I just lifted my 05 silverado LS and put 35's on it. I have already noticed it does not have as much zip as it did before the lift and feel like I should be thinking about changing the gear ratio on it. What should I go with? I was thinking 4.10's but I didnt know if that would be a huge difference from 3.73's and I dont wanna make it undriveable on the expressway... any advice???
