Oh yeah...and here's the reasons why.
You will get some type of warranty with a new lift.
All necessary pieces/hardware will (or should) be there.
Get cool stickers to put on your windows...gives you more horsepower. /forums/images/graemlins/grin.gif
What to look for: Well, the best/most common lifts used by the members here are Rough Country (which I have), Tuff Country, Skyjacker, Pro Comp, Superlift, etc. If you want the best out there, I've heard Tuff Country EZ-ride springs are the best. To create less hassle in the future - buy a system (with rear springs - not blocks). Make sure you get shocks to go along with it. And a raised steering arm. Height...4" will definitely allow 33" tires, and if you go with Tuff Country EZ ride, that's the biggest I can suggest going because they are flexy springs and you'll put a tire into your fender if you go bigger. Also, depending on if you go with Tuff Country 4" ez ride, you may want to get extended front brake lines.
I think I covered the basics. Any more questions, just ask, I'm glad to help.
