The upgrade is simple. Two jack stands and a rolling floor jack. It is better to have the springs and spacers and replace both at one time. You can also search youtube for some good information. It took about 1 hr for one person to get this done. My five year old was the supervisor for this job. You can also search Budget Boost and spring change install on the forum. I am sure that someone has posted this before. One important note. Since you are lifting and going to a bigger tire make sure that you get a front end alignment done soon after the upgrade.
1) Lift the front of the Jeep and place it on the jack stands. Get it as high as you can.
2) Remove, tires, then place floor jack under the axle, then remove the bottom bolts for your shocks and the lower bolts from the disconnects.
3) Lower the axle (one side at a time). The old springs and factory spacers should just slide out.
4). If I remember correctly I used the factory spacer in the front and placed it on top of the new spacer. Put this on top of the new spring and set in place.
5) Raise jack and replace bolts in disconnects and shocks. I did not place the bump stops as directed because I do not do that much extreme off-roading.
6) repeat steps for the other side.
The rear is similar but you can remove both tires at the same time.
1) Raise Jeep and place on jack stands and remove rear tires.
2) Remove lower bolt from shocks and the lower bolt on the sway bar. (jack under differential)
3) lower the jack.
4) I had to push down on the axle to remove the old springs.
5) Place new spacer on top of the new springs. (DO NOT use old factory spacer in conjunction with new spacer)
6) Raise jack and replace bolts for shocks and sway bar.
7) Replace tires.
***Once all 4 tires are back on the ground torque the shocks, rear sway bar and disconnects. Performing this step must be done after the weight is on the tires. You can do a search on the torque settings. I cannot remember them at this time.
