I initially put a RC 3" lift kit on our Rubi. After a couple of years it was basically shot. Replaced with a Terra Flex lift kit with Bilstein shocks and it made a world of difference. Never looking at RC again.
When I bought my Rancho lift in '14 for my F150, Rough Country had a horrible reputation. I've heard the last few years they have really worked to improve their products.
Question for the dude above, what else is there for lifts? Literally every lift is a diff drop, that's how you compensate for the increase in lift so the CV angle isn't terrible. Even if you do a knuckle lift you still need a diff drop.
