Advice needed on regearing

So, i ordered MB TKO 17" and Duratrack 315/70-17 with 2.5" Rubicon Express Coil Lift w/shocks for 2013 JK Unlimited 3.6v with 3.27 axle.
My local shop will install all above, but they never mention on regearing and reprogramming module for fixing the speedo after putting bigger tires.
When i asked them, they said i should be okay without it.

What would you suggest? Its going to be my daily driver.

The 3.21's are a little sluggish with the 315's. you could live with it but the 4.10's make a huge difference.

There's about 20 threads on this issue. I would start there.

4.10's are perfect for most areas (I have same tires/size but stock wheels and manual transmission). Since I'm in near the mountain mountains and tow light stuff I'd go 4.56 if I was starting from where you are (and needing a re-gear).

Check the other threads to get a ton of info involving all the variables at hand
