Tyre diameter can be increased by 15%
Body lift is 50mm (certificate needed)
SPOA is a big no no if it is used to increase ride height.

In Queensland, to be legal:
Spring lift must not alter bump or rebound travel by more than 1/3 of factory specs. If you've only got 3" of travel in either direction, you're limited to 1". But there's a rumour that the regs recently changed to a flat 2".
Tyre diameter increase is 15 millimetres - a pathetically suckful amount. 15% would be much more reasonable, so don't hold your breath...
Body lift - yep!
I always thought SPOA is purely and simply a no-no. Please excuse my ignorance, but why would you do it if not to increase ride height? HOW could you do it without increasing ride height?

Cheers,

Scott

Any proof to this rumour? If the rules have changed new ones would be released.

The QLD rules state that doing an SOA conversion is not permitted as a means of lifting a vehicle. But when I discussed it with my engineer he said that it would be possible to approve in QLD if the vehicle remained unlifted. SOA can have benefits to suspension performance.

otherwise 2" it is

A lot of people have mules here. Whats up with that and why is yours in pain?

you want to save "x" and buy cheap coils from the 4sale section, then spend "x+1000000000000" to get custom leaves made up in the rear? I'm no bean counter but i'm sure it'll end up costing you more than buying a pre packaged kit or even a half decent custom all round job.

decide what rubber you want first, then decide the amount of lift, THEN see what options are avaliable. Otherwise you'll just spend plenty for what...?!?!?! So you could feel great about buying something cheaper than what it would have cost in stores....

mickyd555 wrote:yep your absolutely right gonzo........a coil cab has got coil springs........under the cab

coils on the front and leafs on the back

I don't own one but I have always thought that COIL CAB referred to the all coil version.

So I checked the trusty internet and whenever anyone refered to a COIL CAB there were pictures of a Nissan Patrol ute with coils all round.

i think mickyd555 would know whats under his own truck if you looked further you would find that nissan brought out both being coil front leaf rear and coils front and rear and i think only in the last couple of years they have had coils allround only

I think if you read my post again you would see that I never said that all coil was all you could get. In fact I referred to the 'all coil version' which suggests there are other versions such as the front coil and rear leaf version.

Extremely exciting revelation I know.

right and your point is what i was saying if you looked abit further into it you would find the other ones you can get and to also let you know that there are different types if you dont want to find out info on different model trucks dont read the posts

Well considering how STUPID this tangent is this is my last bit. I NEVER said there was only one type I was merely pointing out that his coil/leaf is not a coil cab. If he was to ask a shop for a lift kit for his oil cab he would get the incorrect info. I am well aware that that Nissan Patrol utes have suspension type choices from the factory.

Touchy aren't you

touchy no just right i didnt say you said there was only one type i said you have a look further you find the other ones and iam merely pointing out that his coil/leaf is a FARKIN coil cab and if you are taking about a simillar truck with coils allround you just say coils any suspension shop is going to know what you are taking about they were sold and promoted as coil cabs by nissan themselves

thanks muduppig, i thought i was right in saying it was a coil cab.........

to everyone who said i was wrong............

Have you contacted any suspension shops to get their suggestion?

if u want costom springs made for a patrol i can do them , cost is about $220 including tax and they will have to be reset as well cost $ 225 ., as for soa iv'e been talkin to differant springs places and mechincal shops around qld , iv'e been told that m/roads and the stiffs are lookin at changin the rulin on mods so qld and nsw are the same but it wount happen till late in the year . so lets wait and see .lets hope so .

If qld rules are changing to be same as nsw than thats good. If nsw laws are changing to be equal to qld, then thats farked.

But ive heard nothing of any rule changes from the rta?

hey humphrey, Are those prices for each pack, or for a set of two ??

But could you argue that a lifting a vehicle 1/3 of bumpstop distance over factory by SPOA conversion was Legal?

That would be possible for vehicles using very long flat springs with reduced leaves in a pack.

Dave.

Probably not relevant but other day I looked under one of those newer F250 trucks with the leaves front and rear and was surprised to see the front leaves were inverted- that's right not flat, but inverted giant long things on almost new truck (ie standard not sagged).... SPOA like that would easily keep the height down.

mate thats for the pair ,

The coil cab was released in 1992 as the GQ ute with all 4 coils. The front coil / rear leaf spring configuration is definitely not and has never been called a coil cab. End of story.

if thats the case whats the later called you work for nissan do you

HTF you work that out ???? 2 equally sorted leaf suppension systems one sua the other soa show me where there is a difference in the forces applied to give a increase in supension performance ???


only bonus is the springs are out of the way and u get a few inches lift without increase in arch height

exactly that, you get x amount more clearance, with springs capable of the same amount of down travel.

you also gain uptravel, without loosing down travel.

sometime iread something about different forces at work, but can't remember it

Although I was misquoted here I will answer this...

The biggest benefit of SOA is that you usually run near flat springs (if set up properly without too much lift). Flat springs have the best balance between up-travel and downtravel, and flex much more easily than springs with a lot of curvature.

So if you had 2 rigs of the same type with the same height (with all other things being equal - wheels, bl, etc.) but one was SOA and one SUA - then the SOA rig would have better (or at the very least smoother and more balanced) travel.
