Eaton 917A730 Detroit Truetrac Limited Slip Differential Chrysler 9.25in 31-Spline

The Eaton Detroit Truetrac 917A730 is a helical-gear style limited-slip differential engineered to maximize wheel traction and enhance vehicle handling characteristics. Designed specifically for Chrysler 9.25-inch ZF axles with 31-spline axle shafts, this differential works with all gear ratios.

Key Features:

• Patented parallel-axis planetary helix gear design provides quiet, automatic torque splitting
• Operates as a standard differential under normal driving conditions
• Automatically transfers torque to the wheel with better traction when traction loss occurs
• Maintenance-free operation with no special lubrication or friction modifiers required
• Helical gear design eliminates wearable clutch packs for long-lasting durability
• Smooth, quiet operation in both forward and reverse
• 31-spline configuration for Chrysler 9.25-inch rear axles
• Compatible with all gear ratios

The Detroit Truetrac was the first helical gear differential introduced to the automotive aftermarket and remains the industry-leading helical gear-type limited-slip differential. Its proven design delivers reliable traction enhancement without the maintenance requirements of traditional clutch-type limited-slip differentials, making it ideal for street, off-road, and performance applications.
