    '83-87 Grand National, Regal, T-Type.

    Get the best of both types of differentials.

    ECTED, the dual purpose differential. It stands for Electronically Controlled Traction Enhancing Differential. This is the most advanced differential available today—in normal driving situations it acts like a standard limited slip differential, but when the switch is flipped to "on", the advanced electromagnet is activated and it turns the differential into a full-on locker style differential. This is outstanding for a dual purpose street/strip vehicle, because in normal street driving it's a regular cone/clutch-type limited slip, while at the track you flip the switch on and it acts like a locker with equal power to both rear wheels at all times, no matter what. Leave it to Auburn to come out with this heavy-duty, advanced ECTED differential for Chevrolet rear ends.

    Fits 10-bolt with 8.5"/8.6" ring gear, 2.73 and up gears, with a 28-tooth Side Gear.
