Description

The Detroit Truetrac transforms your Dana 44 differential into a precision traction tool, delivering consistent power delivery without the maintenance demands of traditional limited-slip designs. Whether you're tackling technical off-road terrain or pushing hard on the track, this unit maintains grip under load while resisting the wear that compromises performance over time. Built from robust iron construction, it handles aggressive driving conditions while staying mechanically reliable mile after mile.
