The UCA and ball joints arrived within days of me placing the order. I was able to do the installation in about 3 hours. I did need to enlist a friend as I needed a third hand. The installation is very doable with basic automotive tools and skills. FYI the removal of the old ball joints were probably the most difficult part and has nothing to do with JBA. If I hadn't spent more time looking for that peski 10mm socket I could have done it in less time. Great communication with the company back and forth. It's only been a week since I have installed them so I really haven't gotten a chance to see how they perform off-road. I do feel the difference in the ride and a slightly difference in the look (improvement).
