Review on Yukon Gear TV6 456 29 Performance Differential by Jason Cartwright

So the part itself is great. Installed on 4Runner with a friend, no problems. Judging by my calls and emails to the support team, the seller of the gears I bought has no idea what they are selling. The gears had a different number and size of gears than the original parts I removed, so I wanted to make sure they were correct before doing all the work to set them up. I ended up calling Randy's Ring and Pinion (they sell the Yukon brand) to check out the app. They said there is "virtually no difference" between 4.1:1 and 4.11:1, which is the main problem. If you were wondering now, now you know it too!
