Suspension Lift

[Toybox]

8mm will be fine. Just take care when bending the plates... Otherwise you could use straight plates and spacers...

If you're planning on going with shackles that long then I would definately cross brace the shackles. In front be careful that under compression the shackle does not bind on the chassis rail...

[Hi-Hilux]

Straght plates and spacers? Are you talking for the front ones with the bends?
Cross brace...for the rear? Explain to me nice and slow please....soos die leeu loop, stap vir stap

[Hi-Hilux]

Het gou op Autocad geteken, dis wat my plan is.

[Toybox]

The front one with the bends. you can either bend the plates as per the original or you can use straight plates with spacers on the spring end to take up the width difference.

At the length's you're talking about I would cross brace both the front and rear. It should help keep the vehicle more stable and lessens the stress on the shackles...

[Hi-Hilux]

Something like this?

[Toybox]

Exactly...

[teerpaaltrapper]

Die langer scakles werk baie goed ek het dit ook gedoen maar dan moet die propshalfts ook bietjie langer gemaak word veral die voorste een ander wear die splines vinnig uit want dit werk op minder.

[Toybox]

I meant to add, be careful of too long a shackle. AFAIK the ideal shackle angle is about 45 degrees. Too gratan agel and the spring rate starts to get very stiff ( and no droop ), too small an angle and the spring rate becomes very soft ( and no compression ).

There's also one other little catch, and that's the castor angle of the front axle. If the shackles are too long you'll tilt the axle 'back' and run the risk of death wobble, and other odd steering issues....

Have any of you guys fitted the scissor shackles. The yanks use them with great articulation results.

I will use the same as Mr B, he uses 143mm in front and dont think that will cause problems? Bretton any problems with your front with your 143mm shackle?
Its only the rear that is going to be 190mm

[Gunta]

oops the pics did not come through. I have a pdf file with a large catalogue for all this stuff that you guys might find interesting. Any idea how I can load it so you can see it. The pdf is 2.7megs

[Mr_B]

No probs Trevor, my ext shackles are industry std. 150mm jobbies!

[Toybox]

Scissor shackles are fine for a offroad only vehicle, and even then I've heard horrible stories of them 'unloading' on side slopes.

One option is it use the revolver part of the shackle without the 'scissor' section, this allows the spring to twist under articulation. IIRC Pype and Syron Conversions have scissor shackles fitted...

[Hi-Hilux]

If i can remember correctly uncle Family Dog also have 190mm shackles in the rear done by Bennie?

[Gunta]

Those revolving shackles look neat,I have not seen them over here unless someone has imported them. And as far as i am aware they don't affect normal driving use.

[Hi-Hilux]

Mr B you said 143mm now you say 150mm....do you want me to take you to court for that 7mm?

[Gunta]

Check out this website. They have everything on suspensions and more. You can download there catalogue from the website. Very interesting!!!

Johnathan, Adding between 50 & 80mm to the shackle length should have no significant affect on either the angle that the shackle hangs, nor the kingpin inclination of the front axle. I doubt it will even make as much as a ½° difference in the castor. I would imagine that more pressing issues would be the need to fit an adjustable torque rod and lengthen the front propshaft. The rear should be OK because the swing arcs are similar, but the front swing arcs are opposing, requiring more travel on the slip joint splines.

I just knew I would have to go dig the photos out sooner or later! ;)

The shackles measure from top to bottom 240mm, while the actual distance between the bolts is 165mm. I can also adjust them one notch higher or one notch lower, if desired.

F_D I like the mounting options(extra holes)... they look very lekker indeed!

[Hi-Hilux]

Dankie oom Eric

[Family_Dog]

Dis 'n groot plesier, Neef!

Sien dis wat ek hou van die forum, ons is soos family, ooms en neefs

[krazy_kameleon]

Hi FD,

what metal did you make your adjustable drop shackels out of - they are very cool, would like to make some up for myself

[Family_Dog]

Richard, as far as I remember they are made form normal mild steel, 8mm thick. They were made up by a shop in Pretoria, I don't know which shop though. They were fitted by Bennie during the time that Bulldog was in Pretoria for a Dyno tune.

Oom Erick die afmeetings se oom is 240mm en 165mm tussen boete,het oom voor en agter eweveel gelig? Of agter meer as voor?En moes oom enige veranderings maak aan oom se propsharft voor of nie?

[Family_Dog]

Frans, Bulldog het 'n volle OME suspension in, maar vir een of ander rede die voorkant het altyd hoer gelyk as agter. Die nuwe shackles het dit net mooi gebalanseer, nou le hy gelyk.

Vir peace of mind, het ek die voorste propshaft laat extend, Johan by Propshaft Centre het gese dit is 'n moet na enige suspension lift.
