What are parabolic springs?

leaf springs that are thicker in the middle and taper down the be thinner at the ends. also the leafs usually only touch at the ends, with a block between each leaf in the middle(some claim this increases longevity due to less wear from friction... i say that a load of ...

The following is the content of some emails I recieved with regards to parabolics. I've got a forty and im putting parabolic 60 rears in the front of mine with a shackle reversal soon. If you find somewhere better and/or cheaper then post it up....

The ea rliest model Landcruiser we have ...

Its on Ebay for around 15K

So... I was cruising round fourby's website looking at 33's and saw the radial claw comes in 33/12.5/15... cool...

but then i saw that it also comes in 33/15.5/15!!! As a light truck tyre. These have a 3 ply sidewall and 6 ply tread.

Is this better for a 4x4??

Wood

Guys,

Im aware that the 3 ...

Are they the fourby's rims Dave??

Had the 37s fitted and balanced to 10" rims about 6 weeks ago!

Takes less than a second to accidently knock a weight off a wheel. Specially if your underneath doing wheel alignments etc...

I've seen this happen on several different cruisers and death wobbles were always solved by getting wheels ...

Its wearing 37's??

When was the last time you had the balancing checked on the wheels....

If you reckon there's nothing loose in the steering then thats the next thing i would be checking. Especially with wheels that size...

Wood

Thanks heaps for the info guys.

I've passed on the details of both the powerjection and the holley avenger EFI system to my local performance shop and their chasing down prices for me. I'll post up and update when i've got them.

Cheers,

Woody

Guys,

The powerjection seems like just the thing I was chasing. Where did you guys order them from?? Is it gonna be better to order from the US or are there some places in Aus that stock/sell them??

I've done some googling but not found anything concrete...

Woody

Guys n gals,

Im currently running a carby fed 350 chev in my 40 and im looking at converting it to efi for some better drivability offroad.

Im hoping to keep things fairly simple so Im looking at an efi throttle body which will just sit in place of the holley carby I currently have. Something ...

I've pulled mine apart a couple of times but I'm a mechanic so its not too much hassle for me.

If you dont want to get to tricky, pull the dash cluster out, take out all the screws which secure the fascia to the cluster body then spray the crap out of the cogs with wd40 or something similar ...

oh thats handy! theres a couple second hand systems floating round on ebay luckily.

well ive got the 350! just gotta put the money through and wait for delivery, then its rebuild time!
i priced up EVERYTHING i could possibly need including stage 2 cam, water pumps, mechanical fuel pumps, forged ...

I'd be looking at answering a few of the questions mentioned here before spending money...

Wood

Whatever you get organised Mike, make sure you let me and Andrew know before you do anything as this is something all three of us are looking to do...

Woody

Jeez.... Wheres the bezel police when you need them... !!!!

Wood

To the best of my knowledge, (and i'm in the middle of my research like you), I think the 75 series front springs are the longest ones we can use. This will also give wheelbase extension depending on which way round you use them.

My current plan is to cut off the stock suspension from the chassis ...

Guys,

After seeing one of these in the flesh today, I've realised I need to source a set of 35's and stick them on my forty.

I'm having problems finding a 'size availability' chart to see what size options I have. Does anybody have a link??

Also, as stated above, their obviously a little hard ...

As I may have mentioned previously, I just did this to mine. It was safe to lever the shaft out far enough to put a new O-ring on. Im a mechanic anyway so just got my o-ring off the shelf at work. I'd suggest putting some sealant of some sort on the shaft/o-ring when you slot it back in though as ...

Guys,

Well, somethings let go in my transfer case and i've started to have regular little pools of oil gathering underneath it. Its leaking from the area pictured below:

Where'd you get the parabolic spring kit from???

Wood

cheers guys. Forgot about the solid lines for the brake booster. That might be a pain in the ass.

Looking to do the Qld 2+2. ie 2" bodylift and 2" suspension. This keeps me legal and high enough to fit some 35's with plenty of space to spare. (most peoe will now say " but 35's aren't legal" which ...

Try the search function mate, its been talked about on here lots recently. ..........

Try it yourself. Plug in 'bodylift' then any other combination of 40 or fj40 etc. Not everyone has time and motivation to troll through posts from 2006.

I'm looking for current information and opinions from ...

Guys,

Just about to do a 2" bodylift on the shorty 40 and I'm just posting to see if anyone else out there has done it before and whether there's any advice or opinions that can be shared??

Any help appreciated...

Woody

Yeah,

The thing that interested me most was the shackle reversal kit. Combine it with a set of 45 series trayback rear springs (Their really long) and the front of the 40 flexes like crazy.

just gotta figure out what to put on the rear. Thinking the same springs with drop shackles...

I've ...

Something like this you mean???

I have exactly the same issue as you and i've been informed by the good chaps at 'The Carby Centre' in Townsville that the 600 I'm running can be midified to suit the steep climbs we do. Apparently, its a fairly common mod and not that complicated to do.

Woody

Could be... Walking across the road to put the deposit down tomorrow...

Isnt it strange that you can look all over oz for a car and then, just by accident, the one you want pops up less than 100m from your doorstep....

Someone else recomended BIPS as well. I'll give him a shot.

Cheers,

Wood

All,

Just about to pick up my V8 40 shorty and I need to get a RWC done so I can change it into my name. Im up in sunny Townsville and at the moment, aside from your regular joe blow mechanic's, I cant find anyone decent to do it for me.

So, is there any guys up here that are '4x4 sympathetic ...
