Description
The Detroit Truetrac is a helical limited-slip differential engineered to deliver maximum traction without the maintenance demands of traditional clutch-type designs. If you’re running a GM 8.5-inch rear axle and need predictable power delivery under hard acceleration, cornering, and variable traction conditions, this is your solution. It combines smooth operation with the durability required for both street and track applications.
