Outer Limits 4x4 Board

hey all..

im replacing the rear diff in my 45 and im just checking to make sure i get the ratio right. im currently running 4.11 diffs and the one i am about to put in has 9x37 stamped on the crown wheel. Is this diff a 4.11 or a 3.7????

cheeers

37 divided by 9 is 4.11 so i would say yes. can you compare it with your old diff?

ahh ok so thats wat 9x37 means!! I still will compare with my old diff once i get it out.

thanks
matt

sweet as man looked like it was the right ratio after all
