rpm w/373's
Im getting ready to change the gears on my truck, its and 04 5.3, it came with the 3.42's, but it is very slow from a dig, i want to go with some 3.73's or 3.90, can some one tell me what will my rpms be more or less with the 3.73's and with the 3.90, right now i have original tires 255 70 16 (american generals), also what brand of gears, dont want something noisy, have heard good comments on Motive gears, what you all running and recommend.
Thanks in advance.
