These do exactly what you expect them to. Night-and-day difference from stock arms on a lifted jeep in both handling and correcting the pinion angles. They also weigh about 2x what the stock arms do, very beefy. Follow the below steps, and they are rather simple to install (done on a 2017 JKU).
1. Call Rough Country for measurements needed, it takes only a couple mins. Write them down. Don't use the generic measurements in the instructions, you need specific measurements for your jeep and lift height for best results.
2. Jackstand the front from the frame, place jack under axle and lift it up JUST a hair to take tension off the shock bolts
3. Disconnect sway bar links, remove bolt connecting track bar to the frame, remove lower shock bolts
4. Loosen ALL Control Arm bolts until you can spin the nut by hand (lower and upper), but do NOT remove. If you do, you will make your life much harder
5. Remove both lower control arms. Measure one from hole to hole, then apply that to the measurement RC gave you for the new arms. Build the new lower arms to length. Dont forget to tighten the grease points, they come shipped loose.
6. Install lower arms (frame first, then axle for all arms). You will need to push the axle some, maybe mess with the jack to line holes up. I was able to just push with my shoulder enough with little effort. Do not torque down bolts yet. Be sure to put the right one in for its side - pay attention to the direction of the bend compared to stock.
7. Repeat for upper control arms. I found in my 2017 JKU i did not need to cut the passenger bolt (the frame has a passthru) but on other years of JK it was needed. If you cannot align the holes with pushing alone, try jacking under the diff behind the axle to rotate the axle.
8. Once all arms are in, replace the lower shock bolts/track bar/sway links in that order. Once all are in, torque everything down. Be sure to pay attention to torque specs.
9. Reinstall tires, repeat for rear in the same order.
Stick to this order strictly, and this isn't a bad job at all. Deviate, and you'll find yourself swearing and sweating very quickly. Also, dont forget to test steering afterwards, most likely your steering wheel will need recentered slightly.
