Agile Offroad X ARB Air Locker

Real traction when it counts. The Agile Offroad X ARB Locker upgrades your Sprinter’s rear differential with on-demand locking capability that sends power to both wheels simultaneously.

Designed for 2WD, 4x4, AWD, and Dually Sprinters, this isn’t just a locker - it's a complete rear differential rebuild, engineered for durability and performance.
