I have the teraflex 3" lift with upgraded beefier arms, but I am disappointed with the rake and I am about to throw on my shrockwork sliders (they arrived yesterday and yes, they are bombproof ). Here is my dilema - i got the sliders with no bodylift, what parts are nessesary to upgrade the 3" to the 4" lift? Is it just springs and shocks? Please help i am feeling for my JK and dont want to dump a ton of cash.

 

springs shocks control arms track bar sometimes a front and rear driveshaft

 

just throw in some spacers in the front and you should be good

 

x2. Or if you'd rather, you can go w/ taller springs. The TF arms seem to be plenty long enough. At least mine do.
