with the RS ones they require 26 spline side gears is that a specialist task to do ? are they bolt or does it require fine measurements and setting up of the diff (which i have no clue about) and is there anything on the stub shaft end that needs to be modified to accommodate the new CV's ?

this may be the decider whether to go 22 or 26 spline.

Surely even with 26 Spline side gears the original diff is not stronger? RS also do a kit that allows you to go 4 pin on the front diff then they do some even heavier duty shafts!

Swapping sidegears is pretty straightforward. But takes a couple of hours probably.

Going from 22 to 26 splines does not affect the strength of the diff itself. It only affects the shaft. But how many of you have ever broken then shaft at the diff end? All shafts I've seen break have been at the CV end or the CV itself.

Also no need to start panicking about weak front diffs and such. How many broken front diffs have you heard talk about on this forum? Supergaz' is the only one I've seen.

The reason why I like the 22 splines design from RCV Performance is that if the shafts or CVs should fail, you can always swap with a standard shaft and you're good to go again. And then it's only a matter of going back to the shop and swap the broken shaft/CV for a new one on warranty. Can you do the same with RS stuff?

I dont think so no, i m not sure if there is any warranty i will call them tomorrow. the RCV ones are for a SJ Sammy i have emailed them about the jimny as i presume the SJ ones wont fit a jimny, also i wonder if the no questions asked warranty applies in the UK ?

what exactley is involved in changing side gears and what can you get 26 spline side gears from SJ sammy rear diff i think?

what appeals to me is they do a conversion kit that allows you to use they re 4 pin centre section and mech locker, i presume you still need to aquire 26 spline side gears, hmmmm but now i am into the realms of needing someone to build this for me

The side gears are inside the diff's carrier -



"Just" a matter of swapping them from 22 to 26 spline...

Jimny rear diff ones fit I think?... although I'm a bit new to Jimneys...! ;)

Here's one of my blogs on fitting a (Vitara) Lockright to give you an idea on stripping and rebuilding a diff...

If you don't fancy doing it yourself... Rockwatt's your man B)

He's recently done my rear ARB locker and machined and installed an LSD for me ;)

Getting to the diff I found the hardest bit! Having worked on Vitaras most of my 'adult' life (although some might argue that claim)...

There's a blog on stripping and rebuilding the front axle here -
