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.
