40 series flex.

[Sam T]

Would like to see the amount of flex that people are getting from various aftermarket leafs and different set ups (SOA, reversed shackles).

Also, for those people who have done a coil conversion (three link & four link), what is it like on the road and how is the stability vs leafs?

Just getting some ideas before I start working on my 40, as I dont want to spend lots of $$$ on leafs then decide i want coils.


Thanks

Sam

80 series chassis is where its at not a shorty but heres myne anyway

[shorty_f0rty]

[TWISTY]

Mine.

Still sprung under, approx 4" lift.
1260mm (49.6") long front leafs (about 4.5" longer then std.)
1340mm (52.8") long rear leafs (about 7.8" longer then std.)
2" extended shackles
12" travel bilstein 5125s all round
High Clearance U-Bolt Plates
Rear diff back 5" from standard, front forward 1"

[loosecanon]

im interested in this aswell,

can i ask how hard is it to replace the springs if the break i.e. invert? i guess this is more directed to you twisty as your springs sound custom made, and if i can ask how much?

cheers

any idea's who makes custom long range tanks in brisbane??

[Narrowscopeofreality]

SUA, approx 2" above standard
-Front - new Dobinson leaves (mains +1), with flat factory springs (bottom 3)
- 1"extended shackles, relocated hangers
-Rear - new Dobinson leaves (mains +1) about 2" over standard length with flat factory springs (bottom 3)
- 2" extended shackles, relocated hangers
- 2" wheebase increase

Not sure exactly what you mean sorry mate with the breaking/inverting. Are you talking about your shackle inverting and then being wedged up against the chassis?

At the time my custom set of springs cost $1200 from Dobinsons Springs in Rockhampton.

[loosecanon]

hey twisty,

not so much the shack (but i guess that will happen too) but more the spring,
ive got a mate from melbourne who constantly kept bending the springs, (bending them up = inverting) well thats what i called it, but every time this happend it took weeks to get make a new one, and had to get it done somewhere out of town,

p.s. im in bundy, any problems with this???

cheers

inverting shackles is incorrect spring and/or shackle length. a quick fix is anti-inversion shackles but they don't fix the real issue.

[hotgemini]

Damn, all these epic flexing Brisbane-based 40 series are pretty damn inspiring.

I've got a mate who is losing the love for his 40 series after picking up a TD 80 series and it makes me sad.

Would you blokes be interested in a day out wheeling to show him the error of his ways?

For the sake of nominating a completely arbitrary date, how about the sat the 12th of march?

Thoughts on a destination? Glasshouse? Mt Mee?

As Shorty mentioend, he shouldnt be bending springs that easily. Something else must be wrong with his setup. I imagine any custom spring setup would have some wait to get replacements for if you did bend them.

Only way I can see the springs bending on my setup is the shackles hitting something hard then bending the springs. But I know they hang down low so try to drive accordingly.

You bastards, I'm working that day. Hmm, will consider taking the day off for it, and even if I don't I'll hassle my mates to go along.

[RAY185]

60 series rear springs, 2 leaves removed, flipped hangers, extended shackles.
40 series front springs, 2 leaves removed, extended shackles.

.... yea not sure what other problems he had with it, ive seen him do it twice now,

sorry to hi-jack, but im almost at suspension stage now and i wanna get it right first time, who would you recommend seeing in briz about suspension, i finaly found fourby's in brisbane and they were pretty help full,(mine is a buil from stratch so the whole set can be done,

[Tojo]

none of the setups shown are "off the shelf". They are all custom. I doubt you will find anyone in Brisbane or in Australia who will sell you what is shown in the above cars. You can do what twisty did and get custom springs made or just do what everyone else did and mix and match toyota leaves. But you won't buy a complete ready made bolt in kit that flexes like the ones shown.

my dirt cheap lotsa flex do it yourself 40 series suspension:
front springs - 75 series front leaves (main and second leaves) + some of your existing 40 leaves
rear springs - 60 series rear leaves (main and second leaves) + some of your 40 leaves. Flip your rear hangar
longer driveshafts to suite
longer brake lines
get the right length shocks (flex it up and measure collapsed and extended lengths)
longer shackles



There is more than enough info in this thread for anyone to do it themselves. When you get stuck post up and people will help you out with more advice as required.

[Sam T]

Thanks for all the pictures and info! I am thinking that I will stay with leafs as they give pretty good flex.

How have people increased their wheelbase, as my spring hanger is already at the back of the chassis rail?

the springs are longer. Your front diff will get pushed forwards and rear diff pushed backwards.

The spring hangar is offset. Have a look at it. If you remove it and flip it around the eye is now slightly further toward the rear of the car.

[Sam T]

What lift is required to run 33's and how high for 35's, assuming i extend the wheelbase ~5in


Also I will be going for a 350 chev at this stage with a 5 speed box and gear driven transfer.
What should I do to the diffs to handle the extra power?
If I were to go for a disc brake setup would it be easier/cheaper to go for a set of 80 series diffs?

[84sloth]

if ur sticking with leave's id put a ladder bar on it otherwise u would probably get to much axle wrap and chew out your pinion's

yea im happy to get springs made up, just good to get advice and parts from, any idea's who to see in briz?

[stock 4runner]

Maybe spring works at Bowen hills quoted me $85 per individual leaf for custom ones about two weeks ago to give you an idea on price

[Narrowscopeofreality]

Suspension Stuff at slacks creek.

Sam T- Unless you wanna go coils, i'd use 60 diffs not 80, that way you get the longer springs too. x2 on the ladder rack

And the 33/35's, it all depends on how much metal you're willing to cut out to fit the tyres, whether you want to sacrifice travel, ect ect. I can run 35 x 10.5 with only about 2" lift.

[croozy]

I have Dobinson's in mine (got them off Dave when he got his new ones) Plus I have extended shackles.
Not as much flex as twisty's but ok all the same. I still have to extend the rear stops to make that end work properly.
After owning these I would'nt go back to a set of off the shelf springs. They ride better & flex better, they have however
dropped a bit in the arse end but I'll reset them one day my self.

[plowy]

Hey guys heres my daily driver swb it sits on 35'' tyres with old 2nd hand stock 80 coils with long travel shocks
no sway bars and a xlink to allow the front end to flex.
The rear end is 80 series 4 link with panhard and at front ,80 arms flipped for ground clearance purposes only otherwise stock 80 set up.
On road driving it normal its like a stock 80, drive it wild/ hard and it bucks twist sways rolls and leans , fun for the driver -scary for the onlooker /passenger
It would be changed by just with fitting sway bars and changing the shocks im using, but all in all im happy with it as is
off road its great the suspension does all the work wich i wanted ,plus the coils give a comfy ride too ,i wanted it low wide n flexible and im happy with it

heres a few pics

[croozy]

Nice plowy. Man I'd love to coil mine

[Sam T]

Just roughly how much would you say to coil a 40?

If i were going to replace the diffs and leafs anyway, would it be worth going to coils?



Thanks for all the info, I wont be ready to do the work for a while yet but it gives me an idea of what parts to start looking for.

[Narrowscopeofreality]

If you can do a bit of welding/fabbing ect yourself, AFAIK all you'll need to buy are a pair of complete 80's diffs from the wreckers or from on here, they come up from time to time.

As a rough guide, my local wreckers were asking $800 for a pair of complete 60 diffs.

But ask Plowy, something tells me he's probably got a better idea

[Tojo]

you'd be better off getting hold of a complete rolling chassis and that way you can get all of the links, radius arms, coil mounts, steering etc. It will be a lot easier to install and a lot easier to engineer using all factory gear.
