Eaton Torque Control Products 913A611 Detroit Truetrac Helical Gear Limited Slip Differential

The Eaton Detroit Truetrac 913A611 represents the original helical gear differential design that revolutionized the automotive aftermarket. This maintenance-free limited slip differential uses an innovative helical gear system that provides automatic torque biasing without the clutch packs, friction plates, or other wearable components found in traditional limited slip designs.

Key Features:

• Helical gear design eliminates wearable parts for lifetime durability
• Automatic torque transfer to the wheel with better traction
• Smooth, quiet operation with no chattering or noise
• No maintenance required - no fluid additives or periodic rebuilds
• Performs in all weather conditions including ice, snow, and mud
• Works seamlessly with ABS and traction control systems
• Superior to open differentials for towing and hauling applications

The Detroit Truetrac operates by using the separation forces generated by helical gears to load the side gears against the differential case. This creates friction that allows torque to transfer to the wheel with traction while the opposite wheel is slipping. Unlike clutch-type limited slips that wear over time, the Truetrac's all-gear design maintains consistent performance throughout its service life. Ideal for trucks, SUVs, and off-road vehicles requiring dependable traction without the maintenance burden of conventional limited slip differentials.
