jeep tj reduction

If you have a 231 Tera 4:1, second would be a doubler, and the ultimate and best route would be a Atlas Tcase.
 
What year and auto or manual? Advanced adapters has a reduction planetary that replaces the empty tail housing of the 42rle auto. 03 to 09 autos and no change in driveshafts, just one extra shifter. 2.72 low which makes the final ratio 7.4 to 1 with a 231/241.
