I'm looking at different lifts online and my first question is,what is the difference between a kit and a system?

Second question is,what is a good lift (at least 6") that doesn't cost an arm and a leg?I was looking at sky jackers and it's $1700 and still has options to add,I don't know if they're extras or you actually need them,I'm new to adding lifts. The only lifted truck I've had I bought that way.

Third,would a 6" lift be enough for 40" tires on a 92-97 F-350?

Fourth,what is a "nitro shock" and what is a "hydro shock"
Sorry for all the questions.

This is the site I was looking at Suspension Lift Kits, Save up to 30% | 4WheelOnline.com

 

1)From every place I've seen, they just interchange the word kit and system. However, after looking at the link you put there, the Kit has lift blocks in the rear that you add (unadvised, as you already have a 4" block in the back) and the System has replacement rear springs, so you remove yours and put theirs in.
2)Sky Jacker stuff is usually pretty tough, and a lot of times, you get what you pay for.
You need the drop pitman arm on a lift that big to correct your steering. The steering stabilizer is really optional, but with 40" tires on there, you may want to run at least a single one to take out some of the jerkyness of the wheel.
3)Yes a 6" lift is plenty to clear 40" tires. The only problem you may run into, is you may have to trim your front bumper a little, but I think you will be high enough that you won't have to do that.
4)As far as I've read based on their site, the nitro shock is meant for more offroad use than the hydro shocks are. I have nitro shocks (ranchos) on my truck and I like them.

 

Thanks man,you've helped me a lot.
Right now I'm working on selling my current truck so all of these questions are for future reference,I'm hoping to get the F-350 by December and having it done by Feb. or so. I will post pictures when I get it!

 

No problem buddy, I'm looking forward to the pictures.

 

I'm not sure about the terms hydro and nitro, but I do know they gas charge shocks to prevent the oil from cavitating and turning to foam. I'm guessing hydo is a basic hydralic shock and nitro is a nitrogen charged gas shock.

 

Yep, generally a hydro shock is not gas charged, and a nitro is nitrogen charged (meaning it will constantly expand until it can't (either the weight of the vehicle or the stops limit it.)

If you are on a budget, you can always get blocks for the back now, and change them to springs later if there is too much axle wrap (i.e. hopping.)

 

But why buy something that's inferior and known to cause problems? You'd be better off spending the money for the springs now, so you only have to take apart the rear end once and only have to buy one product.
