Description
The Detroit Truetrac is a helical-gear limited-slip differential engineered to maintain traction under acceleration while allowing smooth cornering without bind or chatter. If you’re running a GM 10-bolt and need predictable power delivery without the maintenance headaches of clutch-type units, this is the solution. Install it and forget it—no adjustments, no break-in procedures.
