Are the WT and coily transfer cases geared the same?

No, not only are the ratios different, they are also a completely different design.

Would a WT transfer be better for highway driving or the chain driven coily one?

That would depend what tyre size you were running, what diff ratios you were running, and what you wanted to achieve.

WT sierras have 1.409 high range ratios, and 3.7 diff ratios.
Coil sierras have a taller high and low range, but I can't find the exact numbers now.

Fitting a coil sierra transfer case would lower cruise revs a little, assuming that is what you wanted to do. The case will also be quieter as it's a chain drive case rather than geared.

Having said that, I don't think I'd do it - it's only going to a marginal improvement.

I own a coily
So the coil transfer is better for highways and stuff?

Well, it has taller gearing, which Suzuki offset with a shorter diff and 5th gear ratio in the coil gearbox.

Like I said, whether it's better than a WT case depends on what you want to achieve. Swapping to a WT case will raise your revs at 100km/h.

Wt case can have gears And coily cases suck and strip chains
