I'm actually picking up some rubicon take offs tuesday/wednesday and was literally just now googling to see if new tires and wheels voided warranty.

I'm guessing it does since it affects the odometer...Guess that means I'm holding on to my scrawny stock X tires and putting them on before any warranty work.

 

not true. the dealership can reprogram for larger tires

 

would they charge me for this?

 

they can only go to 32's

 

if all you want is 4.10s, get some pull offs from someone on here that upgraded. I gave my 4.10s to a friend but I would have sold them for like $100- $150. They are the same dana/spicer gears that you would be buying from the dealer. Just get a set that way and take it to a shop that knows what they are doing. Don't tell the dealer that you swapped the gear ratio's and they will never know. Plus it will not effect your warranty unless something goes wrong with those gears or install or something directly related to them. If that is the case then the installer is likely at fault.

Did the dealership try to tell you something like your whole warranty would void if another shop did your gears?

 

Nah they didn't mention that, but I had assumed that's what would happen (Since it would affect the drive train). The way I saw it, if they can get out of the warranty they will try.

 

This is just one data point, but my auto transmission burned up and I took the Jeep to a dealer in town. I explained how I tow 3500#. He said I probably wouldn't be covered by warranty since I had 35" tires. I mentioned that should be offset by the 5.13 gears I had installed. He pretty much said "Oh. That's different. The transmission shouldn't have been overstressed with that setup."

Bottom line: New transmission, 100% covered under warranty.

Even though I have a Hypertech to reprogram for tires and gears, I paid the dealer to get it as close as he could. His words: "Now you have proof that the dealer knows about the gears and tires and set things up within the limits of the tools." Cool dealer, really.

I should say, cool service department since I would never actually buy a vehicle from that particular dealer. Service dept = cool. Sales-scum = bad.

 

look up the magnuson moss act. They have to prove an aftermarket part caused a specific issue. they cannot say they whole warranty is dead just because you did not have them do the gears.
