I have a 14 1500 and I'm looking to do a 6" lift. I'm also looking to change out my front diff to an OEM 3.92 ratio along w the regear of the rear. My question is, what can I use to recal the speedo? Is there anything that needs to be recalibrated in the trucks ecu in regards to transmission shifting? Is there anything else I need to know before I do these upgrades? Any info would be greatly helpful being im new to the ram 1500 fam. Thank you!

You will need to get a Dablio in tune /Trinity to recal the speedo or other tunner that can recall the tire size for you. I would also look into a custom tune so you can gain back some power that will be lost with the bigger tires.

Good luck,

Going from 3.21 w OEM 33" tires to 3.92 w 35s, you still there will be much loss if it's not tuned?

The 3.92 will definitely help, if I was lifting a RAM and putting on 35" tires on I would want a tune to help get the truck moving again.
