The 4.10 is in! I've been driving it to work for a couple of weeks, and I love the new gear ratio. The 216 is happy anywhere between 50 - 55 in top gear, nowhere near top cruising speed. Power is adequate, fuel economy improved. Tires 235/85R16. Feels very relaxed compared to what it did. On the weekend I had a 170-mile day. No problem. My truck is 7-800 pounds heavier than a 1/2-ton.
