Differentials are among the most exposed drivetrain components on a 4x4. Off-road, rocks, ledges, and debris can damage factory covers, risking oil loss and internal gear damage. ARB heavy-duty differential covers are engineered to protect the differential housing, ring and pinion gears, and carrier assembly from off-road impacts while adding structural reinforcement under load.

Engineered for Impact Protection
Manufactured from high-tensile nodular iron, ARB differential covers are significantly stronger than standard stamped covers and help shield vulnerable components from trail hazards. Recessed hardware and optimized geometry help maintain clearance and reduce the chance of hardware damage.
Structural Reinforcement Under Load
Beyond impact resistance, differential covers support drivetrain health by increasing structural rigidity. Reduced housing flex helps support bearing alignment and gear mesh consistency, contributing to longer component life in demanding conditions.
Integrated magnetic features help:
- Capture metallic particles in the oil
- Supports cleaner lubrication
- Improves internal wear characteristics over time

Designed for System Compatibility
ARB differential covers are designed to work alongside Air Lockers, providing protection for both factory differentials and upgraded locking systems. This integrated approach supports drivetrain reliability in off-road, overland, and towing environments.
Built for 4x4
Broad Axle Coverage
ARB differential covers are available for many popular axle platforms and are vehicle- and axle-specific to ensure proper fitment and durability.
