ARB Differential Cover Nodular Iron Protection

The ARB differential cover (also called a diff cover or heavy-duty differential cover) protects your axle's differential and ring and pinion set from rocks, ledges and other off-road hazards. ARB casts it from high-tensile nodular iron. This makes it much stronger than a standard stamped steel cover.

Key Features:

• High-tensile nodular iron construction shields the differential and ring and pinion from impact
• Computer-optimized cross-brace design adds rigidity to the whole axle assembly
• The extra housing strength helps keep the ring and pinion gears meshing correctly, which supports gear life and load capacity
• Extra support for the carrier bearing alignment helps prolong carrier bearing life
• Recessed tensile cap screws and a low-profile drain plug resist damage from obstacles
• Angled exterior surfaces optimize approach and departure angles
• High-power neodymium magnets in the drain plug and dipstick collect metallic wear particles
• The magnet on the end of the dipstick lets you check the oil for early signs of internal wear or damage
• The dipstick/filler cap design lets you adjust the oil level for high driveline angles
• Powder-coated finish resists corrosion

ARB is a respected name in 4x4 equipment. Each cover is built for competition, trail and overland use, where it helps guard an expensive drivetrain component.
