Eaton Detroit Truetrac 34-Spline Limited Slip Differential for 2015-2023 Ford F-150 (3.31 & Up Ratio)
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2015-2023 Ford F-150 (King Ranch, Lariat, Limited, Platinum, Police Responder, SSV, Tremor, XL, XLT) models with 34-spline rear axles.
The Eaton Detroit Truetrac is the industry-leading helical-gear style, limited-slip differential. Unlike traditional clutch-style LSDs, the Truetrac uses a gear-based system that requires no maintenance and features smooth, automatic engagement. This unit delivers a high torque bias ratio to maximize acceleration and handling without the chatter or tire scrubbing associated with locker differentials.
Designed for durability and quiet operation, this differential performs equally well in forward and reverse. Because it uses gears rather than friction discs, it does not require special lubrication or friction modifiers, making it a reliable choice for daily driving, towing, and light off-road use.
- Manufacturer Part Number: 917A739
- Axle Spline Count: 34
- Gear Ratio: 3.31 and Up
- Style: Helical Gear Limited Slip
- Maintenance: No friction modifiers or special additives required
- Performance: Automatic engagement with optimized torque bias
