Ordered the 4" lift RockJock springs a week or so ago. They hit the door step last Friday.

RockJock and the Currie's are great to work with. Called and spoke with Brandon Currie and told him what I wanted and he recommended a spring kit.

Started the install yesterday, got one front spring installed.

Started at 6:30 this morning and got the other front side installed

Came to the house, ate breakfast and started on the rear about 9am.

Finished them around 10:15 10:30ish.

All total 3.5 to 4 hours install time with jack stands and floor jack.

Pleased with the time as this is my first TJ spring install.

Not sure if you meant to post TJ stuff in the JK forum, but that axle looks like it's gonna need to be pushed out a touch... did you center your bumpstops before installing springs??

Those 2 pics were at full droop with shocks and swaybar unhooked.

Yes i centered them and double checked once everything was hooked back up.

Yeah fair point - I saw the shocks connected and didn't realize you fully drooped it out. Those Currie springs must be quite springy to not unseat at full droop like that...

Shocks were just sitting where they belong.

Currie springs are supposed to have the most free travel.

I had to compress them to install both fronts, even at full droop.

The rears i popped them in with a little compression.

You shocks must be pretty long too... I was running the Rancho's on my TJ/LJ and it was impossible to get the springs in or out with the shocks attached. Even with the shocks detached, I also had to use a spring compressor to get the RK front springs in place.

Sorry I wasn't clear the shocks were unhooked and just hanging.

Mo way I could have gotten the front or rear installed without unbolting them
