    Rated 5 out of 5 by from Way Better Than Sure Grip Units This is my second TrueTrac unit in the past two years. First purchase was for my '69 Road Runner with a 496 stroker, and this second unit was for a 440 powered '68 Charger. In both circumstances, the unit replaced broken or worn out clutch-type limited slip units that went south in less than 1000 miles of use. These TrueTrac units are far stronger, more reliable, and easier than those units and I haven't broken or worn one out yet. Plus, they don't need the special limited slip fluid or special additives...regular gear oil will do! Installed them quickly & easily (after putting new carrier bearings & races on them) and they provide quiet, fuss-free limited slip when needed, but act like an open carrier everywhere else. Very happy & will continue to use these for my limited slip needs!

    Rated 5 out of 5 by from Excellent product Very impressed. Launches hard, straight, and true. Usually run clutch type in my mopars but tried this due to technology. Handles my 440 without issue.

    Will this Detroit Truetrac Differential Chrysler 8.75" work with a 4.89 gear set ?

    Asked by: jweeks32
    No, it will only go as high as a 4.56 gear set.
