zero rate, 2wd steering box??

[llong66]

I have been reading some of the threads about lifting that some ppl have done and I have a cpl questions. I have a civi half ton that I put a 4" lift and drop pitman arm on, the truck has been cross country several times and has always drove/handled great. My question is what is meant by a zero rate spring? what do they do differently, and why do some ppl go to a 2wd steering box? Whats the benifit in this? THanks alot!

I think the 2wd steering box is for adding cross over steering and the zero rate is a block to attach to the front springs to add 1" and move the axle foward 1 inch.

Go to ORD.Com they have all the info on this.
