4 in. suspension lift, 2 inch BL?

Hello all, I have a 97 tj 4.0 with a skyjacker 2 in. body lift kit that came on it with skyjacker 7000 shocks. I want to upgrade to a 4 inch suspension lift along with the 2 in. body lift, so what all do I need? I was hoping I could go ahead and use the shocks that I already have on there since they are brand new pretty much and just purchase the Springs needed for the lift instead of buying a full kit, is this possible? Thanks for your help, sorry if my question is worded weird, i'm in a hurry...

BL has not impact on adding a spring lift. Suspension lift, you have to get new shocks. Most "kits" come with shocks

I would get rid of the 2 inch body lift for beginners. You will need new shocks with the 4 inch suspension lift if you want to do it correctly.

If you're going to do a body lift, i would only put on a 1" lift...

anything above that is asking for trouble

Look around on the forums anything over a one inch body lift is frowned upon they dont look good, and they arent that safe, id put a one inch body lift on (or put it back to stock) if you put a 4 inch suspension, and yes you would definitely need new shocks.

I have coil spacers not a body lift my bad lol, dude that sold it to me said it had a body lift but after researching a bit it has coil spacers, and no body lift... so rephrasing the question how does everyone feel about a 4 inch suspension lift with 2 inch coil spacers?

Sorry to ask so many questions, so with the 4 inch suspension lift and 2 inch coil spacers, Will I need to extend the drive shaft and brake lines?

The 3-4" mark is the point where longer front lines are needed (not sure about the rears). If you go over 4 on suspension longer (and adjustable) control arms become a necessity.

Also keep in mind that when going with that much of a suspension lift you will need a SYE kit and new rear drive shaft. Which is another $450 roughly. The front stock drive shaft has a slide on it that will cover the minimal extension you have.

What size tires are you wanting to run with? Reason I ask is unless you want to run larger than 35" tires you will be fine with a 4" suspension and 1" body lift.

And then you get into yet another predicament - 35" tires are not the safest to run on a stock rear axle IF it's the Dana 35 (it will have a rubber plug instead of a bolt). Shafts are prone to snapping with that much beef hanging off the sides!

That is all that comes to mind at the moment...

ya I have a Dana 35 so i'm just gonna do 33's so should I just do away with the 2 inch spacers that are already installed on and do just the 4 inch suspension lift? And with a 4 inch suspension lift I do need a new drive shaft, and extended brake lines correct?

Brake lines, **SYE KIT** and drive shaft (Search Tom Woods drive shaft and Advance Adapters SYE - there are kits available) And yeah, the spacer I would not run, IMO. 4" is enough suspenion for 33's.

However, a very few people get away with 4 inches without doing the SYE and drive shaft swap. May be something to just install and try it first and see if you have vibrations or not.
