Detroit Locker 915A387 Eaton Truetrac Limited Slip Differential Dana 60 35-Spline 4.10 & Down

The Detroit Locker 915A387 Eaton Detroit Truetrac is a helical gear limited-slip differential designed for Dana 60 and Dana 60 HD axles with 35-spline axles. This advanced differential uses a patented design of parallel-axis planetary helical gears to operate as a standard differential under normal driving conditions, but automatically transfers torque to the wheel with better traction when ground conditions change or traction loss is detected.

Key Features:

• Dana 60 HD differential carrier with helical gear design
• 35-spline configuration for 4.10:1 and numerically lower gear ratios
• 10 cover bolts, Series 3 carrier
• Transfers up to 3.5 times more torque to the high traction wheel
• Sealed maintenance-free unit requiring no friction modifiers or adjustments
• Helical gear design eliminates wearable clutch packs for smooth, quiet operation
• Retains torque bias for lifetime with no electronic connections required

Specifications:

• Steel carrier construction
• Uses petroleum/mineral based GL-5 80W90 gear oil (no synthetic oil or friction modifiers)
• No break-in required, though gears will lap together and operate smoother with age
• One year warranty against manufacturer defects

The Eaton Detroit Truetrac differential is ideal for trucks and SUVs requiring enhanced traction for off-road use, towing, snow and mud conditions, while maintaining smooth on-road manners. This all gear-driven clutchless differential automatically provides smooth transfer of power from the slipping wheel to the non-slipping wheel.
