I like the 4.10's I pulled my 3.42's out and Pyle Differential in Baytown installed the new one's . They said I'd be happier with the 4.10's over the 3.73's with the overdrive tranny and boy were they right. I drive 80 miles round trip 6 to 7 days a week and never had a problem out of them. They dared me to try and tear them up at the track and I haven't so far. They did recommend putting factory gears back in since the Richmond have a tendency to make noise and I did. If I could just talk myself into getting a Gear Vendors unit I would be in heaven on the highway! BTW, opinions are like assholes, we all have one! LOL
