Eaton 913A541 Detroit Truetrac Helical Gear Limited Slip Differential - Toyota 8.4 Inch, 30 Spline

The Eaton Detroit Truetrac 913A541 is a helical-gear style limited slip differential engineered for Toyota 8.4-inch rear axles. This unit features 30 spline construction with 1.29-inch axle shaft diameter and is compatible with 3.54-5.29 gear ratios. The patented design uses parallel-axis planetary helix gears to provide quiet, automatic splitting of torque, maximizing wheel traction while enhancing overall driving characteristics.

Key Features:

• Helical gear design eliminates wearable clutch packs and friction discs
• Maintenance-free operation requires no periodic rebuilds or adjustments
• Smooth, automatic torque distribution in both forward and reverse
• Quiet operation compared to mechanical locking differentials
• Works with standard petroleum-based gear oil (no friction modifiers required)
• Direct replacement for factory open differentials

The Detroit Truetrac maximizes wheel traction and enhances driving characteristics while featuring smooth, automatic operation in forward and reverse. Unlike clutch-type limited slips that wear over time, the Truetrac's helical gear design provides consistent performance throughout its service life. This differential automatically transfers torque to the wheel with better traction, making it ideal for trucks and SUVs used in varied terrain conditions.
