I called the guys from OTT today and here the scoop. It seems like a preety sweet setup.
You send them your Sidekick Transfercase and then they basically turn it into a "double" (it doesnt have 2w or 4wd drive anymore only your high and low gears) and make so you can bolt up a toyota transfercase. So you would have your transmission, modified sidekick t-case, and then a toyota t-case. The stock sidekick low gear is 1.9:1 and the stock toyota t-case in low is around 2.2:1 I think. So if you have both of them in low you would have around a 4:1 reduction.
But them you can put lower gears in the Toyota case if you want. A completely rebuit Toyota case with 4.7:1 gears from Merlin is only $899. You would have a total of four gearing options to use on the trail. For example with the 4.7:1 kit installed you would have your normal High gears, the 2:1 in the Sidekick case(yota case in high), or 4.7:1 in the yota case (leave the sidekick case in high, but put the yota case in low), or 9.4:1 if you had the sidekick case in low and the yota case in low.
If you put their Kicker 2 kit in you will have to cut your drive shafts, they sudjest putting in yota driveshafts and just make them shorter. and you have to put the zuki flanges where it connects to the differentials on the yota shafts. I hope all this made sense and I hope I have my figuring right. I might just put the stock yota t-case in for a while till I save up for the 4.7:1 kit. The guy said that it should run me about $1000 to do the Kicker 2 kit with the stock yota case. I think this is the route I am gonna go, but we'll see. I gotta come up with the dough first. What do you guys think?
