So I guess that begs the question, if you are removing the track bar what design changes are you going to make to the suspension and steering to contend with the bump steer ?

Am I reading that correctly , you don't understand why your truck has a certain suspension / steering component so you are just going to remove it ?

it is basically a bandaid to help antiquated technology achieve something resembling acceptable handeling.
A simplified explanation is that your suspension travels in a arc, your steering also follows an arc, the trac bar keeps the alignment of the suspension and the steering on a close enough plane during their movement so that it does not change the steering angle as the suspension cycles. When your suspension travel changes the steering angle it is called bump steer.. Sorta self defining. Hit a bump and the steering angle changes.
This is why when a lift is installed a new track bar mount is used that keeps the drag link and track bar parallel.

bumpsteer is when your suspension compresses and causes the draglink from your steering arm to be pushed in turn causing the spindle to rotate on the ball join or king pin making your vehicle turn with the suspension cycle.
i honestly think trac bars on a non lifted leaf spung vehicle are someones feel good moves at safety, when infact i think they may cause a vehicle to roll over easier in a high speed turn due to binding of the suspension. but thats just a wild theory.

I would still like to know however, would the shackle in the front and larger block in the back work without any other mods? Is there anything wrong with that?

I think this is exactly what I'm going to do. I want the no step look more than anything but with those steps Wendy could get in easier because their height can be adjusted! That is a perfect 8 month purchase item!

I can't say about the rear or front if anything would be needed.

I would think that you would "need" 
or want larger tires (like all of us would) after that and it wouldn't be just a small lift. I think the amp running boards is your best option to get the look you want.

Let us know how that turns out- I'm pretty sure Ford wouldn't put ANYTHING on these trucks that wasn't needed (except for the weight thingy that hangs down under the frame).
Hell, mine didn't come from the factory with a rear sway bar; and I KNOW it needs that to be driven safely...

Shackle mods = depends on how much castor you currently have and how long of shackle you use. You will need an alignment afterwards and then whatever mod is required to get the castor back in spec.
