Yes it's the stock rear. I understand that it is "peg legged" but the awd setup worked well enough with the cam only setup. What's the most economical way to install a lsd setup that will work well. I realize there are 5000.00 complete rear replacements but was curious about upgrading the stocker.

Wavetrac makes a front and rear LSD for these rigs, we sell a ton of them here. The majority of the guys here that are making good power have the rears and a handful of them have the fronts as well. You don't need a complete rear 5k replacement to have an LSD, all you need is the wavetrac and a shim kit with fluids/labor and you're set, they go for $1295+sh and $75 for the shim kit, we sell the combo for $1225 shipped, save you about $175 bucks through us

I think you guys are missing the point here.....

It's a traction problem, Not his tranny, valvebody, or TCM

If you want traction you need to do 2 things.......

1) Soft Drag Radials

2) Get power to BOTH rear tires...The 1 wheel peel isn't doing jack shit.

Either a Wavetrac or Bills 8.8 rearend.

On a side note, Depending on where you live, It might be pretty cold out....If it's cold out where you live say goodbye to traction till the weather warms up.

I can roast my tires in 3rd gear in this weather.

You are short shifting because you're spinning so bad and bouncing off the rev-limiter, it shifts into 2nd gear and BOGS....

All you need are the 2 things mentioned above + a warm street and warm tires...You will find traction.

Here's an example of getting traction...

Warm weather

Drag Radials

8.8 Rearend

1300 HP...Launching on 5#boost on a 2step and tranny brake

One chirp and gone

If I can get traction so can an NA 426 build

Of course I can set it up to get traction. I was just curious how well the stock setup was working with around 450 rwhp. I build drag setups in the ls world all the time but this is the first awd mopar that I have built and was just wanting to discuss a few things with you guys. And I am the one who was asking about transmission stuff to begin with. Got tired of searching and just wanted an open discuss. Thanks for your input. Nice setup you have there too. I built my engine with 10.3 to 1 compression with thoughts of maybe adding a procharger with around 8 lbs of boost. I certainly will need a ton of drivetrain mods before going that route. This build is meant to be fun with AWESOME street manners and the ability to go high elevens on the track. The older I get the more I tend to gravitate towards "drivablilty, street manners, and reliability" first and performance second. In my opinion, it's an art to build a ride in this way and have it perform well too. If your goal is to go fast and it doesn't matter if it surges, bucks, is loud, rides rough, gets crappy economy, has a rear end that whines etc. it's a lot easier to build it..... just takes cash and research.

Oh and I would also like to say that if you get down to Northeast Louisiana in your jeep, come take me for a spin. I'd love to see just how civil it is running mid 9s. I have seen that video before btw.

If you haven't already, PM BuilderBill from Paramount Performance and tell him what you're looking for. He can adjust the line pressures on his Stage II valve body to reduce the hard downshifts you're trying to avoid. Until you're in a position to purchase an aftermarket transmission, a valve body and TCM from Paramount Performance would take care of most of your immediate needs. A Wavetrac LSD for the rear along with a softer tire compound (i.e., Nitto NT05) will help even more.

Good luck!
