Eaton Torque Control Products 912A588 Detroit Truetrac Helical Gear Limited Slip Differential

The Eaton Detroit Truetrac 912A588 is a helical gear-type limited slip differential that delivers reliable traction without the maintenance requirements of traditional clutch-type differentials. As the first helical gear differential introduced to the automotive aftermarket, the Truetrac has established itself as the industry-leading design for dependable torque transfer.

Key Features:

• Helical gear design eliminates wearable clutch packs and friction discs
• Maintenance-free operation with no special fluids or additives required
• Smooth, quiet performance for daily driving and off-road use
• Automatically biases torque to the wheel with better traction
• Works seamlessly in forward and reverse
• Proven durability for street, towing, and off-road applications

The Detroit Truetrac uses a parallel-axis helical gear train to transfer torque between the axle shafts. When one wheel loses traction, the differential automatically sends more power to the wheel with grip, maximizing forward momentum without driver intervention. Unlike open differentials that send power to the slipping wheel, or aggressive lockers that can cause driveline shock, the Truetrac provides balanced traction that's ideal for varied driving conditions. This differential is designed for enthusiasts who need dependable traction without the maintenance hassles of rebuilding clutch packs or replacing worn components.
