Before I start, I already have read the stickies and tried searching for my answer, may be a dumb question but to me its reasonable.

So, I' picking up my 35's this weekend for my 2012 2 door. 3.6 and 6 speed manual. I have 3.21 gears right now.

I plan on purchasing my gears soon, either 4.56 or 4.88. Some people say 3.21s are "tolerable" but as a DD and trail rig I don't want "tolerable". My original plan was to get gears then buy tires but I'm getting a sweet deal on a set.

The question is since I have 3.21s do I need both a front AND rear carrier, or just a front carrier.

Thanks!

 

Front and rear. Check with your gear installer as they will know just what you are going to need and they may have used carriers laying around their shop that they could use. The ones that say it is tolerable are just deniers that don't want to spend the money. Without proper gearing performance drops both on road and off road, even with bigger tires off road you will have to use momentum to throw the jeep at steep obstacles. This is more likely to result in broken components such as broken axles and wear on ball joints and unit bearings.

 

with a 6-speed?? How flat is your terrain?

35s with 4.11s was tolerable. I can imagine with 3.73s will be sufferable, with 3.21s I can only imagine it being miserable. Not being able to get into 6th gear is one thing, but you have to worry about starting from a start as well.

Are you getting all new wheels and tires? Just throw them on and drive around with them and see how terrible it is. Hate it that much, just throw your stocks back on it until you get gears.

 

Appreciate it guys. I'm getting just the tires as I already have wheels. I may just pick them up and wait to install them. I agree, the 6 speed may be tolerable if you can get it moving. And for the gears, I have somebody back home to install them whenever I get home on leave, unless someone in the Carolina area wants to help a man out.

 

New carrier front only, it's a D30.
The rear is a D44 and will not need a new carrier.
There's a few threads on here about regearing and if I can locate a good one then I'll send the link.

 

With 3.21 I believe you need a new carrier even if it is a D44

So by the links you posted this statement is not correct.
