Keep in mind if you do the slot delete you will need adjustable upper control arms to do an alignment. Also, i believe only SVC and Icon let you adjust them while on the truck. The others require you to remove the bolts to turn the heims. Also, make sure you have a shop that understands how to do an alignment using the UCAs. I’d suggest the SPC cam kit and then weld some plates on the bottom side of the frame to “box out” where the LCA attaches. Adding gauge (doubler) to the vertical flange will help but the better option is creating a stronger cross section. Keep it dirty did the same thing and i copied it and did the same to mine
