Re gearing a Jeep (who is the go to shop for swapping gearing in axles)?

FWIW, my wife is really disappointed I sold that thing. [Dunno] It was always in the shop. EVERY time they had to reprogram it, they had to do it 2-3x, and we'd have to keep bringing it back. It would die on her, and I'd have to drive to go fetch her. That I blame as much on the dealer as the vehicle itself. It finally just threw its last code on me after she took it for the 50k tuneup (that it didn't need) and it went from running great to misfiring constantly.


Edit: The BEST thing I can say about it is it truly held value. Purchased new in 2009 for 28? 29? something. Sold this summer for $25 at a dealer trade-in, although it was immaculately clean. So we lost $1000 / year? (plus many hours in the shop….). That's almost like driving it for free.

Yep, neoprene is unsprung weight, right? Each seat cover probably adds at least 500lbs of real weight to that beast. I agree, you were lucky to pull 80mph with the covers on.
Now if you had Molle-compatible Mall Ninja covers like I have, you'd be totally high-speed, low-drag like me. LOL.

take it in for a real live tuning on a dyno, a good dyno tuner can make a world of difference... there are several shops here in Denver metro that do live tuning.

But I-70 up/down the mountains is a huge pain, as it chokes near Vail pass / Eisenhower every time. I'm planning on 4.88 but am worried about highway use as I still drive it 80mph on the 470 quite a bit.

There's a guy in parker who is supposed to be cheap. But I've heard Crawlertech for a good (and expensive) job.

I've thought about trying a cold air intake first, since it would be a much cheaper upgrade. Just need a little bit more cool air to make it up and over the mountain.

Guys name is josh, does a shit ton of re-gears. Good guy, good prices. He re geared my tj to 4.88 and it made a world of difference with 35" blue label bfg krawlers. If you're interested shoot me a pm and I'll find his contact info.

Josh is good to go, I can't recall what I bought from him, but I've dealt with him before. Pretty bad when you've made so many deals that you can't even remember.

Brother in law had his 2012 Rubicon done here; http://www.4wheelparts.com/stores/St...fo.aspx?sNo=21

He worked with Zach who took great care of him, including follow-up visits to tweak some settings.

His Rubicon has a 3.5" Rock Krawler lift and he does some towing and was having issues with the 35s, so he had it re-geared. Ran around $1500.
