That's a no-brainer... with 35" tires the only significant increase in power will come from re-gearing your axles.

i know i need it regeared but i can afford that at the moment its like a grand to have it regeared what gears should i go with??

4:56 will bring you on the econo side of gas millage
4:88 will to you to other side but give you more torque.
