That is one of the big arguments with the left coasters and the right coasters. The people from out west swear by the shackle reversal and the people from the East swear by the shackle up front.

There are some pros and cons of each and I think it would be a personal preferance to do which ever one you want.

With the SR you need a long travel d-shaft cause while the axle droops it will extend the d-shaft a long way.

With the SR the shackles are not out front making it easy to hang up on rocks.

With SR while under compression you loose wheelbase.

I am sure there are more and some people will chine in with them so you can make a desicion.

I ran the dreaded 'fangs' for about 2 years here in the rocks.
At first I had set up the suspension so it was very loose - great for articulation in the rocks. But it came at a price. With long front shackles and loose rubber bushings, I had alot of wheel-wander when driving down the highway. I went to the S/R setup to get things under control. I had to get a long spline front driveshaft right away. I also started hitting the ledges more often because the fangs hung down so far. It did hold up pretty well, so much that I sold the kit for a good price when I finally got rid of it.
If I had to build a street/light trail rig all over, I would consider using it again. But I wouldn't be using it on the trails I do now... it wouldn't make it.

With the Calmini S/R...

And a few suspensions later - YJ's...

West Coaster here. Love the SR. When you heard long drive shaft read that as follows "long spline" Extending the ds won't help. What I like about the AAPA kit is that I was finally able to end tire stuffing. I don't run bump stops anyways but moving the axle forward 2" helps a ton. It isn't just whether you run SR or SF it is the springs. Go the whole nine yards and get the yj kit. IT truly is the cadillac of rides for the ZUK. You will have to relocate your shock towers or better yet make new taller ones and running HD good quality shocks is a must. Remember the spring is lower in the rear forcing your dif down so your perches have to be at the right angle to get you back to the correct castor angle.

I've ran SR setups on three Zuks and currently have one on my DD along with 3" lift springs. I don't buy that having the SR will hang up on rocks . Any suspension will hang up on rocks If you don't take the right line. I have absolutly no wheel vibes or steering wander. and the truck drives strait as an arrow down the road. Off road it works ok but isn't the flexyist setup out there. But for the wheeling around here that I do with it the SR works great.
