DIESEL TRUCK EXPERTS STANDING BY

Upgrading the ring-and-pinion gears in your 1999-2003 Ford 7.3L Powerstroke is key to regaining lost performance after adding larger wheels and tires or simply building a high performance 7.3L Powerstroke towing rig. These gears help restore power and torque, giving your truck the muscle to excel both on-road and off. For more control and enhanced performance, adding a limited slip or a locker ensures better power distribution between both wheels on an axle, improving traction and grip on even the most challenging terrains. Further, a differential cover not only protects your driveline components but also adds a rugged, custom look to your truck. Whether you're navigating tough trails or heavy-duty towing, these driveline upgrades are crucial for maximizing your F250 or F350's performance. Explore our selection and get your 7.3L Powerstroke ready for any adventure.  Ford Powerstroke Fitments: 1999, 2000, 2001, 2002, 2003 Ford 7.3L Powerstroke. Submodel Fitments: XL, XLT, Lariat, FX4, FX2, Limited, King Ranch, Platinum. Some exceptions apply, please see individual product pages for specific fitments.
