i gave my samurai a spoa with higher spring perches so it comes out to be about an 8inch lift and i have 32inch tires a few days ago i took it down the road to make a test run and it seemed really squirly which would be fine if i wasnt planning on driving it to school and back every day do you guys have any tips on helping it stay straiter also how many of you get yours going up to about 50-55mph does it feel really squirly/tippy at higher speeds im just kinda skeptical on it
thanks

What kind of steering did you put on it? If it's just your standard run of the mill Z-link, I would suggest some sort of cross over steering. Part of what you're feeling is probably bump steer.
-
Put OTT steering on it. I have that on my sammy, 6" SPOA and it steers better than stock.

As many have suggested, an over-the-top (OTT) steering system will eliminate the bump-steer -- when you hit a bump in the road (or on the trail) the steering wheel will jerk so hard that you may lose grip of it.
However, OTT will not fix the "baby-carriage" handling and driveline vibrations caused by your 8" SPOA lift. This would be ESPECIALLY true if you rotated your front axle to reduce the driveshaft angle at the third member! By doing so, you have changed the caster angle to the point where steering is borderline nighmareish!
There is an excellent article on the subject at northcoastoffroad.com called "The Six Inch Rule" that you might want to read.
An easy way to go to the page is to click on the link in my signature below, then do a search for "Six Inch Rule".
I hope this helps!

Ack, I've got a question for you.
I have TT OTT steering, and get no bumpsteer on the road or on the trail. However, sometimes my steering will just have a mind of its own if I don't hold on to it (on the trail only), and decide to go full lock left or right , taking the path of least resistance. This is while I'm stopped and trying to turn around.

Dihnekis, I think your steering box has dirt in it and a valve is sticking in there,maybe you could add a filter in the return line,if that does not do it replace the box.

It sounds like you have power steering -- something I don't have yet on my Samurai. I defer to mrfuelish's thoughts on the subject. Steering doesn't just "take off" at a complete standstill without some form of energy source -- a defective power steering system being a logical source along with vehicle motion caused by a tire breaking loose and slips off a rock while stopped evaluating the line you might take over an obstacle.

Sounds like you have negative caster ! Take to an alignment shop and have them check your caster.. I can bury my speedometer on the freeway with 36" swampers and still goes straight.

Breeze Industries (in Canada) sells a wide selection of aftermarket Samurai suspension and driveline upgrades, including a "crossover steering" system.
http://www.breezeindustries.com/kit_details.htm#Cross%20Over%20Steering%20System
Prices are in Canadian dollars so don't freak if they seem high-priced.
You can buy them here in the States at North Coast Offroad. I have a Breeze SPOA with the draglink instead of the Crossover system. It adds 4.5" of lift.

Other venders (listed here at ZukiWorld and at Izook.com) sell similar systems.

YOu might also look at SKY Man. for their crossover set up. It's a little cheeper if you're on a tight budget such as myself.
I have it and I'm really happy with the set up.
Here's a clicky to there site:

Crossover steering won't do much about the swaying. That's mostly caused by the 8" lift and any flexible items in the suspension (spring bushings for sure!) that are flexing under the 8 inches of leverage the spring perches are applying to the suspension.
Poly bushings (available at most online aftermarket stores) will help, but the best thing to do for a better daily driver ride is to replace the long perches with shorter ones.

ok if you have spoa lift combined with power steering i suggest you get a pan hard bar otherwise it will be all over the place ::)

What? Is this with a Suzuki engine in a Samurai?

i have no power stearing as of now does that make a difference
-
I got the 6" spoa on 31" swampers and it's a little squirlly on the hi way to, I put new shackles in (BREEZE) and it helped but not much.
I then put all new bushings in (ENERGY SUSPENION) that helped alot more but still all over the hi way, next I'm gonna try the pan hard thingy or the shackle reversal( I don't think I want the positive on road for negitive off road thow)
BTW the bushing are Urathane and $30 front/ $30 back Canadian at any auto store (just ask)

thanks alot im most likely going to make my own shackles same thing i have now only thicker and with a welded in brace i will probobly do it when i buy my bushings

you bet, a big 1.3

I,m with Eric on ...What ? 1.3 Sam engine ( even w/cam, Weber and header, blaster coil or whatever mod )turning 36s. Please tell us how you do this so we won't have to pay big bucks for larger engine swaps... Double cases? Clune V ? Nitro injection ? Micro gears ?
Your just kidding right ;D ::)
