Stock JK gearing 3:21 vs 3:73 max tow option
I am sure this has been discussed but I am not really up on my gears. I ordered my Jeep yesterday and I only have a few days to change my mind on any options. So I could use some constructive feed back from people with 3:21 and 3:73 gears.
1. My 2013 JK 2 door has 3:21 and gets 20MPG average. Tows what 1200 or 1500 LB.
2. The dealer said the 3:21 and the 3:73 in the JKU gets the same millage. Hows can this be?
Programming in the trans?
No extra coolers or anything else added. I have a trailer hitch already but it comes as part of the package. So I am only really getting gears for $660 from the factory.
I rented a JKU for 2 weeks and got 20 average but I am sure it had 3:21 being a rental.
3. The dealer said the front gears are 3:21even with a 3:73 rear end. I thought you had to have matching gears front and back.
4. I don't tow much but want the ability to pull a 5500 lb boat 1/4 mile from the ramp one or twice a year for service. I know the max tow is rated for 3500 but i don't think a 1/4 mile will hurt it one or twice a year.
5 Can I pull the boat with a 3:21 rear?
Anyone have actual real world mpg numbers on the 3:21 and 3:73 stock Jeeps?
Please don't tell me to search. I did and I am still confused. Its a 660$ option so I want to be sure if I need it fine. If not Ill kill it.
I want good MPG as this is a street daily driver for me. Maybe some day more than that but downsizing to 1 car for a while. I drive 60+ miles a day so mpg is important to me. And Yes I know its a brick with an engine but I happy with my 20 to 21 on the 2 door now.
Thank oyu all in advance for your help on this.
