It is very noticeable jump in torque. I was at 3.73 stock so jumping up to 4.56 on 32s is "fun".
I plan on going up to 35s. My lift kit and 35s are sitting in the garage waiting for me to get the time and energy to get them installed.
In the meantime it's great. Taking it easy for next 500 miles to break them in. But I can feel the increase in acceleration and torque. The large hill outside my neighborhood is a huge diff in feeling. And at 60mph I can feel and hear the gears strain a bit more then normal. Imagine I will lose a gallon or two fuel economy too. But I like the feeling. When I go down hill and take foot off gas I feel the gears giving me a soft breaking effect much like down shifting would do. Almost has a 4hi feel if you know what I mean. :thumbup:
