Description
The Detroit Truetrac is a helical-gear limited-slip differential that delivers aggressive locking action without the maintenance headaches of clutch-based designs. For Dana 30 equipped vehicles—whether you’re hitting the track or tackling technical terrain—this unit provides consistent traction while maintaining on-center steering response. Install it once and focus on driving, not on rebuilding your diff every season.
