GV has a stupid air operated front diff. You might be able to swap the GV ratios into a sierra diff. If so then you could have 4.3, 4.8 and 5.12 ratios.
Oh and theX90 has 4.8 diffs

you're better off getting the vitara R&P built into the sierra 3rd member as the vitara one is alloy & known to be made of porcelain reinforced glass.

the higher the number the greater the reduction.... you work it out.
vitara rear diffs are larger than sierra... sierra F/R diffs = vitara front diff in size etc.

yes, it's a step backwards if you fit 4.8's. EDIT: sierra's don't come with a 4.8:1 ratio so I've got not idea WTF you're on about
