My old boss had the trail gear 6.5:1 gears in his sami. He drove his sami all over the place, he would dive it down to L.A. and we live far nor cal.
I'm going to buy them pretty soon here, why not?! half as much as any other set of 6.5 gears and its got a life time warranty on it. They way i see it...ya got nothing to loose.
