breakages will become more common, as comp trucks start to use long arm style rear links which tend to "plant" the tyres more in hard launches, this coupled to the use of 'stickies' or comp spec tyres place huge loads on the axles. Nissans have very 'brittle' axles and they tend to snap far too common. The axles are huge and will take far more power than alove_mud wrote:Yes they have been broken, but it takes some unholy abuse to do so even with largish rubber. 36's or less they are very very durable, 37's plus you need to think about your driving a bit and not just go at it like a rapped ape.
A friend rang Cheezy Racing today about having the H260 diff housing shaved.1MadEngineer wrote:breakages will become more common, as comp trucks start to use long arm style rear links which tend to "plant" the tyres more in hard launches, this coupled to the use of 'stickies' or comp spec tyres place huge loads on the axles.

H233, the housings can be shaved quite a lot and done properly can have the same if not slightly more clearance than a H233 housing.
7mm vs 50%+ increase in axle strength is a good deal IMO.segan1 wrote:A friend rang Cheezy Racing today about having the H260 diff housing shaved.1MadEngineer wrote:breakages will become more common, as comp trucks start to use long arm style rear links which tend to "plant" the tyres more in hard launches, this coupled to the use of 'stickies' or comp spec tyres place huge loads on the axles.

They said they can shave off 23mm which is still 7mm short of the H233 diff housing.
So 7mm less clearence than a H233 diff but on the up side a heap more strength.
Cheers

(we shave way more than most in our comp diffs, we plug weld hole and add new studs to get another 10mm+)
A cab-star is a small truck. Not a diff assembly.bushy555 wrote:WICKED wrote:Its called a H260.
The really BIG rear diff from a leaf sprung GU is a cab-star.
Looks about twice the size of that of the H260.
And is a true full-floater.

the leaf and 3.0L centres are the same (except a different spline count for the axles i think), the axle size is the same but the leaf diff has flull floaters and the 3.0L is semi floating. leaf diffs and the 3.0L are 4.3 ratio however there is also a 4.2 ratio version but i dont know what they were factory fitted to.bushy555 wrote:>Some Cabstar trucks had a full floating version of the H260, but with

Ok, now Im confused.
The GU leaf sprung ute has this rear diff housing (which I thought was from a cab-star truck - full floater) that is massive in comparison to that of a 3 litre GU rear diff, which I thought was a H260 (3/4 full floater).
It (3 litre GU rear diff) being massive when compared to a H233.
So, what is the housing that is in the GU leaf ute?

also some 4.5L as well (mine does but a mates doesnt)Micka wrote:I thought the H260 was in the 4.8L petrol Patrols and the leafy Utes only. I took notice of a 3L new Patrol today and the rear diff looked uninspiringly small.
3L autos did and manual didnt or the other way round, im not sure.Micka wrote:I thought the H260 was in the 4.8L petrol Patrols and the leafy Utes only. I took notice of a 3L new Patrol today and the rear diff looked uninspiringly small.
Pretty sure they stopped fitting the big diff to the wagons in late 02 when they went to the GUIII.mickyd555 wrote:3L autos did and manual didnt or the other way round, im not sure.Micka wrote:I thought the H260 was in the 4.8L petrol Patrols and the leafy Utes only.
