Really? From the SAS's that I have followed it seams that the short front shaft and high driveline angle is a frustation for people. I thought that if I could gain a few inched at the axle and lessen the driveline angle I would be saving myself some headache at the end.

What YJ springs did you use? Factory Jeep? Procomp? How much do/are they arched?

I am trying to find a combination that have the springs almost flat (just slightly arched) while on level ground. I am planning on giving up a little uptravel in order to keep the lift as low as possible.

They are rancho 44044 yj leafs... I think they are supposed to be near 2 inch lift springs for a yj. They have a good amount of arc in them, I would be very suprised if you could even do an SUA SAS with flat springs...

As you know, Im sua, in the front with a wagoneer 44... I have 31.8" tall tires.
When I measure from the ground, up to the middle of the front wheel well, its 41.5 inches high... Are you trying to go lower than this?

44044 are orignally a Wagonner application. I'm not sure if thats interchangable with YJ springs. Something tells me YJ springs are a tad shorter.

If you're considering YJ springs, one attractive option is the 3" lift springs from BDS for a YJ. I have a friend who used these on his ZR2 Blazer SAS. Best thing about them is i believe they're considerably cheaper than Rancho 44044. His truck has a very similar stance as when mine was on 36's.

Actually, I was wrong all along, they are "Rocky YJ-25"
So I'm guessing they are a 2.5" lift leaf...

I purchased them from www.partsmikeparts.com, and he had them listed as yj 44044's. I dont think he the sells springs anymore though...

But yes, they are shorter, about 2-3 inches, which is why I chose to use them.... <img src="/forums/images/graemlins/kewl.gif" alt="" />

I dunno, the key on this was that I put the shackles up front. So I am running only a standard 6-8" bronco slip in my front driveshaft. I could probably get by with something like a 4" slip because my driveshaft just doesnt move that much. I do have an automatic, which helped my angles out quite a bit, something on the order of an 3"-4" of front driveshaft. I am certain that if I put in a CV in the front driveline that I my vibrations would just evaporate, I just haven't found this essential. If I go into 4hi I can go like 20MPH, in low only like 10MPH and pretty much I just don't have any use for 4hi anyway. I never use 4wd in the snow anyway.

I moved my axle forward about an inch maybe a little more. My total wheelbase is 111.5" now and my rear is moved back about two inches (I figured cutting fender doesn't hurt as bad as cutting doors ).

As for cost on my rear driveline that was expensive, but I got a good quality product from high angle and I will recommend them to anyone.... it is just good stuff.

FYI total budget on the truck probably worked out to just shy of 5000K including lockers gears axle bomb proof steering, springs and all the other stuff I had to buy. I still don't have the tires I want either. Gears to come shortly.

One more thing, as for width, that is what I would decide first when going SAS then you go from there. If you can be full width, DO IT! It will be cheaper to get a 60. If you can't that it can be expensive....

80 series stuff is kinda wide it would be hard to pass inspection here in utah.

for steering if you have regular box you can ship the pitman to SKY-manufacturing.com and they will retapper it to take an FJ80 TRE from the bottom for only $40, then you can just get regular toyota steering. i'm not sure if the newer rodeos have a steering box, i know some are rack and pinion, if so never mind. And i say go for the FJ80 axles if you got the cash, they are bad <img src="/forums/images/graemlins/butwiggle.gif" alt="" />

OK, after all this discussion I really think that for a first timer the 80 series axle is the great choice, for its width, birthfield strength, high pinion, etc. It will cost a little more up front but I think will offer a little less work in the long run. The YJ springs are probably a good idea also, they are a little shorter that 44044 and will help move the axle forward the needed 2 inches to clear large tires. The only issue with the FJ80 is the tie-rod, you will have to go with a spring over set-up or use the radius arm set-up. A spring under set-up it not a option with out a lot of work. If I were going ahead with it I would probably just do SOA shackles forward, you might give up a little flex verses shackle reversale, but mounting, ride height, and drive shafts issues are a lot less with this set-up.

As for my Rodeo, it will be reduced to a kid hauler and grocery getter before being retired from this family for a mini-van by the end of the year, my wife and I have decided to go to the dark side and get a Wrangler. With 2 small kids (3yrs & 3 mos) I don't have the time to put into a SAS. I am excited that I will be able to have a fun weekend/off road vehicle, but I am not really excited about joining the 10 billion member Jeep club or having a vehicle that looks like a million others on the road. I plan to stay on this board since I feel this is one of the greatest 4x4 communities around.
