Their camber cure uppers are super expensive and only fix one issue.
I bought the relocated upper control arm mounts for mine, but before that I just took a rotary tool with a cutting bit and notched the slots enough to get the alignment perfect. The camber control uppers also may give you the ability to align the truck correctly, but it doesn't fix the geometry problem that lowering creates, which is what is giving you the bumpsteer. The only way to fix the bumpsteer is to correct the geometry.
Getting the geometry perfect is pretty much impossible without major cutting/welding/reworking the entire suspension, but you can make it better. Upper control arm relocation brackets work wonders and will get the uppers back to parallel easily on a 3" lowered truck. Then you have to address the tie rod angle, which causes most of the bumpsteer problems. There are a few bumpsteer kits on the market, but when I was doing my research, it seems that they all had problems with durability on trucks that are actually driven a lot so I went another route:
I took my spindles and had them reverse reamed at a 4WD shop. This kind of work is common practice on Jeeps and other lifted trucks, so they've usually got the tools to accomplish the job. You can buy the reamer and do it yourself, but the reamer was over $75 everywhere I looked and they only charged me $100 to do it at the shop. They did require me to bring the spindles to them, they would not do it on the truck for insurance reasons. I then swapped the tie rod from the top of the spindle to the bottom, which brought the tie rod angle much closer to being parallel with the lower control arms and improved the bumpsteer to the point where it wasn't noticeable. When put on a bumpsteer gauge, it still has some but it doesn't try to yank the truck like it used to.
Then I found an awesome alignment shop that specialized in custom cars and gave them the specs that I wanted it aligned to. This is a lot of work and money, but it really made the truck drive like factory again. My next project is to extend the upper shock mount to give me some more travel while allowing me to buy an off the shelf shock designed for a lowered truck, even though I'm beyond the range that they offer.
