It sounds like those Currie steering links go through a similar heat treating process as your TJ tie rod, right Gerald? If that's the case, then that's the last linkage a JK owner would have to buy.

Yes, 4340 heat treated. I'm going to give it a go and beat it a little next weekend. They are having a grand opening of the Azusa Canyon Obstacle course on July 14th. I've been asked to attend so I will to support our OHV areas.

Are all of the JK steering setups 4340, or was yours special? I was looking at it on Currie's site and there they claim it's 4130; we're looking at getting a JK in the somewhat near future, so I'm just curious. It's probably just nitpicking, but I certainly won't claim to be an expert in metallurgy.

Ill verify with John but that is what I thought he told me after the first batch proven too brittle.

Might need to go check out Azusa if I'm not busy! That place might finally be a good time (not a fan of mud).

Just finished programming the JKU with the AEV Procal and I really like the performance! I had to drive home from the shop to get the Procal and it ran like poop! Once I programmed the 4.88s it has fantastic performance again!

I've noticed the tranny takes a little bit to fluid up. So i'm watching this closely. I don't think I touch anything to do with that.

How come you didnt go 5.13s? Do you need a new power steering pump and box when going to the currie hydro assist?

No need for 5.13 in the 2012. The new 5 speed auto and new motor that provides plenty of power to be able to keep the 2012 in the right gear most of the time. We also like the larger pinion gear as we feel it is a stronger gear set.

PSC is working on a new bracket so we can replace the OEM pump with a higher performance one. A better pump is recommended as the OEM is a little bit slower than what i'm use to. Still the OEM pump works fine when off road and being able to turn makes navigating the rocks and obstacles much more fun!

I opted to send my steering box to PSC to be ported for hydro assist. It save $600-700 doing it this way. They put a new rear section the the OEM box.

The Currie axle is really close to ready for hydro assist. The brackets are alot stronger than stock so not as much work needs to be done to add hydro assist. The Currie HD steering is ready for HA with a bolt ram mount that makes to alignments a snap.

No need for 5.13 in the 2012? I wholeheartedly disagree, but won't argue with you. Surprising, given the rest of this build, unless this is planed to be a show rig only? But then pinion size wouldn't matter...which I wouldn't think to be an issue with a deeper gear set in a custom currie axle, in the first place...

Agreed in a 2007-2011 you need the deeper gears but on 2012 you don't.

Unless you've driven a 12 with gearing you can't understand how much better these drive then the early JKs. This thing just peels out and we still like to drive 80mph. This rig will do everything but the Hammer trails. It is not a show queen. This is my only trail Jeep now. Everything is gone!

With a hi-pinion rear, you want the larger pinion and since this motor puts out 285 hp, it can break stuff. Unlike the anemic early models.

So here how the JK sits with a Currie 4" suspenion lift. I imagine it will settle a bit as I only have 50 mile s on it. Also need to install the bumpers, rockers and Falken 37" tires.

Okay, I'm more likely to fold to someone who knows their biz...so I'll woefully accept your explanation.

However - I do own a '12 Sahara with 3.73 and auto, and I'm not beside myself with the improvement. Plus, I really like that deep granny first gear in the rocks

Edit - looks awesome...perhaps I overlooked this, but what tires do you have on there now? Temp loaners from another rig?

Maybe if you had a real transmission haha youd want the 5.13s. Great looking jeep. Cant wait to see the results when you get the bumpers and everything else on.

Alright, I believe you as well. I had the 4.10s and they were fine with the 35's. So, today I was driving out to the shop at 80mph and doing around 3200 rpm. I don't want to going any higher than that!

I'm looking forward to putting on the 37s and seeing where I am. Currently 35s.
