Outer Limits 4x4 Board

Hi guys, after deciding to draw the line on the fact that pushing too much more outa the front on mine i may break or creat dramas for daily, ive decided to start persuing the rear end flex.

Got a set of stock ifs rears for 50 bucks, wich i considerd a good buy, found a set of superior ext. shackles in good nick and already have the correct length ranchos and bracketry for the hight and inverted rear shock setup. all i gottah do is get time..

After reading all the bibles here i have gatherd most info needed, however i just wanted to no, if i remove the two load carriers from the pack and replace them with a single 2 inch lifted mid range leaf to regain hight-ish, and maybe cut the load carriers down to act as small lift blocks.

Does this sound like a reasonable theory, i no its all trial and error, learnt about that from the front

pics of pack and single 2 inch leaf.



cheers guys, Chris

hay champ i done exactly what you are doing to my old lux everthing you said is good but the sping u wana put in will need to be cut shorter on each end to fit in the pack right on the bottom. and the shackels wont work you need them 200mm eye to eye not 180 u wouldnt think it makes that much difference but it does. that help you?

Aren't superior shackles 200mm

ok cheers m8, ok ill have to do that with that spring, but on the same token ill round all the ends of the leafs to aid abit in the twisting of them. So 200mm eye eye, looks like i will have to see bubs for them shackles. Ah one problem though its a daily driver and these bullshit boat anchor shackles hanging out the back will be pretty eye catching to boys in blue, true??

Chris

just move ya hangers,

na think the superiour are 2 inch lifted witch =180mm but check to see anyway could be wrong wouldnt be the first time. no i dont think 2cm/20mm will make any difference to the pigs and you can design them how ever pretty you want lol, richo made mine up if you wana ask him if you give me yur email i can send you some pics of my old rear it looks sexy lol

okies man, thats true. Im thinking of chatting to my mates engineer about the whole setup being plated.Pm sent with email bloke.

Don't think in QLd extended shackles can be certified legal

also guys, in regards to shackle lengths.. why is it that the 20mm diference between say sup/snake shackle vs a 200mm eye eye cutom job is so cruisial? Ive been told that snake/sup shackles wont work? Can someone please explain this to me and my young idiotic brain?

I took those carryer leaves out of my ifs lux which has snake shackles and it started to wrap pretty quick ie bout 2months and probably only one trip off road but i am running turbo and gas so theres a fair bit more power there just something to watch out for

ok thanks, i ended up coming up with this, the 3 top ifs leafs, followed below by a 2 inch single spring cut to suit wich lifted them a bit then the long load bearer in the bottom.. i can see myself pullin them in and out to get them right but i did it for the front so the rear will just have to be the same... you can see how muchg the 2 inch spring (rusty one) lifted it cuz that u bracket toward the rear of the spring is unable to have the bolt put through the top of it.

finalresult.

that looks right champ but why u still got the load leaf in??? and the ifs springs are longer if you got the big ones and screw up your shackel angle because of this. if yur real worried bout pigs u could cut off yur rear shackel mounts and mve them back till u get the right shackel angle then re weld it.

The shorter of the 2 load leafs are out. Time will tell if they need less or more leaves and once the weight of the utes on it you'll be able to get that bolt through

just wondering:- IFS rears--

total length and also front to centerpin measurments plz

if this gets a couple more updates, it could be bible worthy.

keep ya standard length shackles dude and move ya hangers to get the right angle. CMON!

it will become rather pointless keeping my standard shackles. Im pretty sure im over it, im just gonna weld everything i need to and run the shackles if i get defected she comes off the road.

thats the way my way of thinking is u dont lose points for defects so whos realy worried about $70 fine thats what i got neway then got it cleared with them still on.

The major reason the IFS spring conversion works is due to the shackle length. Have a look at how well the rear end of a standard IFS hilux works, if you move the mount and use a standard shackle this is all you will be producing. With the 200mm centre to centre you get pretty clsoe to a 45* shackle angle.

oh ok, i would've thought that cos they are a longer, flatter spring, that that is what made them flex like a mofo.

so using the standard length shackle on the 45 with the ifs rears doesn't produce nice flex? that isn't what i wanted to hear...

What he's saying is that it isn't JUST the IFS rear spring providing the additional travel. Its the shackle angle changing resulting in a longer arc of travel allowing the spring to drop out further.

thats exactly right guys. same with droppie setup, you can have the big long springs ladder bar the worx and shocks done and run a standard shackle and i wont do sh*t. The majority of most flex is how well you use the angle of the shackle. People always ask me how i get my front end to do what it does on standard shackle and shock mount... its all in shock lenght and use of shackle angles..

On the issue of getting the shackles engineered, it depends how cocky the engineer is and how he puts them on the report, i had one report where they where written as longer replacement shackles instead of extended.

Just my 2 c worth

Also know of this trick with air bags in low lux's and so on don't call them bags call them air springs and they put them through don't know if it's true or not

yea, i did say to move the hangers so that the shackle angle was right (45degrees)

The longer shackle also gives the spring greater free movment. I wish I had some better pics of it working.



Tech:

To fit IFS springs which have a larger OD bush and are sleaved with a smaller bolt. Remove the factory bush and goto supercheep and buy the below bush. This will allow you to reuse a factory solid axle spring mount pin.



Again I never took any photos of the rear spring setup on my last hilux but. I ran modified stock IFS rears. I used the top 3 leafs, and 1 spring from an old front pack on the bottom. So a total of 4 leaf's I never ran a track bar.

so would i be correct in saying if i move my shackle mounts forward on the rear of my IFS lux it would have the same effect

yeh i would say so, cheers for the pics bubs m8 appreciate your help. M8 pm is sent too... cheers, any chance of getting this thread put into bible cuz this is really good for ppl who dont no about it, one of the more user freindly threads i think.. cheers, ill pm ruff.

im in the process of doing the conversion and im only useing 3 main leaves and 1 load leaf the very big one of the pack and 200 eye to eye shackles but i had to put 2" lift bolcks to get the hieght back and i think with this converion the is no way of not doing a track bar. the spring pack is just to soft!

the last set up i had had rears opened up with only 5 leaves and i rapped them up in 1 comp. that was without a track bar.

the only thing left for me is to mount the shocks and get my trackbar of richo

cheers hope this helps any

I have standard rears with a 5 leaf custom pack longer shackles and a track bar, which seem to flex good.
Up travel is limited by the tyres rubbing the chassis.
Would probaly look at doing falcon rears next time, as 200 eye to eye shackles and IFS springs stuck out a bit for the cops to see.
They did have good down travel thou

Hey Chris

Here is a few pix of how my IFS rear works
its just a standard 2 lifted pack,
bubs shackles,
Inverted rear shocks.
the front has 3 inch lifted parabolics
shock hoops
rancho 9000 shocks all round
running 36's
