Eaton Detroit Truetrac Differential 35 Spline 1.50in Axle Shaft Diameter 4.10 & Down Ratio Dana 60HD

The Eaton Detroit Truetrac is an automatic limited-slip differential for Ford Super Duty vehicles, offering enhanced front traction without sacrificing daily drivability. Its helical gear design quietly and smoothly transfers torque when a wheel slips, providing improved traction on various terrains like wet roads, loose dirt, snow, and uneven surfaces. It's designed for direct fitment into Dana 60 front axles, supports 35 spline axle shafts and 4.10 or lower gear ratios, and is ideal for trucks with larger tires or off-road use. This system requires no driver input, has no clutches or wearable parts, and ensures control without the harshness of a full locker.
