You ought to read and understand every word before replying. I said he didn't NEED to regear with an 8 speed. And no kidding Yukons are a brand, I suggested them and that ratio because they're a reliable brand and that ratio would be fitting for 35's.
What transmission do you have? If it's the 6 speed, you probably should regear to yukon 4.11's. If it's the 8 speeds, you don't need to regear. These guys that are telling you to don't know what they're talking about without all of the information.
