I have cross over steering and no sway bar on the front and it does ok to the point I need to trim the fenders. The rear is terrible due to the spring arch and minimal shock travel. I run 35's and want to stay with that. I have no welding skills but could take it to a guy I have seen guys going with full size chevy leaf set ups but I don't know what all is entailed in fitting them to the 4runner.
