9'' Differentials

Differentials are available from Cobra Automotive in several types to suit any application.  Trac-Lock posi-units are perfect for hot street to moderate competition use and incorporate a clutch style mechanism to do the job.  True-Trac units can be used for all out competition or street use, their helical gears distribute torque to both rear wheels constantly without freewheeling and ratcheting; for example 20% to the inside tire & 80% to the outside tire while in a turn.  The Detroit Locker is still the choice of many for all out racing because of its all steel locking ratchet mechanism.  Today’s new Detroit Lockers are far quieter and more streetable than the older models.  All differentials are available in either 28 or 31 spline.
