I am planning on a mild 2.5-3 inch lift for my dd. I might take it on trails now and then but nothing serious. I was ganna do 2 inch spacers and 3 inch lift shocks up front and 2 inch add a leaf, 1 inch shackles and 3 inch lift shocks in the back. would I run into any brake. Line problems or anything I should be worried about? The tires im using will be 30x9.5xR15s.

 

Relocate the front hard line brackets and get a new line for the rear.

 

I have a 2" BB on my 99 DD. comprised of spacers up front, shackles out back and 2" longer skyjacker shocks all around. Oh and new OEM leafs cause the old ones were shot..
Only issues were with install- frozen bolts and the like, but nothing mechanical that needed attention. I did get rid of sway bars and made front disco. When at full flex on 235/75's I do rub the fronts on the upper spring perch's. So make sure bump stops are longer by as much lift as you add (generally..) or softballs in the coils, apparently.. Never seen it, but I bet it works...? maybe a touch of cut and fold trimming?
