the only problem I have seen is the muffler breaks off after a while, I would install a lighter weight muffler.
