coils AND leaves?

[j-top paj]

something ive never seen before??







is this a common thing?

[4bdan]

I've seen it before, however I have No idea why it's done?

[TheOtherLeft]

It's done for extra load carrying capacity. Does the same job as polyairs, but cheaper obviously.

[rockcrawler31]

I've seen this done with both coils and airbags. Typically done to carry a load. I like the idea with either coils or airbags, because you can have easily adjustable spring rates by changing coils or air pressure. before changing to full coils I was toying with having a 3 or 4 leaf rear pack with longer main and wraps and extended shacklesthat effectively only located the axle, and airbags to carry the weight. Mainly because i was sick of having to change leaf packs to go from flex queen to travelling.

I seen this on a hilux years ago and they where there as the main load bearing spring the leaf springs only located the diff housing. it had a good deal of flex with the setup too.That's the time i have seen it.

I had a similar setup in my Hilux by Outback Suspension. It used coils for lift so that the vehicle sat about two inches higher than the leaves if you removed the rear shackle pins. The front had two leaves per side and the rear had three. As HANCOCK said, the leaves pretty much only located the axle. It was really good and had good flex. It only rode on the coils unless it really loaded up and then the leaves kicked in. I would definitely reccommend it as a second to a full coil conversion.

I ran it on my lux. Had flexy rear leaves with drop shackles for off road then Jacked it up and fitted the coils to take load. Had best of both worlds and cheap.

mate had it on his BJ73 worked really well. Distributes load on the chassis as well.... Nissan Owners take note

i saw this on a hilux ot long ago but was thinking if you only had a 2 or 3 leaf pack with a coil wouldn't you get bad axle wrap?

[Dane]

I would have thought so based on what I have read. The bloke I bought mine from had a 308 in it before I bought it and he had blown his third gearbox - by his own admission he had flogged it. I put a Commo V6 in it and gave it a bit and all was fine. Good vehicle.

I'm amazed that outback suspension still operates. Such a dumb idea.

High spring rate for load carrying but with poor axle location

every year, outback turn up at Wandin with their 60 series with even more stuff stuck on it, like it's a cool idea to have a dangerously overloaded car so long as the springs hold it up.

Sadly there's no photos of their hideous junk on their website. The front end of the hiluxes they do are especially amusing.

Just my opinion of course.

You're right. I've never seen the people you're talking about but there's definately the chance of axle wrap when using only a couple of leaves and the coil helpers. There's definately a middle ground and sometimes you have to make the call and say that if your trucks for hard play then chances are it's not going to be suitable for hard travel.

[rockcrawler31]

Traveling on corrugated roads is a lot more comfortable with OUTBACK SUSPENSION because the leaf springs are being controlled by a frictionless coil spring, where as leaf springs have harmonic vibrations at different pitches depending on the length and spring rate of each individual leaf, thus causing axle hop. As mentioned, with the coil as a dampner on the leaf pack, speed and comfort are greatly improved. On the front end the same of course happens, also handling is improved to the point where the stabilizing bar may be removed if so desired.

Just looked at their website. What a crap site! It must have been designed by a 4 year old. They can't spell "urathane" properly and some pics would be good.

Not to mention i have never heard so much rubbish as in the above statement.

Last time i checked axle hop was a phenomenon caused by geometry and poor damping under hard acceleration. Not to mention that leaves usually have better self damping qualities than coils due to interleaf friction. And saying that damping is improved the point where the sway bar can be removed????? What a top idea that is.

A bloke I know had them on his Hilux dualcab.

Ive seen it a bit, but thats the first time Ive seen coils and leaves on the front axle though

[Gwagensteve]

coil springs are well known for their dampening qualities.

I don't like slamming businesses but really, the claims they make for jamming coils into a leaf car are just so wrong I can't let it go.

apparently there's nothing that can't be fixed by jamming coils in there

Steve.

got any literature that explains how that works? I'm not saying you're wrong, just that i've always heard that leaves are best at self damping and i can't see how a coil can self dampen? I'd like to know how that works.

Steve had his sarcastic pants on.

Oh....

internets sarcasm fail

[Willy Hilux]

If you are concerned about axle wrap, which will happen. All you need to do is fit a ladder bar. Problem solved!
