I'll be out in New Castle visiting family this weekend. Tomorrow we'll be driving to Grand Mesa/ Cedaredge area. I can bring them if you want to meet up. Let me know.
Either or.
They are designed to work with the factory springs, but you could use springs like these and they would work fine. In the first photo you can see the 4 grooves in the shock body for the c-clip to mount the spring perch. If you use stock springs you'd want it set on the top setting...
I have a brand new set of Eibach Pro-Truck shocks for 4th/5th gens for sale. Provides 0-2.5" of lift with stock springs. Price is $180.00 shipped to anywhere in the lower 48. $160.00 for local pickup.
Maybe I missed it somewhere, but which Toytec kit did you get? There are some that you will need a spring compressor for and some you wont.
EDIT: After a little research I'm guessing you went with this kit http://toyteclifts.3dcartstores.com/Toytec-lift-kit-for-TRD-Pro-4Runners_p_1438.html
Yeah...
You're correct. The link I posted nearly 8 years ago no longer works. Here is an updated link to their site. Not sure if they are even still in business though.

There are a lot more bumper options out there now that weren't available 8 years ago. Check out CBI fab, Addicted...
Take these images and head to your local fab shop and tell them you're looking for a deer proof bumper. Keep in mind, if they try to charge you more than $300, it's a rip off and you should go elsewhere.
I've always liked Gerdo's modification to the stock uppers. He welded a threaded shaft to one side and a nut onto the other. This allows the ends to rotate without resistance.
