Saw this in the Feb edition of 4WDrive ... alternative to doubling your transfercases but works the same ( and a really short rear driveshaft ), using a lowrange TFC ( like Bushy and more $$$) or regearing ( losing high range gearing) ... seems like a good idea.

http://www.northwestfab.com/NWF-BlackBox-Underdrive-Unit_c_13.html

AND they are coming out with one for the FJ ... so with my 4:1 ... would be x that by 2.72 = 10.88 .... or where my final drive ratio is about 65:1 with 4:56's, .... would be 176:1 !!!! Don't need it tho.

So in Low range, with the black box in low range ...
Bad would be 44.6 x 2.72 = 121 : 1 overall
Ben would be 49.6 x 2.72 = 135 : 1 overall

Hi range is still 1:1 so difference.
Low range ( with the black box in Hi ) no change

$1599 US.
