Leaf Spring replacement help

hello fellow jeepers

I need some advice on new leaf springs/lift kit installation.

so my leaf springs are pretty much shot and very flat and they need replacement asap.

so my question I need help with is...if i buy 1.5" or 2.5" leaf springs for replacement, will i need to extend my brake lines in the front and rear?

also, will i need to replace the drop pitman arm and get an extended cv driveline shaft?

any help and advice would be much appreciated.

Probably not, but the drop pitman arm may help if you go to 2.5 or higher. The brake lines depend on how much droop you get, normal street driving would be no problem but if you disconnect the sway bar and go off road your brake lines could be stretched, sometimes relocating the brake lined is enough. At the 2.5 or above you may need a TC drop or SYE depending on if you get vibration

I have 2 inch BDS springs and 1 inch shackes. It has netted me actual 4.5ish inches of lift. I have my stock brakelines still but think I am going to ise Anticanmans relocation trick because once I put proper shocks on the brakelines will not be long enough. I use a 1 inch tcase drop as well until I can afford the SYE and drive shaft. However with my current set up I still beat on her like she owes me money and she keeps coming back for more.

Depends on their condition, but you at least would want new bushings. For minimal price I would put on new shackles and hardware, probably greasable bolts as the movement of the shackles really affects how smooth you ride.

Boomarang shackles are always a good idea. If you have mil wrapped springs you will need 1 inch lift shackles to clear the mil wrap

Did you have to extend the brake lines in the front and brake hose in the rear?

Your brake lines can be relocated. Anticanman has a nice relocation write up that works well.

As for the transfer case drop, IMHO, it's as much a tire size issue as it is a lift height issue. On my last rig we had a 2.5" Rancho lift and 33's. Didn't do the TC drop at first and dropped the rear driveshaft going over a speed bump. I'm not kidding. A speed bump. Put in the TC drop, never had a problem. On our current YJ we're running a 2.5" OME lift and 1.5" body lift along with 31's. Put in the TC drop at lift time and the skid plate kept getting hung up on the trail. Pulled the drop, forklift tested the lift to see if we would get a disconnect and we're not even close. I *think* the tire size changing the angle has something to do with whether or not you need a TC drop with a 2.5" lift. With a 4" lift, I would have to assume that the TC drop is not optional (unless you go SYE and CV driveshaft).
