sway bar ????

How do you figure out what rate sway bar you need? I know that if you change what hole you mount it in the rates will change, if youre linkage between sway bar arm and buggy is not 90degrees verticle because of changing hole position will it matter as long as you have complete flex without binding. Thanks for any help..

i also have some general question about sway bars and mounting? is there any bible on this somewhere?

I don't know anything about them, but I will be attempting to fashion a Currie AntiRock sway bar on the rear of my 4Runner in the next few months...

Let me know how that works out for you Pooh i need something too! way to tippy from soft springs:awesomework:

I'll get in on this too...JasonC, what are the pro's and con's of a system like this. Never seen a arm that short and wonder if is beneficial or not.

To my knowledge there isn't much(IF any) of a selection of different sway bar rates. You can fine tune it by changing the arm length--as that changed the leverage. Longer/lighter and shorter/heavier. This is what I got from my dealings with them..

There are different bars out there Crash, just got to go beyond the world of rockcrawling.

Length of the sway bar and also the diameter of the bar changes how stiff it is as well.

I plan on running a bar that goes in between the frame rails of the Runner as I don't have room between the tire / frame / fenderwell for the arms to go out in that area...

So I will run one between the frame rails with pretty short arms, and the arms will be angled slightly down to keep them from hitting the bottom of the tub on the back.

If it ends up reducing rear travel, so be it... as long as it makes it feel more stable and reduces alot of the body roll that I have.

You mean world of wheeling. If you ventureout I am sure there is tons of stuff--but this is for a wheeling rig not a race truck

here is a sway bar rte clculator that I while searching Pirate http://www.buildafastercar.com/tech/Sway-Bar-Rate-Calculator

but still dont know how much sway bar I will need.

holly **** stan does exsist

i have one 28" long i cant really use (bar and alum arms). how wide are your frame rails?

Your going to want a swaybar in the rear Hip... jsut get different length bar.

ya for sure, he needs a longer/wider one

talked to Tony at Rock Equipment and he gave me a few pointers for my set up. I already have a 36" .75" bar and arms that I bought used of this board a while ago. The arms are 14" center to center, the axle end will be around 3-4" higher then the sway bar end. At the arm end on my axles to place the lower mounts a couple inches wider then the arms because as the axle drops it will swing in.

yeah i know i will need one and someone gave me one its just too short for my frame rails.

unless i mount it to the axel truss and run the arm up to the chassis. i would like one a little longer as where i want to put it it barely touches the frame rails:eeek:

so any one wanna trade? mine is 28 inches long and i think its 1" dia. ill measure when i get home tonight.

This is very true but anti sway bars for go fast rigs have not been nearly as successfull in off road rigs. I've seen numerous car bars strip the splines out of the arms because of finer splines (I've also seen a couple of broken bars). A car bar only has to twist a very short amount where an off road bar could twist over 90 degrees. Sure you can save some cash but at what cost? The off road bars are designed to hold up under a greater degree of rotation.

'Ya pays your money and ya takes your chances'

ok so i need to get the whole new setupp as i cant find a torsion bar with the same spline size as what i already have. so anyone want a 28" setup? a new setup costs $390 plus shipping.

i need a 32" setup anyone got one?

I said out of the world of rockcrawling not offroading.

You could look towards desert racing stuff but that stuff is plated in gold.

To answer your question Stan it's mostly trial and error. If I were you I would get the heaviest bar you find and go from there.........
Couple typical issues I've seen with these bars on off road rigs are the splines stripping out and bars break as stated earlier. First don't use aluminum arms. Hip get steel arms!..Second use the longest bar and longest arm you can make work. Offset the arms if you need to to make a longer bar fit. This way the bar itself will twist less at a given wheel travel. Also retorque the bolts often that clamp the arm to the bar and use lock nuts. On mine I also put a snap ring on the end of the bar with a large flat washer. This helps keep the arm in place if the bolt comes loose..
