I haven't as there isn't a rear bar for these trucks. I have a half ton capacity rated Gen 1 and all of the suspension stuff is lower rated (upper control arm pivots, stabiliser bar and tail shaft...) I found that Gen 2 stabilisers are thicker (and are the same spec as Gen 1 one ton rated) so I swapped it up (+ mine was actually bent anyway on one end along with a radius rod ) It appears that early Ford F150 aftermarket rear stabiliser mounting kits will work on our trucks and that will really help with turn in response and keep the rear end from twisting around.
