With 3:73 gears and 35" tires, I would start a fund now to pay for the automatic transmission work you will soon need. Don't miss count the extra weight of the larger tires, it slows down acceleration and works the brakes much harder when it's time to stop. The 48 is already taxed enough as it is in stock configuration, the added weight of the tires, along with the reduced final gear the larger tires bring, spell certain sudden death syndrome for your trany. Don't look surprised when it happens, cause I'm telling you now to start saving for the repairs. Why can't people that want to run bigger tires have enough sense to get a truck with the tallest gears available?? They end up with a nice looking truck that can not get out of it's own Shadow. Ricer Bait!
