Hey guys, thanks for the opinions on the shackle angle. I have some follow up questions. I do not expect to go SOA ever. Some or all of you SOAs probably said that, but I mean it. <IMG SRC="smilies/biggrin.gif" border="0"> I am trying to set everything up for a one time modification. With that in mind, here is my situation on the current suspension. It is an old superlift 2.5 and it is not soft and not flexible. I am thinking about getting a pair of 4" FJ55 springs from TPI and then experimenting with leaf removal, shackle length and position until I get some more flex in the rear. What do you think?

I have a shackle reversal on the front and have the same vertical shackle situation there as in the rear. I am getting better flex in the front, but the road ride sucks. Any opinions on the front suspension?

Again, thanks for the welcome to the board and for any opinion. BTW, Nolan, I'll try to get some pics over the weekend and post.

Don, talk to Nolen about the SU. He got a ton of flex out of a set of alcan springs that he had made. They are probably your best starting point. I tried to get National to make me a spring pack that had some lift and was very flexy. The problem with springs like this is that they can wear out rather quickly (read sag). But you should be able to get some reasonable flex by altering the shackle angle and getting a different set of springs.
What applies to the rear should easily apply to the front.
Which Sr do you have?
Most of them are really nice rockfinders. If the rig is mostly for on road use then it is not a big deal. However off road they can be annoying. I prefer the standard shackle in the front on Spring under vehicles.
One thing you might want to consider if you do not mind cutting your fenders is running fj55 rear springs. They give a bunch more flex than the 40 springs. If you open the spring clips they droop beautifully.
Also there are the orbit eye springs. I believe that they are available for 40's now.
Hope some of this helps!

Mace, unfortunately, the SR was one of the mods. by the PO <IMG SRC="smilies/mad.gif" border="0"> and it is of the rock finding variety (Advanced Handling). For now, I think I will get the rear worked out and then deal with the front later. Thanks.

Don,
Order yourself some 4" Alcan springs. Have Ken make them 3 inches longer than stock and center the rear spring pin.

In the front, have them made 2 inches longer than stock and have the pin placed in the center.

With the SR, you will not have problems with the front fenders as the tire will go back into the large opening in the fender under compression.

After you get the springs ($870) delivered to Dallas, get some flat bar and experiment with shackle lengths. This way you can decide the perfect length to the springs and then you can get some HD stuff and make your shackles.

Come to 360 Sunday and check out my homemade shackles.

After you do this, you can flex it up and see what length shock will work best.

I suggest the Rancho 9000's for a trail rig.

I keep my rear from bouncing when I am "getting it" on hill climbs by cranking them up to "5"

As for the front "Rock-Finders", you can do a flush mount Shackle reversal as long as you cut/turn yor knuckles to correct the caster and still stay spring under.

Come out to

That should be flexy <IMG SRC="smilies/biggrin.gif" border="0">
Thanks Nolen

Thanks, Nolan. Can't make it to 360 this weekend. Taking my wife to deer camp. Damn, this deer hunting is getting in the way of wheeling--maybe its time to sell the guns.

How do I contact Alcan--didn't find it in a quick internet search. What is special about Alcans?

I've spent this week getting the winch remounted to help shift weight forward. I think I will move the spare inside also. <IMG SRC="smilies/usa.gif" border="0">

Ordered 4" Alcans just about 2 weeks ago for my Piggy.

They are due in on the 5th of November, so I will let you know how the install goes.

I am going for stock shackle length, with extended brake lines and shocks.

Once the Alcans go flat my Piggy is going SOA however. I hear they last quite a while, but will try to keep the board up to date.
