1999-2003 Ford F250/F350 7.3L Powerstroke Differentials

Your 1999-2003 Ford 7.3L Powerstroke is already a capable machine, but you can significantly improve its traction and handling with an aftermarket locking differential from Alligator Performance. A high-quality posi-track or locker in your differential case provides power to both wheels on a single axle in low-traction conditions, making it the perfect upgrade for F250 and F350 trucks that handle heavy towing or off-roading. We also offer differential covers to simplify maintenance and add an aggressive look to your truck’s undercarriage.
