opinions please on shckle design

[hypo]

just wonderin if this will work coz i need 2 outboard the shackles 4 my GQ axle swap and dont want 2 weld a shackle mount under the frame as it will become a rock anchor.

i think with suffucient bracing it will b fine

CHASSIS

SHACKLE

SPRING

BUSHES

[chimpboy]

There is no problem with that layout provided the materials are strong enough.

I would add a crosspiece to the centre of each shackle, that's all.

[hypo]

was planing on bracing them like this

[hypo]

shackles will b 8mm thick and yeah something in the middle will help

[chimpboy]

Just relieving my own boredom here, ignore at will.

I tihnk with those angles you are gonna get a force trying to pull the shackle outward and upward at the bottom which is going to stress the bushes; not a problem but I'd be using hard plastic, not rubber, so that this can't happen.

The reason I suggested a centre brace is that without something between the two sides of the shackle, they are prone to twisting; that is, one side of the shackle swings forward or backward MORE than the other side, allowing the spring to deform and generally phucking things up.

Yep definatly weeker at the bends x brace it like mentioned B4 and also on the side but not as much as your last pic.

[4sum4]

Have you thought about cutting a perch in the diff pumkin?

this dude is lookin at doin somethin similar
thought it might help

[NICK]

wont work you need to move the bend down lower.

[NICK]

i think on conpression they will rub the chassis here, thats why i think you need to move the bend down lower.

standard shackles will rub so i think these will to with the amount of travel that you have.

[customhilux]

keep the same idea, use flat bar, inside the shackle makin like a "H" channel

and u can also add some bracing to the sides just to help.

i think u can't get any stronger than that.

i had a sweet pic to but i can't add it for some reason, this keeps comin up

The Extension bmp is not allowed

Ben, just make a new set of pivots and mount them below the chassis and offset to suit them you can use "std" shackles the same way we did on adrians front end, it certainly doesnt limit flex on his. Plus in qld it is legal to weld mounts to the chassis but illegal'ish to run longer shackles go figure.

That's tomorrow's job for me. I think hypo wants long shackles though.

... almost.

It's legal to affix mounting blocks to the chassis but it's not legal to modify the chassis, which would probably include welding all over it.

I'm not saying you shouldn't do it though.

i think he wants to run them through the chassis so he dosent get to much lift out of it....

although u could just outboard an move down like 1mad said but run a shorter shackle

How much more work would it be to go coil conversion?

After all the brackets are already on the diff, and would save making anti wrap bar.

There's coil hiluxs getting around, so it should be able to get eng certificate?

[customhilux]

ok here's my idea,

just use the same flat bar from doin the shackles,

[NICK]

what about something like this ben?

Ben has had the brackets cut off the diffs long ago, so hed have to make up new brackets, plus, his leaf setup works really well when i have seen it in action

[totto]

I would go for a reinforcement bracket like this. it would reduce torsion stress on the frame and prevent premature bushing wearout in the frame-to-shackle bushing.
Bolt or weld on - a matter of local laws and what's suitable for the builder.
Don't get hung up on design and dimensions - it would have to be customized to the application.
(Idea taken from other "frame-offset-to-spring"-solutions, even factory ones)

[berazafi]

some mq patrols use the ofset style go to a wreckers pick one up and copy it with the length and width you need

[hypo]

wont work you need to move the bend down lower.

yes i know this i should have said that the drawing is not 2 scale thanx anyway....

1Mad,

i dont wanna do it that as i am happy with the ways things r with the current shackle length, it flexes mad, rides nice and smooth and gives nice smooth opreation. plus even using a standard shackle under the frame it will hang lower than my longer jobbies..

totto,

the only prob with doing it this way is that i wont b able 2 have a straight side,

nick,

i thought about just spacin it like that but it means custom bolts and stuff and i think the bolts will bend easily

[totto]

The bracket could of course be fabricated to fit curved frame rails too, but also it would mean a lot more work. It's a matter of how much work one whould put into it.

[hypo]

after much toying and thinking and brain racking i have decided 2 go with my original plan which is the sencond pic nick posted and just get some bolts made and get it under there and driving and if ihave probs ill worry bout it then.

once again thanx every12 4 the input....

[antt]

lol, nice filename

[hypo]

lol, nice filename

hahah i didnt c wot nick had saved it as until u mentioned it then DOH!!!!!!

[hypo]

actually i have made up my mind

ill use the original extened ones i have cut them and flip them so that the anlge isnt as much and run a thinner spacr 2 make up the difference..

its sorted ill get them done 2morra

thanx again people

[hypo]

well this is wot it turned out like and i farked up coz i dint take into account that the inside plate is already offset outwards but i think that by the time i remake the inside plate the angle will b 2 sharp and make it fairly weak

sorry 4 the quality its from my cam fone

booty-licious

[NICK]

YEAP, NEEDS A CROSS BRACE FOR SURE
