X2 on a pair of Truetracs. Doesn't sound like you actually 'need' thousand dollar selectable lockers, so those will be a great bang for the buck traction boost.

 

Thats kind of what i was reading as well.


user error........ Not much I could do hitting 2ft snow drift for 1/8th of a mile.....rear wheel spin and opposite front spinnage....Theres always one in the crowd.

 

Yah no rock crawling here in MO. Maybe when it gets older. Its going to be a slow build and for now its what my wife hunts and goes to work in.

 

I'm not saying your jeep should be able to cruise flawlessly through feet of snow. I'm saying you should start with a solid understanding of how your equipment works and what its limitations are before you start blaming your "4x4".

 

As far as Jeeps go I will say im new to it and have learned a lot from here. However I grew up on a farm...tractors, trucks, 4 wheelers. I feel like i have a pretty good understanding of 4wd...I am just used to my trucks and other things that put all the tires to use when locked in 4wd.
I just was saying i dont care for my tires to not turn while in 4wd when i hit the skinny pedal. This jeep is the only rig ive tinkered with that has done this....I guess i should have wordered what i was saying differently. Im not a rock crawler, but do frequent mud. I just would assume with full power to all wheels would seem better to me then the vehicle deciding which wheel to give power to....

I guess what im asking is I want my tires to turn when i hit the gas. How can i do this...So far truetracs.....
Now if you want to help me out. focus on this and not that you are a superiour jeeper...lol
sounds like from my reading a d30 with a 513 may not be a good choice to put a truetrac in? so possibly just put one in the rear while im doing gears, then later on swap in a d44 up front and continue on.

 

It's not the jeep deciding which wheel gets power. Take each axle separately for a moment. With open diffs, an equal amount of torque is applied to both tires (left and right) simultaneously. When one loses traction that's a 'leak' so to speak. The open diff can't transfer any more torque to the other tire, than it takes to break traction. More aggressive tires will help increase traction, or truetracs and auto lockers that you're talking about. Much easier to break things with a selectable locker.

 

Lightly applying the brakes would engage Brake Lock Differential no?. I'm not trying to beat on you but maybe look at this experience as a reason to learn more about how the system works. I have played with mine and really learned how to use it.

If you are gonna do a locker, start with the front. It will only work when 4X4 is engaged versus if you do the rear which will result in fishtailing in mild snow or ice when in 2WD.

Maybe the Super Duty has a trak lok rear and your JK doesn't ?

 

Ok I would put a locker in rear or a selectable at that it will lock when you tell it to. Everything I read advised against putting a selectable locker in a D30.

 

Yah thats what im coming across tonight reading...

My superduty once in 4x4 all 4 wheels dig no matter what, all TCS systems are off.......

As far as tires on the jeep, im currently running trail grapplers. I havent played much with the 4wd system either as i dont drive it that much. My half ton i used to have engaged the rear and when applying lightly to the brake also. You also had to hold the 4x4 button for 5 seconds to completely disable the TCS, if not even in 4x4hi it woudl cut power to the wheels to keep from spinning, which i didnt really understand the purpose for...

So basically once i get used to this Jeep 4x4 I will be alright, BUT.........while im doing the gears may as well throw in a true trac in the rear

 

I'm not sure why you are seeing a performance difference with the JK. Maybe your previous trucks were bigger and heavier, giving the tires more grip before one started spinning?

I am one of the folks who is not a fan of dropping thousand dollar selectables into d30's. Plenty of people are locking them and having no issues, but just from the cost perspective, for roughly the same price as 'fully' upgrading a d30, you could have a 44 instead. Makes more sense.

There are plenty of threads here on the truetrac, be sure to read through several before deciding based on a few replies in one thread. (But, I think it will be perfect for your needs.) $375ish for the front and $460ish for the rear. May as well do both...
