JK Show & Tell Whether they're just poser shots in your driveway or hardcore action shots on the trail, if you've got photos or videos of your Jeep JK Wrangler (or any JK for that matter that you think is worth showing off, inside or out), we want to see them so please post them here! Likewise, if you are wanting to see a photo of something specific like an aftermarket JK part or poser shot with a specific setup, this is the place to ask for it.

I'm talking gussets, inner and outer sleeves at the very least. And don't really plan on a locker at any point with 5.13s and 37s.

I plan on eventually running 37s, but not until i wear out my 35s...and get 4.88s, diff covers, C gussets, inner and outer sleeves, a Super 30 kit which upgrades the 27 spline to 30 spline, and an ARB locker... Should be good for what I do...I'm still debating whether or not I want the lockers or not
Well that was my general plan to but I didnt know about the 27-30 upgrade kit, ill have to look into it. Also I never planned to lock the front

plus my 35s have been doing great with all the wheeling I've put them through. 37s might be overkill, but they will be going on in the far off future when this rig is no longer my dd

The Super 30 kit is the shit. And yeah, lockers are wonderful to have, something that I want, but they can reep havoc if you wheel hard

Haha I think were on the same track, eventually when this thing gets too many miles on it I plan to get a more economical car and use this as my project/toy, thats when Ill go way extreme with it

Can you direct me to this super 30 kit? I really appreciate the input by the way

Edit: found it, just need it without the locker

If you have an automatic, you need 5.38s with 37s. I have 5.13s and I had them installed with 35s. If I was doing it again, it definitely would be 5.38s.

Will you be getting new wheels for 37's?

There is no 5.38 gearset for the D30.
