I’ve had the RC level on my Lt TB for probably about 10k km now. Lots of off road down logging style roads and a bit of fun in the mud.
zero issues; zero issues at all, the dealer whom installed it said it was a better kit then the one they sell for TB/AT4s. So now they recommend and sell the RC kit, who Cj also doesn’t void warranty because it’s under 2”.
I love it, I would recommend it, my 2 friends who have trail bosses as well both installed it with zero issues, angles are fine on both CV and Balljoint. I’ll get the Cognito UCAs is when my ballpoints go but for now I wouldn’t worry about spending the cash on them, no point. I love the kit, survived a nice Canadian winter and again no issues
