Outer Limits 4x4 Board

is there any web sites that give info on turing a fj40 from leaf spring to trailing arm and coil sprung??

Looks like not too many responses eddie

Im in the procress of converting my BJ40 to airbag suspension. I was going for coil, but decided it would be far more versatile for ride height and load adjustment to go air bag.

I have put the hardpan rod in the rear end already which has improved the ride substantially, even with the leaf springs still in place.

I'll go for a 4 point link rear end, and 3 point front end.

i'm thinking of commercialising the concept, but like you, can find no other information on coil or air bag. Plent of mody on leaf sprunf forties.

Shit its been one day! Give it time, Yota drivers are slow

Start here:

yes there is lots of crap in that thread but there is also a shit load of good info.


you wont find any straight out info for converting your rig, ie step by step, each person has thier own prefs and ideas etc.

id be going a 3 link rear and a 5 link front with air bags

check out http://www.calbah.com/calbah.htm they do coil and airbag conversion on 40s etc

still looking for ideas
any helpers?

I did an 18" air bag conversion on my 40 series and it is pretty cool.

Originally we were goin to remove the leaf springs altogether and go the way you're heading, but Queensland Transport, who had originally OK our propsal before starting the work turned around and said it couldn't be done when we double checked at chopping time!

So I ended up using longer 60 series leaf springs, with only 3 leaves, and then relocating the soring hangers forward (on back) and backwards (on front). This way as the approving officier agvised, to airbags are classed as an accessory to the suspesion, as the leave setup looks stock even though they wouldn't have a hope in hell of holding up the vehicle. Currently I get 6" variance in height before the spring and shackle are at full droop, and there is still another 5" in the bag in heght! I intend on fitting two sets of the Superior shackles to alleviate this, and a traction bar to the rear. All bags are independantly crontrolled.

Height adjustable in Queensland is great - I can look near stock if needs be.

Also check out CORE4x4 - the purple air sprung 40 series from Tuff Truck 2002

I think its www.core4x4.com.au

ive bought 80 serries diffs for mine as mounts are already done on diff end then . plus updates lots of other things as well .I plan on putting them in early next year so can probably tell you what not to do after that.I would be keen to here if any on has done this before as they could mabey give me some head start pointers too.

there are 2 blokes that have a baby shit brown shorty with a full coil conversion under it they call themselves TEAM WHISTLIN PIG have seen em in action in the ASCC held a cruiser park and it goes anywhere if not further then the GU's and the GQ's it got a turbo/intercooled 5 cylinder toyota donk under it i dont have any pics ...try askin AREA54 (troy) as hes filmed this rig plenty of times

Sell the pos and get another Hilux ya tosser

I rang calbah the other day first thing they said was "were not doing any suspension stuff atm ass we have got too many other things going on". fair enuff. then I asked about cost. Bloody hell! this bloke said I would be lookin at about 10K for coils on my cruiser or 15K for airbag's mind you that is for everything (coils/air bags,shocks,5 and 4 link, eng cert etc etc) and I will admit that if I had that much cash I could see myself doing it. but with my truck and my job...... well it is nice to dream.

Yep, I've got some pics, but I'm unable to pass on any info re the setup on this rig, except to say that it is very competitive.

Very very nice

Who needs coils or airbags or coilovers when good old fashioned leaves do the job

Do a full progress report as your project moves along

What worked, what didn't, pitfalls, parts, photos

Before and after stuff is cool but the in between stuff is where it is at

been in a few with coil & trailing arm,
i think that it would be better than the leaf spring's
was imperssed by them.

Ok ill get some photos of it as it sits now then ill do progress as well . I am getting it fully enginered and am going to wait till i have met with him before i start welding in new year

here they are . Im not just fitting diffs im going to try and get weight down to 1700kg all up kerb weight when finished .

the diffs are out of a 96 model and done 76,000 klm . The car weighs 2040 kg as in photo with two gas tanks full and 50 lt of fuel

Nice rim pretectors


Now stop posting pics and get back to WORK!!!!!!!!!!!!!!!!!!!!
MM G I think I might go and crack another Jimy can

I am also weighting till after issue 64 of 4wD monthly has come out to start work as it is featured in it and it may make it easyer to sell the things i am tacking off it . As i mentioned before im not starting anything till the enginer has had his input as he has been involved up to now .

I can post photos of details as it sits now if you like it has 75 serries troopy rear springs with single track bar and diff sitting 4" back, standard front with reverse shackel diff sitting 2" forward .
