For the 20 inch rims I am just really not sure. The truck can turn ok alittle but if you turn hard the wheel it sounds like the front end is falling of the truck. And the rancho stablizer took care of some of the loose steering feel. It still has a quarter inch play side to side in the steering wheel. And the truck goes aginst the grade and wants to go acroos the center line. It is know a safety issue driving it.
