Which brand of coil springs will offer the best quality and the correct height?
I am looking a set for 4" of lift, and my 2dr JK is equipped with steel bumpers and winch.
Thanks!

 

If you go with TeraFlex's 3" kit you will get about a 4+" lift with your 2 door.

 

Thanks for the reply! I am currenty using RE 3.5 coil springs with Teraflex CAs, however, I am really perfer to Teraflex coils springs, becasue I will have a complete Teraflex kt if I change my RE coil springs to the Teraflex's.
By the way, what lift height will I get if I install the 4" coil springs on my 2dr JK? Thanks!

 

I have been very happy with my Black Diamond Springs.

 

People were reporting 5-6" with the 4" TF coils.
(I believe TF has released new coils that give a truer lift height, so the old measurements may no longer be correct...)

 

Thanks for the replies. However, are the Teraflex coil springs heavy duty?

 

if you're happy with te height of your RE springs and they're also comfortable to ride on, I don't see the point in changing them only to have all the same brand

 

In fact, after I installed the 37" tires, I found out that I need more tire clearance spaces.
Although I have another 1" BL, I still have little spacing issue with tires and bumpers. As long as I am using the short arm kit, I will stay around 4-4.5" of suspension lift height, so this is why I want to change my current 3.5" coil springs to a set of 4" coil springs, and maybe the 4" coil springs will give me like 4.5" lift height.

 

Depending how high you want...Why not just add 0.5 or 1" coil spacers??

 

You do realize after 3" on the two door your going to need to invest in drivelines right?

Whats size tires do you want to run? I'm very please at how my Jk drives with 3" coils and 37's, just flat fenders and longer bump stops. Its great for a DD vehicle and wheeler.

Also, if your lifting to 4" you need a very complete kit or you wont be happy with the steering or driving, track bar brackets and a drop pitman arm is basically a must.
