I like the Rancho 4" lift that is actually 5.25". The right backspacing and a little trimming of the front fenders and bumper, and you could run 35x12.5's.
I also like
http://www.bds-suspension.com's 6" lift. Bolt together lift like some of the others, Superlift for one, high quality, usually you can get them for a good price, and you can't beat BDS's warranty:
No Fine Print Warranty
If you are the original purchaser of any BDS product and it breaks, we will give you a new part. PERIOD.
We invite you to compare our warranty to the ones used by the other major suspension companies.
Sounds good to me. I'm planning on running their lifts when I get back to Michigan and am lifting my truck(s). No cash now.
