Are 4.88 gears on 2013 manual too much?

I have 35" tires and currently have the 3.73 gears on my 2013 Unlimited with manual tranny. I daily drive her about 90 miles a day and I hate that it is so bogged down in 6th and even 5th at times. So it's time to get new gears. I have seen the chart and see that 4.56 looks to be the ideal gear. But I am concerned because I also tow my 3000 pound boat and am wondering if I should go up (down?) one more gear ratio to 4.88's to account for towing... I don't think I will ever be going to 37's just because of my commute so that is not an issue.

Any thoughts?

I would go 4:88 since towing is in its future. Pluss later if you do go 37, you are in the ball park.

my 2$ bucks worth.

I have 4:88s, albeit with an automatic, and really like the combination. I think with your wanting to tow the 4:88s will work very well.

I have 4.56's with a 6-speed. I love it...its just about perfect. If I had the auto, I would have done 4.88's. Honestly, I dont think you will be able to tell the difference between the two.

I think I will go with 4.88's then. Another question though: I know I need dana 30 for the front and 44 for the rear but I also see the term reverse jk in some of the gear descriptions. Do I need reverse gears or just regular ones?
