My father and I installed these today and I wanted to share some things I learned. For starters, I went back and forth on what to buy, watched a million videos, and studied tons of different kits. The local shop wanted 300-400 to install these which included a front end alignment (more on that later). They also wanted 850 to install a Rough County 2.5” lift which included shocks and springs. I didn’t want to compromise my ride quality as my Jeep is quiet and smooth, I also prefer to do my own work so this is the kit I chose. For starters, these are exactly 2.5” hard poly pucks, very durable. You do not need ANY additional parts to install this, no shocks, no coils, no extra long sway bar links, no nothing. There is already half inch spacers installed from the factory on the front and back of your Jeep, you can leave those in and install these for a max of 2.5” lift, or if you want to level your Jeep then remove the rear spacer and reinstall the front one with the new puck. This will yield 2.5” in the front and 2” in the rear, and in my case raised my Jeep exactly 38.5” from center tire ground up to fender front and back. As for puck and spacer placement, I removed the spacer and installed the puck then put the factory spacer back on, followed by the coil. It seemed much more stable this way. Install only took around 4 hours with help...jacked it up as high as possible in the middle, placed two jack stands on both sides but kept the axle supported. I removed the sway bar links, loosened the brake lines, removed the drive shaft because it’s an automatic, took out the bottom shock bolts, then we lowered the axle as far as it would go, this allowed us to remove the coils with no problem and put the pucks in the front then replaced the factory spacers on the front. We then twisted the coils back on until they hit a metal stop, then jacked up the axle and started putting everything back together in reverse order. We used open ended wrenches and an impact drill with impact bits. We did use loctite on the driveshaft bolts when reinstalling. I also put 1.5” wheel spacers when reinstalling the tires to give it a little more clearance for larger tires and a more aggressive stance. The front took around 2-3 hours total and the rear was much easier, took around 30 minutes or so. Jacked up the rear in the middle differential, took the tires off, removed the bottom sway bar bolts, bottom shock bolts, loosened the brake and ABS lines, dropped the axle, removed the coils, tossed the factory 1/2” spacer, placed the pucks in and replaced everything in reverse order. We did rent a coil compressor but we didn’t need it, if you get the axle low enough in the front and back it’s not needed in the least. I will be getting a front end alignment as we did mess with control arms and sway bars, it seems to be the recommended thing to do. Some also report that the steering wheel needs straightened afterwards which ours did not, just be sure to make the wheels straight when starting..if so it’s an easy fix that only takes a few minutes, just Google it. The pics I included only show the front pucks installed so you can see the visual difference from front to back. Notice the space difference in the front wheel to fender. As for drive quality after install it feels exactly the same, I plan on adding larger tires soon to net a total of 5” of lift. I’m glad I went this route, my wife and kids can still get in with a little jump and I saved nearly 750 bucks.
