You'd have to check your gear ratio. More than likely you have 4.10's, but since the seller is selling the front and rear together and they have the same ratio you would be fine, just would have to swap both.
Sorry to hear the bad news Kyle. If I had the cash I'd be all over this deal, but it's just not in the finances right now. I would have taken the URD kit off your hands too.
Good luck to you sir.
