looking for a 231/300 kit

Fyi box4rocks is not being made anymore. Duffy the box4rocks maker was sued my the mad rooster doubler maker. Just sold my 231 dox4rocks setup. The guy i bought it from said he talked to duffy and confirmed this.

There are many compnies out there doing doublers. A few companies doing build your own setups. Check out north west fab
 
checked out nw fab little high 1300$ for the kit with shifters. I could get a lo 4:1 231 for 1200$ from 4 wheel parts. cant find Mad Roosters off road website.
 
if you do anything at speeds in low gear.... hill assaults, dune running, snow bustin... you do not want the teraflex 4:1 unit. EVEN THEY TELL YOU it is not to be used at high RPMs for extended periods of time.

the issue is oil starvation of the planetary gear.
