Rear Remanufactured Dana M315 4.10 Limited Slip Differential — 2023–2026 Ford F-350 Super Duty Pickup (Standard, Extended, Crew Cab)

When your 2023-2026 Ford F-350 Super Duty's rear differential needs attention, US Powertrain delivers a professionally remanufactured solution built to restore OEM-level traction and drivetrain integrity. This Dana M315 limited slip differential is remanufactured to exacting standards in the United States, incorporating engineering improvements that go beyond simply restoring original specifications — US Powertrain engineers evaluate OEM design characteristics and apply updates where warranted, so you receive a unit that is built smarter than the one it replaces. Configured with a 4.10 gear ratio and a 12.4-inch ring gear, this unit is purpose-matched to the F-350 Super Duty's heavy-duty drivetrain demands. The limited slip design ensures torque is distributed to both rear wheels when traction conditions vary, reducing wheel spin on uneven terrain, wet surfaces, or under heavy payload and towing loads. The differential arrives ready for installation with the differential cover included, eliminating the need to source a companion component separately. The cover is finished in black paint over a steel and iron construction — matching the factory appearance and providing corrosion resistance appropriate for the demanding underbody environment of a heavy-duty work truck. Note: This differential is engineered specifically for F-350 Super Duty dual-wheel and standard pickup body configurations. It is not compatible with cab chassis body styles. Verify your vehicle's body type before ordering.
