Outer Limits 4x4 Board

how you going ppls, iv dont a search and couldnt finde what i was looking for..
i just want more flex without going to coils, what is a 3/4 elliptic rear. i looked in the bible thing, no pics so didnt make an sence to me ..

my beast is currently spoa on lux diffs with a 3 inch suspension lift,
ill be replacing the leafs with standard ones and getting longer travelling shocks as the guy i purcahsed the zook off removed the good ones and replaced it with a set of ranchos that have shit all travell. but what i want to know is what is the best set up with leafs, from your experiance what would you recomend,

thanks

flatter leaves (stockers?). Longer leaves (ruf? custom main leaf in rear?)
45ish degree shackle angle.
No whacky shackles imo. shocks the right length that are also mounted correctly to make use of full travel...

3/4 elliptical suspension uses a main leaf cut in half, and its fixed to the chassis where it was cut, lies flat against the chassis rail and the eye at the end attaches to the top of the shackle, thus allowing the shacke to drop away under droop, by acting as a "drop leaf" intsead of an extending/folding type "drop shackle"... google it.

All I can say is keep your Leaves as flat as possible for best ride quality, the more you inboard your shocks the crapper your ride is on the road but you shock will have more appeared travel. A well modified Sierra is one with eqaul flex big diff clearance lockers and crawler gears not one with big suspension lifts and major COG issues...

I cant be bothered writing and re-posting about 3/4 Elliptical but you can have a look at my pictures and stuff on the link below and see for yourself.

more flex means longer leaves... im running hilux front leaves all round and it flexes like mad and is still comfy on road.

rear up fron and mazda 808 in the rear and longer shackles both ends. all possible without chasis extensions or relocated mounts.

can it be engineered like that? anyone done it? i know my engineer wouldnt accept the way most guys do their RUF with the redrilled hanger and dummy shackle at the front...

just curious?

this would have to be 1 of the flexiest leaf set ups I know of in Oz !!!

i think this one wins for flex. without use of funky shackles

its funny because if i remeber correctly the flex was limited in that photo due to the brake lines being too short

and details on the beast above^^^^^^^^

Not discounting it as being a awesome rig and built up with a lot of thought, and not to say the leaves alone wouldn't flex great but it is running funky drop away shackles on the front....?

thanks for that man, it helped alot your pics and write up was good for the 3/4 Elliptical, but i need to know, how did you keep the leaf in place, by the looks of it, its held on by a U bolt (correct me if im wrong). should i weld it..


also when you say "more appeared travel" if i inboared shocks, do you mean it "LOOKS like" more travell or it "HAS" more travell.. sorry to sound stupid, but i thought having the shocks on an angle it will be harder for it to stretch due to gravity, if in standard form they will go straight down.. you get me

as for the rest of the mods, lockers, gearing ect..... its all soon to come, iv only had the car for 2 months.. lol

but thanks again

PM liam to be sure if you want

Its a YJ spring kit imported from the states, the "missing link" shackles give it the extra length needed to use the longer YJ jeep wrangler leaf springs.

Yes, teh buggy leaf is held on by 2 square section u-bolts around the chassis. Laying the shocks over means that their opperating ratio is less than 1:1 (i.e. when the springs compress 1 inch, the shocks may only compress .7 of an inch). Depending on valving this can cause the ride quality to suffer, as the shock may be vavled fine for a verticle (or factory position) application, but unable to work as effectivley when layed over as it is not traveling as far or as fast as it is designed too. But laying them over allows a longer shock to be packaged under the vehicle.

Yes as stated by a few other guys on here now they are held on buy U bolts around the chassis, it lets me adjust if I need to, or reverse what has been done with minimum work. Plus Welding all over the chassis isn't the best thing to do, and I wondered about the top flexing all the time if it was welded in cracking and falling of, that and if the top leaf is ever bent or wrecked i can replace it easily enough.

Sorry they way I came across with the shocks was a bit vague or hard to understand, but yes you can have alot more travel out of inboarding them as they wont be traveling as much as the rest of the suspension is, I have put RS9000X's on the rear now and turn them right up to the hard setting and for on the road to stop it wallowing around like a boat on the road and it has made a improvement as far as I can tell.

Anyone else running the YJ jeep leaf kit?? Im on the edge of ordering something like this and running it SPUA

Tim (redzook) ran the rocky road YJ kit I believe on his old (red) full bodied zook http://www.rocky-road.com/yjkit.html

Id probably be looking at the trail tough setup which you can get from either trail tough or lowrangeoffroad, i like the idea that its fully bolt on and reversable but would the benefits of the kit outweight the application of RUF, would it still operate really well in the sprung under setup? being in QLD it has to be able to get to the tracks still by being driven

This might be a good setup for fitting longer (flexier) springs but there's no way it is or could be made legal in QLD. Not even in SUA form.

You gotta remember this stuff is from the people who gave us Z-link steering Note pic.

Cant be run legally?? Even if its a bolt on kit not affecting anything??
The kit doesnt seem to touch anything to do with the steering and there is no welding involved.. just seemed like a good option...

Maybe im better off getting a new main leaf on all four corners made up instead at 2 inches of lift and the right spring rate and have it long enough to make the shackle sit for droop and retain the rest of the current 2 inch lifted pack and drop the bottom leaf... but thats probably going to cost a fair whack

Why would it not be legal in QLD? it only gives 2.5" of lift which you may be able to get down to 2" by using old springs. And in SPUA form you are not "altering the design of the suspension". Really it would be open to interpretation I think, depends on the person trying to sting you.

Getting new main leafs made up will probably be cheaper than the YJ kit. And I think the rocky road kit is the only feasable one to be anywhere near legal in QLD cause it has no drop shackles.

and the whole thing can be swapped back to standard 2 inch lifted springs if needed

I just assumed being a bolt on kit and in sprung under form would keep it rollover factor down and allow heaps of droop where its needed...

No z-link in that pic, that car has a full OTT steering setup, just with a bent draglink, probably to provide clearance to the chassis.

Layto....

Well rollover factor comes down to overall hight, centre of gravity and track width (and somewhat wheelbase). Being only 2.5inch lift then yeah it wouldn't be as tippy as some of the kits out there (mine for example lol)

in the sprung under method the car would sit at the same height i have it sitting at now i think...

just looking at the rear YJ spring this is the shackle angle with no weight on it



when lowered down and weighted up the shackle would sit more to a 45 degree angle yes?

Yeah it should be a pretty good shackle angle judging by that pic

therefore wouldnt really need the missing link setup on the rear...it would probably be overkill?? just the front...
