my 12 jk.. with automatic and 3.21 ratio

after i lifted and put 34' nitto trail grappler it is sluggish...

I'm kinda feel confidence enough to go death valley travel this weekend..

does anybody run 3.21 gear with some big tire? how was run it on offroad?

chris@offroadevolution

it will be fine offroad. It wont be the best, but its not something to cancel any trip over

I had my 12 jk running on 35s and 3.21 for 5 days then i swapped my gears to 4.56 ,,,, IT IS WORTH IT !!
u will get the torque and hp when u need it

it's not great, it definitely goes faster in 4lo than everyone else will which makes it a lot more difficult to control. It's a pain with a manual. Regear when you can. Until then enjoy it, and enjoy having money in your bank account.

Did you reprogram? I'm about to put 35" nitto's on mine with 3.21. I have a procal sitting here and just waiting on the tires to arrive. I hope it helps a little for things like avoiding "limp mode" that i read.

I think I saw your Jeep today, are you running it with an arrow as an antenna?

theZombie

I don't think that was me, however, a bow arrow for an antenna would look wicked cool! I like that idea

Yeah it was awesome and wish I wasn't driving on 1604 to get a shot of it. Definitely a Walking Dead theme old school for sure.

I did ... aev procal

it obviously help but also you obviously feel loos power and sluggish compared with stock..

I need regear as soon as possible,,,

chris@offroadevolution

i agree you need to regear, but I personally would never miss an offroad trip because of it
