I recently got a 2018 silverado and it came with aftermarket control arms so i dont know if i should get kruca12 or kruca13?

Great question. You will need to measure the stud on your current ball joint. If it is a 14mm stud then you will need the KRUCA13, if its a 12mm stud then you will need a KRUCA12.

Does this upgrade require to cut out the control arm bump stop? As shown in the details about this upgrade oem wheel will not fit, if running a wheel spacer make this fitment compatible?

Hi Jesus, this does not require any cutting of the bump stop. If you run a wheel spacer to achieve an effective backspacing of 4.5” or less then these will fit. The inside of the wheel will contact the front end of the control arm when turning.
