A doubler is simply a combonation of a 203 and 205 transfer case. You use the gearbox of the 203 in front of the regualer 32-spline input 205 with a special adapter and you have the option of 1:1, 1.96:1, 2:1, and 3.96:1 ratio reductions. The normal 205 has a 1.96:1 reduction in low and the 203 has like a 2:1 reduction in low...add them together and you get 3.96:1...plus, the entire unit is relatively compact /forums/images/graemlins/thumb.gif Check out ORD for more information...

To explain what Chris just said in a different way:

x2, not +2 (hence the name "doubler"). It's not much diff between 3.96 and 3.92 but if you use a case like a 241 (4.72 vs 5.44) or 3:1 gears in the 203 (4.94 vs 5.88) it will start to matter. If you start talking Klune-V or 4:1 gearsets that are out for some of the Toy &amp; Jeep cases the jumps are bigger.

can you make a doubler out of any t-cases, like a 208 and a 205 or does it have to be a 203 &amp;205?
