have a dodge 1500 with the 3/4 ton axles, lifting the truck about 13 or 14 inches and putting 39" tires on was wondering what gears i should run in this thing

That depends on what you are going to use it for with a 39 in tire 4.27 to 4.56 better economy and highway usage, 4.88, 5.13, 5.29 and 5.38 will give you the closest to factory gear ratio. But 5.71 or 6.17 will give you the best off road capabilities. I hope this helps. Good luck and have fun.
