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
