I have this here Dana 60



It is a brand new 8 lug single wheel "D" truck Dana, never ran unit with a 4.10 posi (Trac-Loc). It's going in the Ghetto-X, but I've never tried to use a Trac-Loc with 650+ hp (new bullet too ) and wondered if I should just spool it and forget it or attempt to use the posi? I will beat it like a red headed step-child (no red headed step children were harmed in the writing of this post ) and don't want to have to worry about the rearend.

Any input would be greatly appreciated
