Im thinking about getting TF 2.5 BB with a 1inch M.o.r.e body lift. I will be getting 35x12.5s and was wondering if i need new gears or if this setup would work...?

 

also I have an automatic.

 

I just put 35's on my JK with auto. So far it seems to be OK. I live on a small hill and it did not shift out of overdrive. I suspect in real hiily country I will have to lock the overdrive out.I have locked it out and the RPM's came down to a better range when traveling at 70MPH. I had 33" tires prior and on big hills the overdrive had to be locked out as well. When it was the RPM's were just below 2900 RPM's at 70 MPH.The 35's make it quieter with the less RPM's in the cab. I also have the AEM cold air and that makes more noise when the motor revs up.With the stock setup it was very quiet , but now I have air intake noise but also a little more power.I will inform you if after I drive it more in differant terrain and things change. I will say the increased clearance is nice off road, I have a small steep climb that I was getting hung up on when topping the hill. It now goes right over and that is what I was after.
