Well, if made in the USA matters, you may want to reconsider Rubicon Express as a choice in lifts. Now that they are owned by 4WheelParts, I'm pretty sure most of their stuff is made in China like all their other stuff. Of course, when it comes to budget boosts, there really aren't too many made in the USA options. In reality, most any budget boost out there will get you what you're looking for and without any issues. Needless to say, it's hard to go wrong with any of them.
Regarding bumpers, LoD is made in the USA and are a supporter of ours. I have personally run their bumpers and found them to be quality products and ones I would highly recommend. EVO is also a supporter of ours and makes everything in the USA as well and I would recommend them as well. There are other great options out there and if you have something in mind, I'm sure I or others can chime in as to what we think about them.
