What's the longest rear lux spring anyone has used, and how did they work??? any photos????

Cheers

I have no pics and not sure who has used them (if anyone even), but i have heard that XD Falcon ute springs are the go......about 59" from memory.

i think hypo had some 77" ones

63" rings a bell to me same as the chevys every one uses in the states i think

Sounds about right Tim. Werent they Falcon packs ?

So is the longer springs worth the extra effort compared to IFS rears. How much extra travel would you get.

I have Explorer rears on mine (56.5") same as all falcon/ fairlane except centre pin location. They are thick and hard steel so flex won't be brilliant until packs are customised and extended shackle used.
So if u r going to get new mains fabbed up and move ur mounts might as well get them custom made to 63" ( or any other length to suit- but the engineers prefer springs substituted from another vehicle- on paper).

yeah that was just a guess i just knew that they were long

My rear packs are custom made, they have

7 leaves all 7mm think
main leaf is 1500mm or 59inch long

They flex very well (about 24 inches with shocks that are to short n one set of clamps still on them) and ride very well just don`t try to carry any wieght on them as it becomes like a boat on the ocean

Thanks for the info guys,
Guts how far forward did you move the hanger and how long are your shackles. I know this will differ depending on what spring I use just after a rough idea, any pic's ????

so that would be about 10" more than using IFS rears, well worth the effort and a little extra expense.
Might do a hunt around the wrecking yards and see whats about.

Cheers Guys

mine are customised 63" (now 64") Chevys, with a custom drop shackle setup, Flex is awesome, not sure on figures but. Still have all spring clamps in place. I also have 52" custom ones in front. which use all but 1.5 - 2" of travel in 99036 shocks. they also have all clamps in place.

Go to http://www.snakeracing.com.au/media/articles/guts.html then read the rear suspension section, all your questions should be answered including the shackels which are still hung from the standard hanger on the rails. Just to add to how it still drives with these rear springs in. With the normal wieght I carry on the back (tool box full and spare wheel) it drives great and handles well for a 4x4. Its only when extra wieght is added that its crap.

Falcon springs are the way to go,yes,just like HYPO's,just bear in mind that they are 'wider' too,so you'll have to fab up some wider hangers.
