^^^X2 on the 4.10's!!!!!!!!Average price is usually around $2000 but dealers tend to be on the high side. There are multiple threads on this subject check them out since it does depend on geography. If you decide to go with the dealer find out how many gear changes they have in the last year and you might consider going with 4.10s. You never know when you may want bigger tires or to tow a trailer. It's expensive so you might as well get it right the first time.
Who is this directed towards? Op was quoted $2900?Maybe they laughed because they've never swapped from 3.21s to 3.73s....because it makes no sense. Why spend $1000 for minimal gain? 3.73s are worth it as a factory upgrade because it's the best you can get without spending $5k more for a Rubi with 4.10s. And still under factory warranty. What are you hoping to get out of the swap? MPG? Towing? Have you driven both back to back?
Going from 3.21 to 3.73 is not worth all that money, the gain is gonna be hardly noticeable. Just like it was mentioned before might wanna consider 4.10, specially if you want bigger tires. The mpg is still gonna be good and IMO it should make you happier. Price wise $2900 is a bit too high. I'm in NY and it cost me $1400 (parts and labor) going from 3.21 to 4.88.Hey jeepherz I am trying to get more power Before I went two inches bigger on the tires, I got good acceleration in the lower gears but poor at highway speeds The online great ratio chart indicates that the 3.73 will give me higher rpms With the bigger tires than I had with the 3.21 So I'm thinking the 3.73 should be good since this is my daily driver
