35" Tires with 6-Speed and 3.21 gears?

2009 JKU-X

Am I going to hate this?

I'm leaning towards a 2.5" BB (Terraflex) with 1.5" spacers and the stock 17" rims.

I ran this for 6 months. If you don't want to climb a hill or haul anything, then you'll be fine. It's not that it isnt driveable, it's just a dog. Funny thing, the highway driving will get you some descent mpg.

Try it for yourself... only way to see

Personally I think you'll be fine... just downshift to 3rd for hills.

Do it. Regear when you can. You will regreat going with 33's. Like I did. I sold em for 35s. I have 3.73 gears though. The 6 speeds handle bigger tires way way way better than the autos.

Had 6spd with 3.21s when we got our 08 JKU X. When we put 35s on, it wasn't as much fun to drive. I found a set of d30/d44 open carriers with 4.10 ( which are now for sale) and it was a ton better!

35's with a manual transmission will work better with 4.88 gears.

Or you could just throw out four years of a built up experienced knowledge base. It's not like it was in 2007 when everyone was trying to figure this stuff out because the complete redesign and an engine that operates in a different power band than the previous.

Of course it all boils down to what you are actually going to be doing with your rig. Wheel every chance you get? 35" and 4.88, highway driver with occasional trails? 35" and 4.56
4.10s are tolerable for daily driver with light trail duty.
Chart will give you an idea on what it'll be doing

Highway it should be ok. I was running 4.10s with 35s and it was fine, usually had to drop to 5th to climb a bill at highway speed, obviously with 3.21s you'll be on the shift a whole lot more. Where you'll really be unhappy is on the trail. Moving so slowly, I hated my 4.10s in high range, but I only like to drop it to low range when I need it for crawling. Picking up the rig tomorrow, had 4.88s installed this week.

What does it cost to re-gear? Is it a DIY job?

Absolutely not. It will cost a minimum of 1000 dollars, labor alone a lot of the time. It depends on where you go. Connect with some local 4x4 people in your area, who know mechanics that are willing to do it cheaper than what a normal shop would cost. I meet a guy at a local tire shop who goes offroad a lot with his ford pickup and is very knowledgable. Hes done multiple regears on his own and others rigs and offered to do both front and rear axles in mine, 2 hours labor each axle, at 80 and hour. Not bad at all. Bout a third of the price as what a regular shop would charge.

Wow you got a great deal. Labor for mine cost $900 plus the parts which was about another $700. Not a cheap job, it's also a good idea to put some heavy duty diff covers on at that time if you're doing much off roading. I went with the ARB covers at about $175 each. Running 35s is a pretty big investment, $5000 is not a bad estimate for doing the whole job including lift, rims/tires, gears. That was with me installing my own lift.

Yeah, it is a great deal, I am happy that I meet him! I dont plan on regearing anytime soon though. Im honestly fine with the performance of the 3.73 gears and 35s on road. I concentrating now on getting my lo end gearing down/crawl ratio up. Currently in search of a used/new rubi xcase. That will provide more low end gear reduction than a differential regear would.

I'm fortunate enough to already have the 4:1, I can say for sure though with that xfer case you absolutely don't want to be running low range all the time. I found the 4.10s to be acceptable, although not ideal, on the road, my biggest issue is running high range on the trail, it is totally gutless. If you go 4.88 or 5.13 you will be fine with your current xfer case, promise.
