Rookie question....

I currently have this 3inch lift kit on my 2019 sr5. I would like to some how lift it an inch more to clear 33s. (I would like to avoid the mount chop, but will do if last option.) is adding a 1 inch spacer lift an option?

 

Just get adjustable UCAs like SPC. You can clear 33s easy with no CMC with only about 2” of total lift.
The only thing you will have to trim is a small amount of plastic in the front of your tires

 

A coilover based lift will not help you run larger tires. The suspension still needs to move through the same range of motion. Things that help you clear larger tires include alignment that moves the wheel forward and trimming of the frame and wheel well. That said, many people report being able to fit 255/85r16 (33”) with no modifications.

BTW: the OME 3rd gen kit is a 2” lift. If you lifted your 3rd gen 3” you would have 0” of down travel (aka droop).
