So the lift wasnt that bad. Do yourself a favor and spend 25$ and get a set of reverse torx sockets from Amazon and a 18mm ratcheting box head wrench. You'll be glad you did.
It helps to have another person for a couple things.... but you could probably do it solo with another jack.
I lost 3 hours because of bad parts. RRO has a recall on the front sway bar arms. I didn't know this and had to cut and weld mine shorter. That means install, reinstall tires, identify problem, take off tires, remove and modify li ks, reinstall, remount tires, and then test drive. This sucked.
If there wasnt this problem the total I stall would have been about 4.5 hours. I would not recommend RRO as a result of this.
There is a good video here:
It's the teraflex lift. Pretty much same.
Also, if you have a trailhawk, you will need a wheel grinder to trim some off the rear skid plate as the RRO kit doesnt have the skid lowering blocks.
Honestly, if you got a different kit, assuming they are better, it isn't a bad install.
