I agree with that. I regularly rev mine up to 3k.

 

You have a Manual, he has an Auto. There is just about zero similarity between them.

With 5.13's and 33's (appx 32" actual height), he'll be running about 2600 rpm at 70. A 6spd with 5.13's would need to be rolling on 40's (39" actual height) to run the same rpm.



There are some really neat charts in the drivetrain section of the faq's...

 

Looks like plans have changed. Might be running the 33's for a while. Anyone run that setup?

 

I had my gears installed at NR. Their are awesome BTW, but I babied my gears on the way back around the sound which was a 2 hour drive. I drove for about 20-30 min, then would stop for 5-10 to cool. So, if you are leaving the same day, it might take some time getting back to Canada.

Also, I have an Auto w/33's and 4.88's. I love my setup since I like to drive 75-80 on the highway. But, if you are ever considering going above 33's, definately get the 5.13's, or higher.

 

I'd wait till you know for sure when you're getting the 37's , unless you never plan on driving on the highway.

 

Faq's --> rpm chart !!
As well as several similar threads in just the last 2 days. You have an Auto. You'll be fine. Roughly 2600 rpm at 70 mph. Same as a bone stock 6spd rubicon driving right out of the factory doors.

The only negative will be if you tow heavy loads with OD Off. OD On, you will love it.

 

Bad info for an auto guy. You ARE shifting into 6th right???

YES!! X2

With an auto you will be MORE than fine. Before my 35's came in I ran the OEM "Rubicon" BFG MT's (23") on 5:13's and the Jeep drove like it should have from the factory. I have an auto and the autos in these rigs are waaayyyy too tall for the anemic 3.8. I described it all out a while back in the thread below.
