Stock steering on a Dana 60 places the tie rod directly in front of the axle, making it extremely easy to bend it. High steer arms allow you to mount the tie rod above the leaf springs, thus keeping it out of harm's way for better clearance. You should also look into crossover steering while you're at it.
Here is a link to ORD's website that explains it better.
