So we just bought my wife a 2016 Tahoe and I had every intention of putting the RC 3.5” lift on it. Was going to order but noticed in the instructions that the kit won’t work with aluminum knuckles!!! Started looking at the Fabtech 4” but then in the instructions it says to drill out the upper ball joint with a 1/2” drill bit. So if I have to do that with the Fabtech, could I do that with the RC? RC tech support just said “ball joints won’t fit” so I didn’t know if drilling them out would work.
