    9.25 IFS Conversion 0-3" lift

    to convert to a 9.25 on a stock or cranked 3" lift truck I'm sure you can use a diff drop kit and modify it,I tried it but you would have to shave the diff side fins a little bit like they do on the 8.25,and it just hangs too low since its already bigger.i didn't like this route so i went...
