I am assuming that you are lifting a YJ since we are in that forum
, so I think a 3.5 BDS softride suspension would be a good starter for you. Your jeep will already do alot without any lift if you gave it a chance
Jeeps are very capable vehicles in stock form and light wheeling is no problem right off the lot. Remember that most jeeps start needing some work to be done to the steering components at or around 4" of lift so unless you want to mess with that area you should stay below that number. If you buy a lift package that requires a drop pit man arm, (read the components to find this out) it means you are messing with the steering geometry and all drop pit mans will reduce your turning radius somewhat.
The BDS softride is a good suspension, skyjacker will beat you to death, and beyond that I would go with Rubicon Express as my lift of choice. Remember that your rear axle (if it is the stock D35) is not very appreciative of tires larger than 33" and using your skinny pedal wisely will make it last. If you are buying wheels make sure you test the back spacing so that you don't get the tire too close to the frame as this will rub and also loose turning radius on your rig.
Generally speaking if you have limited knowledge of the jeep, buy a complete bolt on kit and then try to install it yourself you will learn more this way. PB blaster is your friend, use it generously and things will be easier. I get a lot of jeeps at my place because people either get a bit ahead of themselves and/or want more than their knowledge and skill can handle. I am not saying that is a bad thing, just trying to say know your limitations. A poorly installed lift will ruin your fun in the jeep as fast as anything and will also take a toll on your wallet.
Also don't take anyone's word as gospel, even mine
. Google is your friend and their is an abundance of info on the net, gather several opinions and then apply them as your situation dictates and you should be fine.
