Uprated CVS and shafts

TomDK wrote: You're completely missing the point Kirky. This isn't about whether the standard diff will hold up to the stronger shafts or not. This is only regarding 22 splines vs 26 splines. Isn't it pretty obvious that with stronger shafts and joints you'll be moving the weak point?

And to answer your comment on what I have to do to check if the shafts will hold.
What a silly suggestion. Why would I try to provoke a shaft or joint failure? I use my Jimny mostly for competition. HD shafts or not I need my stuff to last the entire race. One of the conditions for winning is having to complete the race on good time. Not possible with broken bits.
Warranty or not. And of course there's a point in having warranty. Anything can break. Even the "mighty" 26 splines stuff from RS.

I think I see the point very clearly Tom and it is everything to do with whether the standard diff will hold up to the stronger shafts because if it doesn't the stronger shafts are a waste of time and money and completely pointless!

Yes it is obvious that by adding stronger shafts you will move the breakages to the next weak point, so why gloss over it when championing these shafts and CV's?

It might be a silly suggestion to you that I want someone to test these shafts to see if the diff holds up and if they match their maker's claim but it's not a silly suggestion to every other person that may be encouraged to buy them by you championing them on this forum! I don't just want your word for it and as Russ is testing them before he sells them and I trust him to test them properly I shall await his verdict!

If I were you and I wanted my kit to last until the end of the race I think I would be testing it before the race to know it was up to the job! This will prevent any un-expected failures from lack of testing when in the heat of competition.

There is no point in having a warranty on the shafts if they lead to the breakage of the diff. The shaft manufacturer isn't going to pay out on the warranty as the shafts are fine still, it's your mangled diff that is the issue! If we know the diff can handle it and a shaft were to break then the warranty will be useful, but at the moment we don't know if the diff can handle it and I make that point.

Anyway, let us know how you get on with them.

Hmmm... all this set my little brain thinking...

I've got the biggerer fatterer superior 26 spline shafts

But what's inside my diff? How strong is the diff?

Remembering it's a Calmini Suzuki Vitara front LSD... 2 pin or 4 pin I thought?

Then I read - www.bits4vits.co.uk/lsdfsm.pdf (this is the manual for the rear, but I suspect the front is the same?)

That looks like a solid + cross in the middle?

How strong is that in relation to 2 and 4 pin diffs? :blink:

well the CV has turned up now so i can make a start, my shafts are 26 spline diff end, i can either

fit 26 spline side gears in the std jimny front diff

fit and convert a rear diff to fit in the front

fit a ARB locker with 26 spline side gears (my best choice, just out of the side gears)

so just waiting on a reply to how long the side gears will be and will probably go for that

Rus

So no 22 splines shaft from you Rus?

So that begs the question, why are they making both if Tomdk claims the 22 spline are superior?

The stock Vitara front diff is a two-pin, when fitting a locker a four-pin Samurai rear is a common upgrade.
