      Description

      Made-in-USA Locking Differential Upgrade. The TORQ Locker is a precision-engineered drop-in mechanical locker that transforms your Ford F-250 Super Duty’s traction capability without the complexity of electronic or air-operated systems. Ideal for off-road and heavy-duty use, it delivers consistent torque transfer to both wheels, helping you maintain forward motion even in low-traction conditions. Built for reliability, it's the perfect solution for drivers who want true automatic locking performance with minimal maintenance.

      Construction and Appearance. Manufactured entirely in the USA, the TORQ Locker is CNC machined from premium 9310 steel alloy and heat-treated using proprietary methods in a TS16949 certified facility. It features a key-way cam gear design that eliminates the need for dowel pins or spacers—resulting in a stronger, more durable internal setup. Each unit undergoes rigorous quality control audits, including electron microscopy inspections, to ensure maximum reliability and performance.

      Installation. Installation is straightforward for experienced mechanics and requires no special tools or ring-and-pinion adjustments. It’s designed for use in an open differential but is compatible with some limited slip housings—installation may require additional steps or parts depending on the vehicle configuration.

      Warranty. The TORQ Locker is backed by a four-year warranty with no tire size or horsepower limitations, offering unmatched peace of mind for performance and durability.

      Application. This TORQ Locker fits 1999–2016 F-250 Super Duty with limited slip differential.
