I personally wouldn't listen to anything anyone that works at 4wheelparts says. Honestly the only thing 99% of the people that work there are capeable of doing is going on their computer, and looking up what they can sell you for your truck, then trying to sell it to you. They will never recommend anything they don't sell, even if it would better suite your needs which shows me that they absolutely do not look out for their customer's best intrest they're only there to try to sell you anything and everything they can. As a matter of fact, they just tried to sell Etalian steering stabilizers for his truck, and you don't even them on our truck's because of the rack and pinion steereing, they're for straight axle trucks. Depending on the width,backspacing, and offset of your rims you can put a 35x12.50 or a 33x12.50 (or they're metric equivelent). The 35s will require the pinch weld mod, which may sound scary but it's really no big deal at all. (do a search for it)
