Outer Limits 4x4 Board

Hi all,

I'm looking at a h260 for my buggy.

how much heavier are they then a h233?

I have read that the full floater is only drum brake - is it as easy as a set of discs and some cailper mounts to change this?

Is the drum diff (gu) narrower then the disc no float rear?

how do I tell a 34 or 37 spline diff apart?

Is the full float rear axle a constant section (spline at both ends) or does it have an intergrated drive flange?

I am aiming to buy one, then widen it buy 2-300mm, to match the front and will need new axles hence the questions.


cheers bru

the leafy's are narrower (easy fix with custom axles) bolt patten for the axles are different so i'm preety sure the calipers from a coily wont just bolt on but i have never had a good look.

You have PM

they weigh a ton just sold a gq one with an air locker in it.

buy an MQ one, then get the short side lengthened by using 2 long side axles. Cheap and off the shelf parts!

Cheers fellas.

Are the axles on the MQ one reversible? (flip 180 deg) Otherwise the axle will run backwards, increasing twist failure? Or can I gust buy a new axle off the shelf?

Some early GU's ZD30, TB45E, TD42T, TB48DE's manuals had the coil H260 rear diff.

Worth a look.

I just looked at the big rear at the wreckers, its off a wagon. Its not full float. Looked about 30mm wider then standard gu, but only threw the tape over quickly.

The pinions appears to be the weak point - looks the same as the standard one.

this is right the pinion is the same as the standard size gq' gu's

Just looking at the ARB locker site. It appears the full float is 34 spline and the semi float is 37 spline. I can get a disc brake semi float for $660 complete.

Pity pinion is small. I am leaning towards a stg gu to get it rego'd then buy this (or similar) when I can afford it, as it seems silly to throw money at new axles, brakes etc and still end up with a heavy diff:

A 7200 housing would feature the following:

3.5” Race housing with full truss (upper/lower/back)

Currie 9” 3rd member with spool

CNC 6 piston calipers

Coleman vented rotors or Tubeworks blade rotors

2.5” Race hub

40 300M Spline TCS wasted body axles

About $8300.00 USD.

Went up to Marks and measured the MQ one. 1470 wms to wms.
Cut and shut with another long side gives me 1870 + tyre 315 + extra 12mm (8 1/2" rims 4" backspace) = 2197.

Front setup on 4" backspace rims is 86" tyre bulge to tyre bulge = 2184mm. This number will increase slightly with suspension load (a arms parallel to ground)

Think this option is a winner!

Thanks Greg.

Now is the MQ 34 or 37 spline?

According to arb it is. According to arb the full floats are 34?

MQ should be 37 spline (we have 2 of them , 1 GQ and 2 GU - H260's) all are 37 spline. BUT when we got the last ARB the genius at ARB gave us a 34spline CUS he knew better!!!

the gu leaf full float H260 I have is 37 spline

well then thats sweet.

Who has an MQ housing and long side axle I can poach?

Would I be better off with a gu full float, cut / shut both sides with custom axles, or just run the MQ semi float? Is there a MQ full float?

full float will be stronger and either way your gonna have to change the drums to disk. the only disk optionout there is a GU semi float.

There is 8 styles of H260 AirLocker

1 MQ
2 GQ ( Disk RD71 Or Drum RD70)With or without Long Cross Shaft Block)
5 GU

H260 is 52kg with an ARB Air Locker installed

the centre only obviously? by god it feels alot heaviyer than 52kg!
