2012 Rubi build...37's with 5.13 or 5.38 gears??
Hey guys, just picked up a new 2012 rubi...love it! :rock:
Planning out my build and I think I am going with a 4" TeraFlex (not sure if LA or SA yet...) and 37's... Stock Dana 44's front and back with 4.10 gears...should I go with 5.13 or 5.38 gears?? The 3.6 engine is awesome so far...I live in Colorado and it will be a DD and a trail beast. Will 5.38 be too much? I have an auto tranny... Thanks in advance... |
I have a 12 rubi with 4.10 auto and 35s. I would not change gears. Plenty of power and get around 18 mpg on my daily commute. I am going to 37 soon and have no plans to regear
|
What kind of elevations do you go through? Living in Denver and heading up to the trails in the mountains is a hike...5,000 feet to 11,000+ feet...I am worried about those long runs uphill with 4.10's

I think with the pentastar we have to set some of the past gearing suggestions aside. I also wonder if either of the options you're suggesting are too much. What about 4.56s?

Any Colorado guys out there have the pentastar and did some gear changes? |
Unless you want to climb the hills in OD, 5.13s & 5.38s are too much for 37s. I too have 35s and 4.10s and still find myself with the ECO light on all the time. I'd look at 4.56 or 4.88s.

Running 37's with 5:38's in mine. Makes it nice on climbing up hills, lots of bottom end. However not the best for mpg's, I'd consider 4:88's -5:13's. However there is no way I would ever change mine down.

I'm in Colorado with 37s an went with 4.88. It feels pretty much the same as stock. Cruises E470 at 80-85 and gets up the mountains well. I don't have any complaints with the setup. I'd agree that the pre2012 recommendations don't apply to the 12s.

4 1/2 AEV. So far I'm loving it.
