ahh sweet, thanks POS

only difference would be the coil springs I have aye..

how hard is it to set up a system like that in the picture?

If I had that setup, and 4" lifted springs, would I still be farkin shockers?

Guys - there must be something that I'm missing. I get the fact that if the shocks are mounted /\ then they are moving less than if they were | | but where's the problem? Most people are using ranchos so this reduction in dampening can be compensated by upping the rate. So where's the problem?

Secondly, I thought the "bouncy, bouncy" was largely caused by axle wrap. If what you say is correct and I'm incorrect, will a firmer or softer shock rate reduce or enhance the "bouncy, bouncy"?

This may be off topic, but a lot of people are running Rancho's.

The new school of thought is running shocks like this --> | | as opposed to this --> / \ .

Is it true that Ranchos are apparently meant to be run in pairs.

Therefore, would this setup be OK --> // \\ :?:

My belief and knowledge is that running them / \ as i have had to
[didn't want to cut into floor at this stage] results in more body roll, would probably not be anywhere near as much with a leafy, but with coils the bodyroll [IMHO] is much worse, as the body has more leverage on the shocks, and i need all the stability i can get !! :? i plan on cutting into my floor and running 14/16" travel shocks after the jamboree in easter.

Damn you are going to run 14 shocks :shock: :shock: :lol: :finger: :lol:

Yes the Bouncy Bouncy is mainly due to poor suspension set-up and Axle wrap but think about how the shock would be working when they are angled in at 45 degress compared to Near vertical!

Try this (which i have) take the shocks out all together and see how much wheel hop you get then!!

On a leaf sprung vehicle there isn't much scope for setting up the suspension properly. How do you know what to look for. Are there any good resources regarding leaf spring setup? Does the gods of suspension thread on POR cover leaves? I want to find out how to work out where the best axle location (centre pin) location is for a given length spring and then what length shackle should acccompany it and how far the spring and shackle hangers should be apart. Is this sort of info available or is there any information to help someone like me develop more of an understanding of the finer matters?

Any guidance is much appreciated. Assume that I know nothing.

Each vehicle really needs its own set-up!

What works on one may not nessesary work on another!

I don't know what info they cover in that section on pirates most of the stuff i know comes from playing around with different springs and different lengths.

I think there is no real hard and fast rule when it comes to leaf spring set-ups.

You will find also a good, well set-up Traction bar will do wonders, i have seen some where they mount a shock to absorb and slow down the effect of axle wrap.

I've seen those styles too but they must have a very firm shock. Maybe a rancho at it's highest setting? If you've read my previous posts about my track bar you'll appreciate the problems that I've experienced with these monsters. I will be trying to sort this out on saturday with the help of a forklift to cycle the suspension.

I haven't even come across a spring manufacturer who really appreciates the subtleties involved in 4x4 suspension. Most of them just seem to copy each other.

Thanks for the suggestion POS

Bouncy bouncy - Cool terminology!

The one fore/one aft shock layout that toyota & others use does a lot to help with axle wrap in leaf spring rigs, as for the springs to wrap one shock has to compress and one has to extend. So it will at least slow down the "bouncy bouncy". Why the bundera has this setup I have NFI, probably more to do with keeping the shocks away from exhaust and fuel tank and other things that are in the way..

true i have moved my shox in more at the bottom(/ \) and it has given me a better ride and less body roll
