This ARB drivetrain component is the Airlocker Dana 50 30 Spl S/N for 2003-2005 Ford Excursion. Confirm the exact axle or differential model, spline count, gear ratio, carrier break, bearing and seal requirements, air-system compatibility, and all application notes before ordering.
Key Features
- Exact axle, differential, gearing, bearing, seal, and air-system requirements are part specific
- Designed for the listed drivetrain configuration and intended operating load
- With an air bag equipped vehicle for example it is essential that the vehicle's crush rate and air bag triggering is not altered when a bull bar is installed.
- Our exhaustive testing programs ensure ARB bull bars meet these requirements.

Frequently Asked Questions
How do I confirm this fits 2003-2005 Ford Excursion?
Match the axle or differential model, spline count, gear ratio, carrier break, bearing and seal requirements, and every application note.
Does an ARB Air Locker include the compressor and air system?
Only components expressly listed for this exact part are included. Compressors, manifolds, switches, air line, bearings, seals, and installation kits may be separate.
Is professional differential setup required?
Differential installation requires correct backlash, bearing preload, gear contact, torque, sealing, and air-line routing. Qualified drivetrain installation is recommended.
Installation Instructions
- Confirm ARB part number RD158, the complete application, and every required supporting component before beginning work.
- Use the correct service procedure to inspect the axle and differential, then set bearings, backlash, contact pattern, fasteners, seals, and air-line routing to specification.
- Fill with the specified lubricant, test air-system operation when applicable, inspect for leaks and abnormal noise, and recheck after the initial driving cycle.
