so, if you had to do it again... or you could do a free gear swap when you get your 37's one day.. would you still for sure stay with 5:13's and not go up to the 5:38's.
I have just bought 37x12.50 17s and will run it with a 4.5 inch mopar lift (RE) I can't decide whether to just go to a 5:38 or the 5:13s. I live on an island... speed limit doesn't exceed 45. I will take it on the mainland and highway... but pretty much only for warranty work, and oil changes. Not much highway driving planned at all.

Would you really notice the gear change on a 6 speed? I would think just moving all your shft points down a gear would be the same thing. Now I agree, it would make a difference if you use or need to use 6th. I thinka gear that is that tall and this low of power would be useless but first gear was just as useless on the road before my 35s.
With my 35s I just noticed first gear is more useable, the rest I just seem to stay in the next lower gear than before and nothing else has changed. I agree, the highway I need to stay in 5th unless down hill or very flat. Up hill I will stay in 5th or even 4th.
All changing my gears would do is move all my gearing back down and now I would need 6th again but would not feel any different than 5th does now at highway speeds.
Thoughts.?

sounds like 5:13's wil be just fine with 37's... I agree with this thread that first gear with stock 32's is almost useless... so if 4lo.com says that 5:13's with 37's will be an improvement over stock... then coooooool!!!!!

All the info you need for your tranny and transfer case etc.. can be found here:

As you will see, there is a definite difference in the transmissions and transfer cases.
