BG syncroshift in trans. diaqueen in t/c and diff. PERIOD

 

BG syncroshift or penzoil syncroshift for trans is the best. Shepard (shepracing.com) drives a 7 second AWD DSM and uses Penzoil synchroshift for his tranny. Diaqueen is the only thing that you can use for the transfercase and rear differential without blowing them up (as far as I know).
