Quaife ATB Front Splines

Hi,

I would like to fit a Quaife ATB to the front diff on my Gen 4 (and rear). My question relates to the number of splines I should specify for the front Quaife ATB, OEM 22 or 26? From what I understand the standard front half shafts should be fine, and if ever not then HD 22-spline aftermarket ones could be considered, so am I correct that there seems no good reason to go for a 26-spline and all the extra bits/expense upfront?

Thanks very much!

It all depends how hard you intend to push it off road 
26 spline shafts will be stronger 
But I'm sure both 22 and 26 spline use the same cv joint

Ultimately what tends to break shafts is wheel spin suddenly and violently stopping such as having a wheel in free air suddenly touch the ground. So as Jack says it really depends on how hard you are going to push, which in turn comes down to the terrain and your mechanical sympathy.

Surely the idea of having a locking diff is to stop the chance of having a spinning wheel in the air situation that can snap a shaft when tyre and earth re-unite.

Rodger you would be surprised how easy it is to lift a wheel in certain situations. Then there is bouncing on the spot on up hill climbs. 
Like Lambert says  (mechanical sympathy)
Also having really low gearing plays I big part 
 

If the suspension is capable of maintaining traction to all the wheels that are driven, then there is no need to add any form of traction control, but as Wild Bill wants to add Quaife Automatic Torque Biasing diffs to his Jimny I assumed that he periodically lifted a wheel and needed the Quaifes to control the inevitable spin out that will result. If you drive a track you will inevitably lift a wheel but Quaifes and the like will control the spin out so that when the wheel drops back it will not be spinning widely but will be controlled so that the damage you mention should not occur.
