Rear suspension done

[lexulance]

[lexulance]

May need some lighter springs, but test was done with about 5l of fuel in the tank and no top of the deck also minus gear etc on back so will do some testing off road and loaded in the weekend

[mudslut]

Nice work man,looks tidy,what trailing arms have you used

[lexulance]

Hi, i have used pajero rear arms, and the springs are a chamberlains surf super lift

[KIWI_TERRANO]

I think your find the springs are sitting up the wrong way?

may have something to do with flex issus?!?

[Bolo]

yea they look upside down to me

[lexulance]

You would be lead to think that as was i but i have checked under my work mates surf and they are in correctly.
The flex issue is more to do with the shocks that are in there, they dont have a lot of travel, so im gona go see what autolign have to replace them

[KIWI_TERRANO]

Just had a wee lookat my surf,

The top is the fatter part of spring and the bottom is the skiiny end.

From what I learnt talking to 4wd shops etc springs only work one way round. It should flex like crazy even unloaded cause of up travel.

surf doenst have much down travel but it still has heaps of flex cause of up travel

[lexulance]

Ok ,will turn them up the other way and see if makes any difference, if i disconnect the shocks it does flex up very well in that same spring orientation tho?

[KIWI_TERRANO]

just trying to upload a photo of mine but it doesnt want to play cricket with me sorry.

[tomsoffroad]

What difference would it make if the spring were upside down?

[lexulance]

That is a good point, will it make that bigger difference

[KIWI_TERRANO]

Isnt the spring wound in a prosist (need spell check) way to make the spring comprise etc to match the vehicle, if it was upside down would it not put everything up shit creek?

Like running leafs upside down it wont work properly I got told anyway

[lexulance]

I honestly dont know, all i can tell you is that without the shocks connected it does seem good in the flex department

[suzolla]

From what I learnt talking to 4wd shops etc springs only work one way round.

you have got to be kidding. Classic.

I think you should find another 4wd shop, a coil spring has no idea which way up it is so it will make no difference which way up it is except how it locates in the spring perches.

Sounds like shocks are too short, when you get longer ones just make sure they do not bottom out on full compression, to check take the springs out and let it rest on the bump stops.

Also your radius arms will be restricting flex.

Pwnt

[lexulance]

Thanks for that, it makes me feel a bit better, didnt think it would have made any difference.
agree tho better shocks are difinately needed, the ones that are on it at the mo are just there as a mock up and to stop the springs falling out on maximum flex

[De-Ranged]

A coil spring is a linear spring or as good as there is some change of rate due to the smaller dia coils these are stiffer... which ever way you install it will not change that
Oh and KT leaf springs are different they are made of lots of springs that require the larger leaves to bend the shorter one's, put them up the other way and you only have one spring in the pack working why you get such good flex from leaf springs they all work in compression progessivly and only one leaf to resist drop

move your axle mount for your panhard up and you'll increase your roll center and the suspension will resist a bit more body roll
Looks to me like your coil springs are too heavy

Just to make my point about leaf springs here is a setup I did for a young lad $40 XD falcon springs and extended shackles $150

plus u bolts, u bolt plate, new bump stops new mounts at the fixed end, drive shaft extension...

leafs have good points but coils any day

[De-Ranged]

hmmm no I must be wrong.... I mean how much is a full set of suspension links, custom mounts for links and panhard worth oh and don't forget the extended drive shaft becouse you've pushed the axle back oh and the new bump stops or the springs
All so you can have less flex, but bragging rights....
Coils are linear that means there are real issues getting more down travel than up...
Don't coil your truck Jess it will wreak it

Sorry Lexulance for the hi-jack its a long standing argument
he has a SAS'd Mu on leaves that flex's almost as well as the orange surf and still drives really well onroad

I was reading back through your posts if your going to get new shocks talk to your certifier some of them will allow you to run spring location cones, use a tab to lock the spring down on the axle and then some thing like this

some certifiers allow this some don't...

Cheers Reece

[wopass]

they work way better upside down Oww..they push the axle down to get more traction instead of lifting the body up in the air...

[turoa]

:lol: hmmm no I must be wrong.... I mean how much is a full set of suspension links, custom mounts for links and panhard worth oh and don't forget the extended drive shaft becouse you've pushed the axle back

Why would you have to push the axle back? it can stay in the same place

Btw, I put a 4 link in the back of my hilux for less that what it would cost to replace the broken leaf (links.... zip zero nada) and it performed way better offroad. Can calculate and tune squat easily and changing the spring rate consists of buying new coils

new bumpstops - umm you need these in leaves aswell?
buying leaves - same cost as buying a set of coils
Shocks - well you need those for both

Im not sure what you're getting at by saying soils are linear? Do you mean linear spring rate? because thats incorrect given that the more you compress a spring the more force it has pushing back.

Getting down travel is no problem, it consists of either capturing the spring top and bottom (which forces the axle to articulate and alllows it to be stable) or of course you could try buying the correct, long length coils!

Ive tried leafs and found that they are complete and utter shit. Yes they can flex great (I can upload a pic showing this) but man they're uncomfortable (not to mention not being able to handle the bumps)! If they were so epic then why aren't all of a) the racers running them (ie koh, offroad racing, xrra etc) b) anyone that doesnt take half a million years to drive 100m

[turoa]

not to mention the fact that you can have an approach/departure angle of over 90deg

[lexulance]

No worries De-ranged, that looks kind of dangerous, i know if you have calculated the length of the cone extension properly the spring wont or cant fall out but eeh
Have re done my flex up in the driveway with the shocks disconnected and the springs dont fall out but only got bout an extra inch of downward travel, so total travel is now about 10-12 inches
No big deal though from the start i only really wanted it to ride a bit nicer which i think once the softer shocks are sorted ill achieve aswell as a small lift

[De-Ranged]

your shocks still limit your axle drop but will allow a bit more drop travel.... personally I'm not a big fan of it as I want the weight of the wheel and axle tied to the truck better

Tu's point about correct shock placement is better..... if you can mount your shock the wheel side of the spring, under articulation the compressed spring will help to push the dropped side down some be carefull with doing this as the further in your springs are from the wheel the more the truck is going to want to tip... your axle becomes a lever reducing the force the wheel needs to compress your spring..... will make the truck feel tippy

I'd still move your axle mount for the panhard up this will raise your roll center and improve its resistance to body roll

Tu's I've reply'd to your comments but I've done it in another thread save hyjacking this one
Go here.....

Cheers Reece
