Wheel and tire fitment: this kit will fit with 17" or larger wheels with at least 4.5" of backspace and can fit up to 35x12.50" tires.
Driveshaft Fitment: Super Dutys with a two-piece driveshaft may require one of Zone's carrier bearing drop brackets. Please select your carrier bearing option from the drop-down menu above.
