last weekend i was wheeling at kelly flats in two wheel drive bcause i was on a camping trip and have 4.10 in the rear and 3.73 gears in the front. i wasnt having much trouble so i went for heart attack hill.it was interesting and i made it pretty far rather easily i however could not make the whole thing, and rather than have my blazer stuck on the mountian i risked using four wheel and finished the trail. alot of wheelers i talked to up there said it was ok for offroad use.I even met a guy with a ford who runs that set up buy choice. i was always thought this was the worst thing you could do resulting in transfer case explosion so is this ok for just off-road use? i plan on getting 4.10 in the front once i get the funds. id just like too know if i can still four wheel for now.
