In a 3.4 5-speed (although I'll take input from auto folks too). I'm not looking to do this permanently, but perhaps for a couple years until my 33's wear out. Ultimately I plan on running 35" tires, but my 33's are near new and I'm too cheap not to use them.
I considered 4.88 gears as it would be a happy medium between the two tire sizes. But I'm afraid after running 4.88 with 33's and getting used to it, it will make the truck feel sluggish with 35's. If I were going straight to 35's, there is no question I would run the 5.29 - I prefer lower gearing as I do a lot of mountain driving and live at high altitude, not to mention the better crawl ratio.
According to the gear ratio calculator 5.29 and 33's would turn 3400 rpm at 75mph compared to 2800 with the stock setup. Pretty high, but not nuts.
Does anyone here have personal experience with this combination?
