Whatever you do, DO NOT go cheap! Plan on spending some cash & have it done right.
We are in the gen 1 Tundra area so he must have a pre 07 Tundra which has plenty of lift options available.I honestly think I'd take the "wait and see" approach. When I lifted my truck, there were only 3 options available: Fabtech, ProComp, or CST. I chose the ProComp because of several reasons:
Price
No Cutting/Welding required
SEMA Award Winner for design
Consesus was that this was generally the best kit for my truck
Now there are countless options for lifting my truck. If I were to do it now, I would take an entirely different approach. Not that I'm dis-satisfied, but since I've installed it, there has since been alot of stuff that has come out, which are not only better (i.e. more travel, heavier duty, etc.), but they are also about the same price as what I paid for mine.
