I would have thought the compressed spring would put such a force on the shackle pins to push them to their longest position in the elongated holes (the shackle would be in tension). This would effectively put the shackle back to standard length or longer therefore not explaining the problem at hand. Either way you need new shackles. Damo bought some the other day online and got them within days. His thread should be on the 1st or second page.

I don;t know what they would be off but they must be the wrong springs. Try ringing a different ARB and asking for ome rears to suit and ask what their product code is. Have your spring or shackle hangers been modified in any way?

ummm.....no. with the weight on the car the pins will assume the shortest length. put some good shackles in and see how it goes then.

the shackle is under compression nearly all the time. if you were to undo and take out one of your shackle bolts the end of the spring would move towards the front of the car.

found that out the fun way

Sorry, I thought the force of the spring trying to lengthen as its compressed would put it in tension when its locked back against the chassis like that.

hi all
i have just fitted a set of 4 2" EFS rear springs in my sierra WT and in the front i have the same problem. but with my 2" dobson springs they are half inch shorter than EFS in the main spring, so i changed the main spring out of the dobson spring into the EFS spring and now the shackle doesnt flip back
why i changed from dobson springs to EFS is EFS gives me another inch taller than the dobson.

I'd have kept the longer leafs and fixed the problem.the longer leafs would give a better ride and better droop on the diffs.

what condition are you stock shackles in? are there new bushes in the springs?

shackles are good and i got new bushes from bruce

its ruf right?
if so how did you do it?
whats the measurement from spring mount to shackle?
whats the measurement from eye to eye on your springs?

looks like your perfectly setup for that shorter leaf.
maybe a longer shackle is you only option to run that main leaf, as I doubt you will want to move a mount again.
Ps nice build tread mate

[alex]

the EFS spring size is 970mm centre eye to centre eye
and the dobson spring size is 940mm centre eye to centre eye.

wow thats heaps longer. I went ome and they were only 15mm longer thanthe rancho's they replaced.Either those dobsons are short or those efs are wicked long.

whats your thoughts on the two different shackel angles?

are they the same springs side to side?
if so maybe one side is sagged slightly
mounts maybe a bees dick different in lenghts

yes there are the same spring side to side.
i have two new sets of four rear EFS springs and now the dobson springs that i have tride and they all dont slove the problem?????
the length between the mounting holes is 970mm on both sides exact.

if thats the case then you zook must be heavier on one side usually the right

yes the right shackle is the one that sits more on an angel how do i make it level?

lol classic

I wouldn't worry,everyone here probably has that problem

[alex]

no probs thanx for the info

[Zook_Fan]

if your spring does invert though it is not like every one else. flex the car up in 'controlled conditions' to check the full range of the shackles angles to make sure it will not invert some time out the bush

[alex]

that is what ive done and it does invert only in the front thow and only with the EFS springs

[Zook_Fan]

if it doesnt invert anymore with the dobbo main than just let it be
