SAS on Trooper

[das_jeepinator]

I'll try to keep this short and simple. A friend of mine wants to do SAS on his trooper I think he's decided on "Toy" axles front and rear so gear match isn't a problem in this case coil sprung rear. leaf sprung up front.

Other than the obvoius brake lines driveshafts and what not what about the steering should I swap in "Toy" steering box or:confused: hydraulic steering isn't an option I believe.

Yes I have experience with Troopers having owned 2 myself and my dad swears by them personally I like my Jeep and 2 FS Bronco's

But as far as SAS on a trooper goes this will be a first any links or ideas on what I should do.

The reason for "Toy" axles is they are roughly the same wms to wms as the trooper is.

Any ideas will be greatly appreciated TIA

Thank you very much oh so not "Stewpid" one:D

because the trooper's are taller and boxier...= top heavy

i like to see a wider trackwidth.

most popular choice by far right now is the Wagoneer Dana 44's. Few inches wider to compensate for the height. Gears for the stock rear are available up to 5.38 and there is and ARB available...or you can weld it.

i have done a few SAS on isuzus......here's my curent rig buildup. maybe some helpful info:

What Trooper? '92+ or the earlier toasters? The Toy mini-truck axles will match the old Troopers pretty close, but the '92+ are a bit wider with axles in the 63" range.

Swapping to a Toy steering box isn't needed unless you're wanting a box that mounts to the outside of the frame rail. The Isuzu box is quite substantial. Porting it for hydro assist is tricky. It's very difficult for the one port, but I know West Texas Offroad is doing it. He ports the the passages too I think for better flow.

its an 89 trooper as far as steering went that was the only major if I had a problem, problem that would show up that I could think of thanks for the info it could and probably will come in handy for other Trooper owners as they join pbb

keep us posted as you get into it

no problem, it'll be a while before we start on the trooper right now were in process of putting a yj tub on cj7 frame it'll have the cj7 front clip and yj tub. Rest assured I will be abck with pics and such as we are doing the Trooper build up. Looks like my bro-n-law is going to sas his trooper as well now.

He already owns it and wants a Jeep not that, that is a bad thing mind you:flipoff2: me being a jeep guy and all but the Jeep he wants for the pirce and what he'll want done to it. I can build his trooper and then some and with the help from you all on the links to built troopers. He's liking it better each day. Once again thanks for the links

hey i've got the same set up on my RS, yotas front and rear. check out my webpage, should be able to help you out. steering is very easy with toyota, ship your pitman to sky-manufacturing.com and they can ream it from the bottom to take a toyota tapper, then just order your draglink and tie rod the correct lenghth with toyota FJ80ends.
good luck, keep us posted

What Ram are actually running for hydro assist?

I have the problem that Isuzu box is not able to fully lock Toyota steering left to right, do you have same problem?

This is likelye a geometry issue, and not a box issue... the Isuzu box sweeps plenty of arc. The Isuzu pitman arm is much shorter than the Toyota pitman arm, though, and if you use a standard Toyota arm at the knuckle, you wind up with too little sweep.

I went with a toy FJ40 axle up front but I widened it :eek: It hasnt busted yet. It was easy because I could get my hands on one, then I put in 4.56 gears to match the trooper rear and badabang.

As for steering, I am running 36x14.50s and still have the isuzu steering box with a dropped pitmann arm. Not to say that I wouldnt rather have an AGR rock ram but hey, it still works :D (and it works with an ARB up front)

good luck,

Got it, but I would like to know if Isuzu box is able to handle a 1,5"X6" ram assist device.-

There's pictures in this link of Rob's set-up: http://www.4x4wire.com/forums/showflat.php?Cat=&Board=UBB68&Number=369357&Forum=c15
...and even more details on tapping the box in this thread:
http://www.4x4wire.com/forums/showflat.php?Cat=&Board=UBB86&Number=327669&Forum=UBB86

FWIW, IMHO the Isuzu steering system is as overbuilt as the rest of the truck, and works fine up to 35-37" tires, IMHO. Mine heated up with hard use pushing 35s, but still turned them effectively in all but the most bound-up wheel-against-a-boulder rough stuff.

Handle it? yes, but is far from ideal. If all you do is drive offroad, i'd say go for it. But tapping the Isuzu box for hydro assist is tricky and very difficult to produce favorable on-road/speed handling characteristics, so be forewarned!

But nonetheless, having hydro assist offroad is awesome! Though having done this with the Isuzu box, i now find myself considering a steering box swap to box that produces more flor and more favorable to hydro assist.

And what box you think is able to reach reasonable on road manners?
What about Toys IFS box?

Dibs on your old box and lines if you decide to change! :D

I dunno, i'm not an expert on steering boxes and that question would probably be better suited for some of the guys in the gen4x discussion.

All i'm saying is the Isuzu box is a little sluggish. from what i understand, there are things you can do to pump it up a little furthur, but not without odd characteristcs like always wanting to turn to one side and other things that make it even more scary for the road and speed. basically sluginess is going to be a limitation of the box should you choose to use an Isuzu box for your hydro assist.

[Independent4x]

rob what is the ratio on the isuzu box? do you know off hand?

My '86 is 15.8:1.
