I have a 2008 JKU Rubicon auto with a 3 inch BDS lift. I've gone offroading twice and the last time I hit the front drive shaft on the trans pan so I'm in the market for a smaller diameter front drive shaft.

I just finished putting 35s on my Rubicon. I live in Chicago and don't wheel often but just came back from a Colorado trip where we wheeled pretty hard. I think I hit both types of driving. I am running the TF leveling kit (spacers) with an extra 3/4" in front. I installed the Spidertrax 1.5" spacers. Here are my observations:
The 35s made it really slower. I have 4.10s as it's a 2008 Rubicon but it's much more noticeable than I thought it would be. Driving around town which is most of my driving is really slow. On the highway, 70 mph is about all it will do comfortably unless it's totally flat. I just did 3,000 miles back and forth to Colorado and it took forever and was really annoying. I got passed by "wide load" trucks in the windy sections. Not sure how much it costs to re-gear but I will strongly consider it.
The mods I have are below. Hope that is helpful for somebody.

Very informative thread! Thanks for posting up as I was thinking of buying tires and wheels really soon. Not to hijack or anything, but I just noticed people weren't really talking about their top end speed when regearing to 5.13s. I also have the stock 3.73 gears w/ an auto tranny. When you guys regeared to a higher ratio, did you lose top end speed? I hit a variety of traffic from stop and go to highway speeds off 65 mph+.

I have a 2009 2 DR, 6 spd man. X package. Stock rubi wheels and tires the day I left the lot. I get 15 MPG if I'm lucky. I don't drive like a maniac (I'm not a kid or pissed at the world). I drive city and highway. My Jeep is my DD. My head spins when thinking about this stuff. I hear sooooooo many things.. makes me wanna stay stock. OY!

I'm right there with you, SUNPRO. I've heard the same things and cannot believe some of the mpg that these modded rigs have. I bounce back between 15.8 and 17.0 on my stock JKU. When I had my 2 dr Rubicon with a Gobi roof rack, ace rock rails, rugged ridge front bumper, and a warn m8000 winch, I got 15.8 mpg at the best.. all on the stock rubi MTs and wheels.

So since my last post here is the list I've done to get ready for 35"s. keep in mind I'm building for 37"s so that I won't have issues with the 35"s for sure and if I ever decide to go to 37"s, I'm ready.
New front drive shaft
EVO Sleeves, gussets, outer axle seals
W U R X rear bumper with carrier.
Eventually I'll do a rear drive shaft but I'll wait a bit. Now just to get the tires!

So Help me out here. My 2012 just recently got hit. My buddy owns the body shop and while it was apart we installed a 2.5 RK spring/shock kit. I bought 35" MT baja's and black rock 17" rims with what I believe the proper offset. My gearing is 3.21 (my first jeep who knew).
I dont need spacers from what I've read but what will I need to do to make it okay? Not a wheeler, just like a high jeep. I do like snow but it won't go off road.
It's an automatic. Ty
