Approximately how long does it take to swap both arms with air tools and decent wrenching skills?
For anyone else looking for help or guidance with this, it was very easy and took 15-20 minutes.

Chocolate Thunder, thanks for posting your experience. Would you mind posting the steps you took to install them? Did you have to do anything special to support the Jeep while you did it to get them in? Thanks

throw a jack on the pinion, zip off the 4 LCA bolts, lower pinion while watching an angle finder to get desired numbers, stop jack, adjust new LCAs, zip em back on.

I installed the slightly longer Mopar arms that aren’t adjustable so it was a little easier. I did one side at a time. Remove the 15mm nut that attaches the bracket to the arm. Use a 21mm socket and 24mm wrench (or crescent wrench if you don’t have a wrench that big) to remove the nut/bolt on the frame (upper) end. I used an impact gun on the 21mm side to make quick work of it. Do the same at the axle (lower) end. Remove the arm and install the new one in its place. I installed the axle end first then frame end. Since they’re only slightly longer I didn’t have to use a jack or work hard to get the holes to line up. Just shook and rocked the body of the Jeep and jiggled the bolt in when they lined up. I had a big screwdriver to use as a pry tool but I didn’t need it. Torque the bolts to 190 ft/lbs. Put the nuts back on to attach the brackets. Be careful not to overtighten it. I don’t know the torque spec, I tightened it till snug plus a tiny bit.

Torque the bolts to 103 ft/lbs + another 50 degrees (Really, Jeep? I just torqued then to 120 abd called it s day). Put the nuts back on to attach the brackets. Be careful not to overtighten it. I don’t know the torque spec, I tightened it till snug plus a tiny bit.
According to the Mopar lift kit install instructions, 190ftlbs on the LCA bolts

Thanks. I didn’t have access to those instructions, I went by the torque specs posted by @JAY in the sticky thread in the DIY forum. 190 ft/lbs is “as tight as you can get it” in my garage. Lol.

If you look up the lift kit on quadratec website, they have a PDF for it. Should be the last page in the document.

I haven’t taken it in to have alignment and caster checked but I drove a lot today and took her through some mud holes and dunes at the beach. It feels good with the longer Mopar LCAs.

OK, install sounds simple enough for the Mopar version. I'm probably overthinking it as I usually do!

So best deal I'm finding is $60 plus $10 shipping plus sales tax anybody finding a better deal?

I just swapped out my Mopar arms for adjustable Teraflex Alpine arms to get some caster back, and it seems to have made my jeep wander worse than before. I set them at 24 5/8. ( looks close to 1/2 inch longer than the Mopars side by side) I also notice a lot more feedback through the steering wheel now over bumps.

The additional feedback is probably from the stiffer bushing which I believe are polyurethane but could be wrong. Mopar arms are still using a stock type rubber bushing that would absorb some of that harshness.
