Outer Limits 4x4 Board

This is ganna sound really stupid, but what is the name of the things that go onto the end of your axels and lower the wheel so the diff is higher off the ground, you can use either chain or gears and i know a guy in Geelong used to make em but i don't think anyone else does.

if that doesn't help i'll try again

Is it a tyre????

portal hubs

portal axle boxes unimogs have them

no it's like a um the axel goes onto a gear instead of the wheel, hub what eva and then there a 2 more gears that go lower with or without reduction and then the lower gear goes out to the wheel and spins it. you could easily get the center of the wheel 3" lower then the axel center and i think a little off set because the wheels are moved out alittle.

does that help

why dont you get your licence first.

stuff you 2 weeks

They already told you.

yeah they are called portals

mogs come with them standard and the bolt ons were for rangies

Apparently this is not correct, but he will explain it again

it's the portal axles thanx for that.

does anyone know if anyone makes the portals to go onto your 4bi axles

What car?

Maxi Drive make kits to go on rover axles
About $14k

Search the rover section.

Dave.

like nissan's toyota's etc

nope they dont and the cost of them it would be much cheaper to buy some mog axles and convert them for your rig,


but the main question is why ?????

do you need them ??

or they just for looks when ramping maccas bins and shopping trolleys

yeh i make em

i use bicycle gears as i find it easier to work with

For you Gilli Pie a tyre will be the only thing that raises you diff from the ground!

allready running 33's and my dad thinking of making them for his nissan and others if he can make em relativly cheap. only thoughts at the moment though, nothing concrete. i'm just doing some research for him.

You dont even know the name, but yet your conidering making them?

However you do it it will not be cheap. If you have access to all machining equipment and can do it yourself it may be possible, if not then good luck on $$$$.

There is only one person i know of that has made a set.

Dave.

what drop do the mogs have anyway?

its not 3" is it?

Volvos are 5" or 6".

Mogs are similar - 6"?

Dave.

do a search on pirate they are talking bout some bolt on ones atm think the price was around 8k USD

dads a mechanical and electro engineer got a all the machinery at work. didn't know the name because we've only ever seen one picture of these in a 4wd mag and it didn't mention what they were

Look at the design of the Volvo and Unimog Portal Axles then.

Search both here and Pirate 4x4 for more info and pictures.

These are the Maxi Drive portals, made by Mal Storey in Queensland

Dave.

thanx for all that guys really helpful

Glen Dobbin made his own

Try Dobbin Engineering

would a chain drive require less engineering?

obviously it wouldnt be good at speed

but if its just for a buggy, perhaps it wouldnt matter

i have seen chain drive on rollers and other heavy equipment, and they dont look very technical at all, no where near as technical as that picture above.

send me your first set free of charge and i will give you sum feedback

If you could use the chain from a chain drive tcase and machine up a couple of new drive gears for it, it may be a possibility. Should be strong enough, and the speed shouldn't worry it too much. Only minor problem would be keeping everything cool, may need a small electric pump wired up to circ oil to a oil cooler.

Don't know how much chains are out of other tcases but the ones in the rover tcases are worth $1500 ish secondhand last time I priced one.

Even better ask this question on pirate and make sure you mention you are new!
