This conversion kit accepts the widest variety of drive shaft sizes and types. Kit can be made to work well in any 231 transfer case application

Similar to most other heavy duty conversions but is made to run our unique flange. This allows for the installation of drive shafts in a 1210, 1310, 1330 & 1350 series drive shaft with a conventional two joint or CV (Double Cardan) drive shaft. The kit also allows you to use a 1410 series conventional two joint drive shaft. All without ever having to change the flange!

Who knows where your vehicle will evolve? With our conversion, you’re not limited to one drive shaft size or type. This flange also allows for the convenient mounting of a park brake rotor if you ever need or want.

WE GUARANTEE THAT YOU WILL NEVER BREAK THE OUTPUT SHAFT OR FLANGE!
This is an unheard of guarantee! If your Tom Wood's Custom Drive Shaft 231 Super-Duty output shaft or output flange ever breaks as a result of excessive torque or shock load, we will replace the broken parts or refund the price of the conversion, and we will also pay you $100.00 *
WE’RE THAT CONFIDENT!
