      Description

      Performance Differential. The Eaton Detroit Truetrac Ford 8.8-Inch Limited Slip Differential for 3.31 and Up Gear Ratios with 34 Spline axle shafts is engineered to enhance traction and handling under diverse driving conditions. It allows for smooth, automatic torque transfer to the wheel with the most grip without requiring driver intervention. This differential improves vehicle stability and maximizes power delivery during cornering and on uneven surfaces.

      Durable Construction. Crafted from high-grade materials, this differential features a robust 8.8-inch ring gear and precision-machined 34-tooth splines designed to endure high torque loads. It has a clean, machined finish intended for reliable performance and longevity under demanding conditions. The unit requires petroleum-mineral based GL5 rated 80w-90 gear oil to maintain optimal internal lubrication and should not use synthetic oils or friction modifiers.

      Ease Of Installation. Installation is straightforward for professionals familiar with rear axle components; no drilling or special modifications are required. The differential is designed as a direct-fit replacement for the factory-installed unit.

      Application. This differential fits Ford F-150 models from 2015 through 2026 with an 8.8-inch axle, 34 spline axle shafts, and gear ratios of 3.31 and above.
